Mattheo Riddle Headcanon

Warning: This piece contains themes of possessiveness, obsessive behavior, and dark romance undertones. Mattheo's love might be overwhelming, intense, and not suited for everyone’s taste. Reader discretion is advised.

(+ Requests are open so if you wanna request something, go ahead)

Mattheo Riddle

౨ৎ 6’2 | He’s not as tall as Theo, but you wouldn’t dare mention that unless you want to end up against a wall (and not in the fun way—well, not just the fun way). He’s tall enough to tower over you, and honestly, that’s all he needs.

౨ৎ Built to fight | Mattheo doesn’t have the lean elegance of Theo or Draco. He’s solid—broad shoulders, strong arms, and that delicious combination of athletic and dangerous. (He’s fought more boys in Hogwarts hallways than you’ve taken exams, and every single one of them regretted it.)

౨ৎ Hands? MADE FOR SIN. Big, veiny, and calloused from Quidditch and street fights. He’s got a grip that can pin you down or pull you close—whatever mood he’s in. (He could choke you mid-argument, and you’d thank him afterward. RESPECTFULLY.)

౨ৎ He doesn’t work out for fun—he works out to survive. Fistfights, dodging hexes, getting thrown into detention every week; it’s all part of the “Mattheo Maintenance Plan.” (He calls it cardio; we call it hot as hell.)

౨ৎ Face? Pure trouble. Mattheo’s got that sharp jawline and cheekbones that could cut glass. Dark, stormy eyes that smolder like embers, framed by lashes so long they should be illegal. He’s always got a cut or bruise somewhere on his face—his version of an accessory. (You just want to kiss it better, don’t lie.)

౨ৎ Hair? CHAOTIC. Dark and curly, it looks like he ran his hands through it during a fight and then just left it that way. It’s thick and soft, and you know it’d feel like heaven wrapped around your fingers. (Or gripping your thighs while he devour —anyway.)

౨ৎ That smirk. It’s a weapon. Crooked, cocky, and knowing, it has the power to make you forget how to breathe. He knows exactly what he’s doing when he throws it your way. (And you hate yourself for falling for it every single time. But not enough to stop looking.)

౨ৎ He doesn’t just walk; he prowls. There’s a predatory grace to the way Mattheo moves, like he’s always two seconds away from either a fight or dragging you into a dark corner. (You wouldn’t mind the later one, do you?)

౨ৎ Voice? A slow burn. Low, raspy, and smooth, like he’s smoked one too many cigarettes but still has you hanging on every word. When he whispers, it’s game over. (He calls you “trouble” in that tone, and suddenly you’re ready to commit a crime.)

౨ৎ Anger Management Issues | Mattheo doesn’t yell—he doesn’t have to. His rage is cold, quiet, and calculated, which somehow makes it ten times scarier. He’ll get even, and he’ll do it in a way that leaves scars. (Emotionally and physically.)

౨ৎ Fight first, ask questions never. Mattheo’s solution to any problem is his fists. Someone looked at him wrong? Fight. Someone disrespected Theo or Draco? Fight. Someone dared to breathe near you? FIGHT. (And he’ll win, obviously. Look at him.)

౨ৎ Slytherin Prince energy. He doesn’t care for titles, but people gravitate to him anyway. He’s magnetic, exuding a dangerous charisma that makes you want to follow him—even if it means walking straight into hell.

౨ৎ Soft spots? Hidden under lock and key. Mattheo doesn’t open up easily, but when he does, it’s devastating. A rare, crooked smile or a quiet laugh, and suddenly your whole world tilts. (We LOVE a secretly soft bad boy.)

Would you let Mattheo Riddle ruin your life? Absolutely. Would you thank him afterward? Also yes. (No notes. Just him.)

Mattheo Riddle | Personality

౨ৎ He’s loud but in that dangerously calm way when it matters most. Mattheo knows exactly how to push buttons, whether it’s with a smirk, a biting remark, or just the way he looks at you like he knows all your secrets. (Spoiler: he probably does.)

౨ৎ The type of person who thrives in chaos. He’s not a troublemaker by default; he just is trouble. People either avoid him completely or flock to him like moths to a flame—usually the latter. (WE LOVE A MAN WHO IS THE RED FLAG AND THE WHOLE DAMN CARNIVAL!)

౨ৎ Reputation? Notorious. Everyone knows Mattheo Riddle. Maybe it’s because he’s always at the center of some scandal, or maybe it’s just because you can’t not notice him.

౨ৎ Manipulative, but make it hot. He doesn’t need to raise his voice or even argue much. Mattheo knows how to twist words and situations until you’re the one apologizing to him. (And then he has the audacity to smirk about it.)

౨ৎ Fights aren’t something he picks—they’re something that find him. But once he’s in one? All bets are off. "You wanted this. Don’t start crying now."

౨ৎ Unlike Theo’s quiet menace, Mattheo fights loud. He taunts his opponent with sharp quips and cruel laughter, the kind of guy who’ll land a punch and then casually fix his hair like it was nothing.

౨ৎ Obsessive tendencies galore. When Mattheo decides something—or someone—is his, it’s game over. He doesn’t just like you; he fixates. (Good luck trying to shake him off because you’re not going anywhere.)

౨ৎ Affection? Worship disguised as possessiveness. He’s the type to follow you around like a shadow, making sure everyone knows you’re off-limits. His jealousy? Immediate and obvious. "If you wanted to make me mad, congratulations, princess. Now, what are you going to do about it?"

౨ৎ He’s a natural flirt, but it’s not rehearsed. Everything about Mattheo is raw, instinctive, and dripping with confidence. (The man could make tying his shoes look like foreplay. It’s unfair.)

౨ৎ Smirks more than he smiles, and every single one is lethal. It’s the kind of smirk that makes you rethink your life choices. (Like why you aren’t currently pinned against a wall by him.)

౨ৎ His anger is a wildfire—hot, destructive, and consuming. But what’s scarier is the moments right before he snaps, when his voice lowers and his eyes darken. That’s when you really start praying.

౨ৎ Chaotic protector energy. Mattheo doesn’t have many people he’d go to the ends of the earth for, but if you’re one of them? He’ll burn the world down to keep you safe. (And he’d make it look sexy while doing it.)

He’s not just passionate; he’s intense. Whether it’s fights, emotions, or sex, Mattheo doesn’t do anything halfway. He’s all-in, all the time. (Exhausting? Yes. Worth it? Also yes.)

Would you let Mattheo Riddle ruin your day, your life, and your sanity? Absolutely. Would you regret it? Never.

౨ৎ Layers of chaos. On the surface, Mattheo looks like he’s got everything under control—swagger, confidence, and a devil-may-care attitude. But under all that? Oh, he’s a mess. Overthinks everything, but you’d never know it because he masks it with a cocky grin and impulsive decisions. (SOMEONE GIVE THIS MAN A THERAPIST, BUT ALSO LET HIM KEEP THE TOXIC EDGE. WE LOVE IT.)

౨ৎ Moody as hell, but in the hot way. You’ll know when he’s upset because he gets too quiet, that jawline clenching just so. He won’t lash out; instead, he’ll brood in the corner until someone’s brave enough to poke the bear. "Yeah, I’m fine. Why wouldn’t I be? *Smirk.* " (Sir, that smirk says you’re about to burn the whole castle down.)

౨ৎ Impulsive to the core. Plans? Never heard of them. Mattheo acts on instinct—whether it’s throwing a punch or dragging you into an empty corridor because he needs you right now. It’s a miracle he hasn’t landed himself in