The power inside of you - ROTTMNT One-shot Leosagi

Small but important info first. This Jotaro belongs to @thewitchwannabe!! CW: Attempted kidnapping, minor injuries. ------------------------------------------------------------------------------

------------------------------------------------------------------------------

It was supposed to be a calm night. 

He was coming home after spending the day between helping with a few crimes and also working part-time at the Hidden City Hospital. He thought he would just eat dinner with his family while Jotaro talked about everything he did in school that day, discuss their plans for the weekend and maybe have his weekly gaming session online with his brothers as normal. 

That was the plan, at least until his communicator started to blast an alarm that put him on edge immediately, holding up his wristband only to hear the worried voice of his twin. 

“Leo! It’s the foot clan!” Donnie sounded like they were running. He could hear Raph’s voice in the background. “I thought that we got rid of the last group, but it turns out that they were preparing for a bigger job! There are a lot of them! I’m sending you the location now.” 

He looked up only to see his husband already on the move, grabbing his sword. He got up, immediately getting his arm, connecting it to the port, and started putting his gear on.

“We’re on our way, Donnie. Do not engage until I get there, we need a plan” He waited until he received the affirmative from his twin before cutting the communication. 

“Dad? What’s going on?” 

Leo turned around to find his 10-year-old son looking between them with a worried look in his eyes. 

“Your uncles are in a bit of trouble but don’t worry, we’ll be back soon.” Seeing the tense look in Jotaro’s eyes, he got down on one knee and put one hand on his son’s shoulder. “Hey, it’s gonna be ok, we’ll be back before you notice. We’ll drop you off at Miss Foster’s and then-“ Jotaro cut him off. 

“No, Dad! I’m not a baby anymore! I can wait for you guys here. I know the rules!” He said determined.

Leo doubted, looking over at Usagi, who seemed to think about it for a second. They needed to go, and Jotaro had recently been determined to prove that he was not a little kid anymore. They didn’t have time to argue with the child. He just started his samurai and ninja training a couple of months ago, and their house was protected by a mystic spell, courtesy of Mikey.

That didn’t remove Leo’s uneasiness.

His husband crouched beside him and put a hand on top of Jotaro’s head. 

“Alright, but you have your emergency button with you at all times, make sure that everything is closed-“ Usagi was now cut off.

“And not touch anything in the kitchen unless it’s the cereals if I’m hungry, and if I don’t feel safe, I’ll run to Miss Foster’s house.” The boy said with a smile, happy to get what he wanted. 

Miss Foster was a fox yokai that lived down the mountain where they lived, having her little sisters living with her and they went to the same school as Jotaro. She had taken care of Jotaro multiple times in the past when both Leo and Usagi were out on missions. 

With a sigh, Leo left a kiss on his son’s forehead and stood up.

“Alright, but be careful, and no staying awake until too late,” He said, swinging his sword down and a blue portal appearing in front of him. 

“Got it! You guys go kick bad guy butt!” Jotaro said as Usagi put him down after a hug. His ears stood up and his little tail moved from the excitement of seeing his parents looking so cool. 

After one determined look from his husband, they crossed the portal to the location Donnie had given, which ended up being the roof of a warehouse close to the docks. 

“Good for you to join us, brother. Hi, Usagi.” Said Donnie while being in a crouched position, eyes locked on his wristband. 

“Usagi!” Mikey immediately went for a hug from Usagi, who happily returned the hug. He was only looking at his big brother when he let out a dramatic gasp “Oh, Hi Leo”

The slider just let out a chuckle, patting his little brother on the head and giving a fist bump to his siblings, before officially shifting to leader mode. 

“Don, what do we got?” From their position, they could see many people moving boxes from one of the warehouses to trucks, nothing indicating actually being the foot clan. 

“After the small groups of the clan were slowly dissolved by Casey and Junior, we found nothing of them for a good year and a half. April got a tip from very suspicious activity running around, and after some other stuff, we found that they have been building the whole clan in secret and now they’re transporting mystic artifacts” They took their goggles off and gave them to Leo so he could take a look. 

He now could see all the mystic energy coming from the boxes and all the foot clan logos on people's shirts and even the boxes, but it seemed to be hidden from the normal eye. 

“It seems that they actually learned stealth now, but I could give a deeper scan to some of the boxes and… they’re all teleportation or portal type of artifact, all related to moving through time and space” The tone of voice of the softshell was enough for Leo to know what they were thinking. 

“Leo, you think that maybe…” His older brother inquired, standing next to him. An uneasy but determined expression on his face. 

“I think so, but the question is: is it possible?” He took off the goggles and passed them back to his twin, now turning to look at Mikey. 

Mikey, after almost two decades of actively practicing and studying mysticism under Draxum’s watch, was the one with the most knowledge on the subject. 

“It shouldn’t, I haven’t heard about any artifact that is capable of that. But if they’re collecting so many… I could think that maybe they’re collecting energy for something else. Either way, I really don’t like it”

Leo agreed with the youngest. Anything that could even come close to thinking about them coming back needed to be shut down immediately. 

The number of people he could see was high, but it wasn’t something they haven’t dealt with before. For this kind of thing, he didn’t mind blowing up some stuff. After having the plan on his mind, he turned back to his family. 

“Don, Mikey, plant some mystic bombs on those trucks, we’re not leaving anything that they could use. Raph, go cover them and deal with the humans closer to the trucks. Usagi and I will go to the warehouse and buy you guys time so you can plant the bombs. Give the signal when you’re done and we get out of there.” 

Everyone gave a firm nod and they went into position. 

Leo and Usagi went to the back of the warehouse and could see from behind some containers how the Foot commander was giving orders around, but they couldn’t see Brute anywhere. 

Something wasn’t right, he could feel it in his gut, but they needed to find out what the hell was going on. 

They both entered the scene, one of Leo’s swords casually against his shoulder and Usagi still tense, but with a sly smile on his face. Still looking down from one of the containers. 

“Wow, you guys went back to the shoe-selling business?” He said, now having all eyes on them. 

Commander let out a frustrated groan. 

“Well but if it isn’t the biggest pain in my butt” We walked to the front and gave them an unimpressed look. “It’s been a while, that’s for sure” 

“I think we haven’t seen you since Warren and Hypno’s wedding?” Wondered his husband. 

“Oh yeah, I thought you guys were going to sell cupcakes and brownies with Cass, you know? Finally stopping villainy and letting us live in peace?” His stance was casual, but he was completely aware of his sibling’s mystic energy outside the warehouse. 

“We would love to, but we do have… unattended matters” His face immediately changed to something sinister. Before Leo even could say anything, he was suddenly trapped in a mystic bubble and fell to the ground, his husband in the same situation beside him. 

He immediately got up, got his swords out, and noticed how he couldn’t open any portals. 

Pink portals opened on top of them and his siblings were dropped from them, all in the same situation and groaning from the fall but recovering quickly. 

The slider was getting angry, and the feeling of uneasiness in his gut got worse by the second. He looked at Mikey, who gave him a tense but secure look on his face and subtly reached for the pouch under his cloak. 

His little brother had a plan and he was going to give him the time to pull it off. He looked at the others, who could only guess right now that he had something in mind. Given that the mind meld didn’t seem to work either. 

“You do realize that we’re not gonna let you bring them back right?” He said confidently. “I didn’t even think that you guys were dumb enough to try but I guess here we are.” 

The smile on the Foot commander didn’t falter, throwing Leo off when he started laughing. 

“Oh, that’s what you guys think we’re doing? No, no, no. But I knew you guys would be concerned if you saw we were opening a portal. The perfect excuse to bring you here and test some new mystic gadgets!” 

“Then what’s the point? You just want to kill us?” Raph asked

“Oh well, I know that I won’t be able to hold you guys for long, You all have grown so much! Now with new lives, and even getting married!” He pointed at him and Usagi. 

The villain's monologue was buying them time, but there was something in his tone that was making his anxiety spike. 

“You’re way too strong, right? So we needed a weak point! Something to finally help make amends for almost twenty years of ruining everything.” He stopped on his track and looked him straight in the eyes. “By the way Leonardo, how’s your son?” 

He felt as if his heart stopped. He knew it, he knew something was wrong. Jotaro was alone in their house. 

“Get the fuck away from him!” His husband’s yell snapped him out of his surprise, deep anger finally setting in. 

He could hear Raph pounding on the glass of the bubble and feel a strong aura of anger coming from his twin. 

“I swear to god, if you even get near him-” He cut himself off when the sound of the emergency button of his belt blasted an alarm, making his stomach drop in fear when he saw the light blue on it.  

Usagi looked at him with pure panic in his eyes. 

Jotaro pressed his emergency button. 

——————————-

Jotaro, being a rabbit, had really good hearing. 

When he started training with his parents, getting both samurai and ninjutsu training, it was one of the first things that they remarked. Saying that it was a tool of great advantage if he knew how to use it right. 

He remembers the game they used as an example. They were in the middle of the woods on a Saturday evening, his Papa sitting crossed-legged in front of him, eyes closed in concentration while his Dad was nowhere to be seen, hiding in the shadows.

It was extremely interesting seeing how his father’s ears twitched with every slight movement, standing prideful and attentive to any sound. 

Without warning, the older rabbit threw a Kunai to the top of one of the trees, being quickly met with a yelp and his Dad fell from the tree without a sound.

“Found you” It was fun to see the smug smile on his father’s face, but even more hilarious was the pout on Leo’s face as he walked with the Kunai in hand. 

“I know somehow you’re cheating” The turtle squinted his eyes in playful suspicion, making him giggle while his father rolled his eyes.

“Keep telling yourself that,” He said to his husband before turning back to the child, “Ready to give it a shot?” 

Jotaro nodded excitedly, before crossing his legs and copying the position Usagi had before.

“Good luck Jojo,” Said the ninja with a playful smile, and with the blink of an eye, was gone again. 

“Now, close your eyes and focus on the sounds, be detailed and attentive, and look for what stands out. ”Usagi explained in a whisper. “Point at him when you find him”

He nodded and closed his eyes, letting his ears stand straight, attentive to everything. 

He could hear the trees, the leaves that moved with the slight wind. The smallest animals moved through the forest.

Thud

Thud 

He opened his eyes, surprised by the sudden small sound. His father had a smile on his face that told him to continue.

Closing his eyes again, he looked for the sound again until he found it.

Thud

Thud 

It wasn’t consistent, so it was definitely his Dad going from one tree to another, he had to pay a lot of attention just to hear that small sound. His turtle dad was huge and heavy, how did he manage that? 

He followed it, finding the path that the turtle was following, and at the same time as the sound, he pointed to behind the tree on his right.

“There!”

“Great job bud!” Leo congratulated, coming from behind the tree he pointed at.

“That was great Jotaro!” Usagi praised him while hugging him tight.

He beamed at the congratulations and wanted to try again. 

After that, he was much more aware of the sounds in his surroundings, especially the steps. 

His dad’s were quiet, even when he wasn’t trying to be. His uncle’s almost all the same. Except for Uncle Raphie, whose steps could be a little heavier. But if he was trying, it was the same as his brothers.

His papa’s were a little louder, steps were firmer but he was still very light on his feet.

So when he heard the heavy steps around the house while he was getting ready for bed, he immediately knew it wasn’t his parents.

Alarms blasted in his mind, a feeling in the pit of his stomach telling him to hide. 

Not knowing what else to do, he took his plushie and his button and immediately hid in the closet, burying himself under a pile of clothes. 

His mind was racing between all the people he knew, thinking who may be, he could hear them coming down the hall, but he didn’t recognize the steps. 

“Where the hell is that kid?” He heard it was a man, voice deep, and he was looking for him.

Without a doubt, he pressed the button, which thankfully didn’t make any sounds, but it did have a blinking blue light. 

It was a matter of time. He knew that now he only had to stay hidden until his dads got here. They will get here as soon as they can, Jotaro just had to wait.

He concentrated on keeping an ear out for whoever was outside. He was checking down the hall, opening the doors to the rooms. The closer he got, the harder it was for Jotaro to focus with the loud thumping of his heart against his chest. He tried his best to focus, any information he could get about the enemy was an advantage to him. 

Taking a deep breath, he tried to listen again, still clutching the button close to his chest. His parents will come for him. His parents are gonna save him. He just had to hang on. 

His stomach dropped when he heard the door of his room open. 

By pure instinct, his ears dropped and he curled into himself in the pile of clothes that thankfully covered him completely, trying his damn best to not move a muscle. 

The steps were still heavy, but the man didn’t talk. 

The door of his closet was closed, but he couldn’t even dare to open his eyes. He was shaking and crying. Not wanting to give away his hiding spot. He just had to hold on. 

“Here you are” 

He only felt one big hand grabbing him by the arm and yanking him out of his hiding spot. 

-----------------------------------

“No!” Usagi banged his hand on the bubble. Angry tears formed in his eyes. “Stay away from him!” 

Lieutenant only laughed in their faces. 

“You’re dead.” Leo’s voice was cold with that promise. “You won’t get away with this” 

Before the Lieutenant could even start his sentence, Leo felt the rumble of his little brother's ninpo. The chains, usually reserved for extreme circumstances, as it drains his little brother’s vital energy if he passes his limit. It wraps around each of the bubbles, bursting them in a matter of seconds. Foot Lieutenant already making an escape portal.

Leo was gonna throw himself against Lieutenant. They couldn’t let him go. He was immediately stopped by a chain wrapped around his wrist. Ready to snap at his brother to let him go. 

“Leo! We don’t have time!” Mikey’s worried look was enough to dissipate the anger into pure fear. Jotaro. 

Looking around, his family was also stopped by Mikey’s chains and the Lieutenant was crossing his escape portal. 

With one more furious look, he swung his sword, making a big portal that immediately swallowed all of them, dropping them in front of his house. 

“DADDY! PAPA!” 

The image in front of him made him freeze.

The brute was creating an escape portal while holding his son by the ears. His eyes filled with fear and crying as he reached an arm towards them. 

“JOTARO!” He screamed out of instinct, already running towards them with his husband by his side. 

The escape portal was done and Brute was one foot in it, they wouldn’t make it in time. 

No, no, no, no, no, NO, NO- 

Just when he thought that he would get his son taken from them. Something exploded. 

A strong light blinded them, a force strong enough to stop them. Just managing to hear a painful scream from Brute. 

Looking up from where they were, Leo managed to see Jotaro’s spots around his eyes glow. It was a strong blue that reminded him of his own. Being able to feel that same sensation that he had for all his brother’s and sister’s ninpo, the difference being that it was a very, very strong energy coming from his own son. It was Jotaro’s ninpo. 

The energy seemed to manifest as electricity. As it was enough to burn Brute’s hand to the point that it forced him to let go of Jotaro. 

As soon as he saw the opportunity, he ran. Mikey’s chains immediately grabbed Brute and threw him a good 10 meters away from them as the escape portal closed. 

“We got him, Leo!” Raph yelled as he ran with Mikey towards Brute. Letting him focus on Jotaro. 

Usagi immediately extended his arms to grab him. But the same electricity as before was still coming out of the child, not letting him even touch Jotaro without electrocuting himself. 

“...Ugh… d-dad- AH!” Jotaro cried, and Leo could easily see the small electrical burns starting to form around his little arms and legs. 

“Jotaro! Donnie what’s going on?!” He immediately asked his twin as he was looking at Jotaro, goggles down. 

“I-It’s his mystic energy! It’s responding to the high stress and panic and is going off the charts!” He quickly explained. 

It was like Mikey’s. By now they all knew that mystic energy, especially their ninpo’s, responded to their emotions. Jotaro needed to calm down. 

“Jojo, baby, look at me.” Usagi reached the same conclusion as he did, slowly sitting in front of Jotaro and trying to remain as calm as he could. If Jotaro saw them panic, he would panic even more. 

Jotaro lifted his head, obviously hurting from the mystic powers and still scared out of his mind. 

“I need you to breathe with me, alright? You’re safe love, we got you.” The voice of his husband was calm, even if his eyes teared up from seeing their son like that.  

He followed Usagi’s lead and sat down beside him, giving Jojo a small smile, also feeling the small knot form in his throat at the heartbreaking sight. 

“You did good buddy, you did amazing today. It will go away, I promise but I need you to breathe.” Both he and Usagi started to guide Jotaro. Who even in his panic, slowly started to follow them. 

As Jotaro worked on slowing his breath, the glow on his spots started to fade. 

Already desperate, he took off his arm, which had the chance of short-circuiting and he offered his hand to Jotaro. 

His own ninpo had a small touch of electricity that he always felt, especially when he teleported from one sword to another. Donnie had confirmed it years back as they always heard a buzz when he teleported near them and got curious. So he knew his body had certain resistance to it. 

He also couldn’t stand seeing his son suffer for another second and not being able to comfort him. 

Jotaro slowly reached towards Leo, but flinched back seeing as the electricity that came from himself could hurt his dad. 

“Hey, hey, it’s okay Jojo. You’re not gonna hurt me, nene, I promise.” He said quietly, not looking to make the child go into a panic again. 

Looking more sure at Leo’s words, he took his hand. Getting close and immediately wrapped his arms around him. 

It was much stronger than his own ninpo for sure. But he could handle it. He would handle anything for him. Not hesitating a second before wrapping his own arm around the child. 

“You’re okay, You’re okay.” He immediately started to whisper, rocking calmly back and forth. 

The electricity faded with every deep breath Jotaro took, feeling safer in his dad’s arms. It was probably still more than Usagi could handle, but he didn’t seem to care as he leaned his head on Leo’s shoulder and started to slowly run his hand through the child’s head. Quietly singing the Japanese lullaby that he sang to Jotaro since he was a baby. 

This seemed to do the trick, as the glow faded from Jojo’s face and he fell asleep in his dad’s arms. His ninpo finally calmed down. 

Both he and Usagi sighed in relief and stood up. From what he could see, Jotaro had small 1st-degree electrical burns on his arms and legs, the worst looking ones being around his forearms and hands. But none of them were reaching 2nd degree, which was good. 

Usagi definitely had a couple on his hand. But they were okay. Wounds could be treated when they were safe. The most important thing was that Jotaro was with them. 

He looked Usagi in the eyes, immediately noticing the silent request on them, and carefully passed him their still-sleeping child. Who he hugged close. 

He turned to his brothers who were waiting a couple of feet from them. 

But Brute wasn’t there. 

“Where is he?” His voice was tense. 

“Mikey had him, but the mystic bubble appeared around him and before he could pop it, Brute was gone.” Raph quickly explained, his voice letting out the same frustration he felt. 

“I’ll talk to Draxum first thing in the morning tomorrow about those bubbles. I had to use the stored energy that I had on some crystals, but I basically emptied them out just to pop my own bubble.” Mikey said, equally as frustrated “I never saw this before, but we’ll take care of it.” 

He forced himself to take a deep breath, they’ll take care of the foot later. 

“Is Jojo okay?” Mikey asked, his eyes concerned as he watched the Jotaro sleep on Usagi’s arms. 

“It was his own ninpo, it must have activated because of the high stress of the situation. It’s very, very powerful” Donnie said, laying the facts in front of them. 

Whoever didn’t know him would say he sounded emotionless. But he knew better. Donnie was just as concerned as the rest of them and was probably already thinking of a way to help Jotaro control his powers. 

“He’s okay, it looks like his body has a good natural resistance to it, but he still has some first-degree burns that I need to take a look at.” He said, before sighing again. “I think we’ll move to the lair for the time being.” 

“Not you assuming that I will let you back before improving your security system,” Donnie said, making him let out a small chuckle as he opened a portal to the lair. 

They let Usagi cross first with Jotaro and they followed behind. Making a beeline for the med bay as Donnie, Mikey, and Raph went to talk to Dad.

Jotaro was absolutely exhausted, managing to sleep through all the procedures of Leo taking care of his injuries. Probably helped that he was still in Usagi’s arms, the sweet lullaby being the only thing filling the silence of the med bay. 

It wasn’t until they were both laying down on the bed of Leo’s old room, which had been modified years ago to fit the three of them. Jotaro now sleeping soundly between the two of them, Usagi looked at him with a look that promised revenge.  

“They’re going to pay for this.” He whispered to him, as he nodded. 

“We’ll find them ‘Sagi, I promise.” We cupped Usagi’s cheek, who sighed and finally seemed to relax, as he hugged Jotaro to his chest and snuggled closer to him. 

It wasn’t long until he noticed that his husband fell asleep. As he stared at the wall with one thought in his mind. 

He was never going to allow something like this to happen to his family again. 

------------------------------------------------------------------------------

EXTRA SCENE 

After Usagi fell asleep, their son in his arms, he quietly got up and went to his twin’s lab, knowing for sure that he was awake. 

The events of the night before came back to him, anger and frustration rising in his chest. His son was almost kidnapped in front of his eyes. If it wasn’t for Jotaro’s ninpo, he didn’t know if he was going to make it in time. He never wanted to see that look of pure pain and fear that he saw in his husband’s eyes while he held their son, who was hurt by his own ninpo. 

The image of Brute holding his son by his ears was clear in his mind when he made it to the door of the lab. 

The doors opened for him, and his twin sitting in his chair turned back to him. 

He quietly walked until he was standing beside Donnie. 

“You’re looking for them?” Leo asked, his voice serious and tense.

“Right now brother, you’ll be the first to know when I find them” His twin's tone matched his own. “This is not happening again. I’m also working on a better security system for your house.” 

“Thanks, Don, let me know when you have any leads.” He stayed silent for a second “We’re finishing this, we should’ve done this the moment the invasion ended” 

“Doesn’t matter, we’re finishing it now. I have weapons with their names written on them.” Donnie’s voice was angry and cold.

Donnie remembers the panic and pure anger he felt when Foot Lieutenant asked his brother about Jotaro. His nephew. His family. 

Those fuckers won’t see another day if he has a say in it. 

“Good,” Leo said coldly.

Donnie couldn’t imagine how his brother felt after this. But what he was sure of is that, as usual, Leo and he were on the same page. 

Mikey had gone to the kitchen for a midnight snack, not being able to sleep. 

He noticed Leo go into Donnie’s lab. 

Just hearing a bit of their conversation was enough to know what the twins were planning. 

Mikey turned his back and went back to bed. He hoped the twins had fun.
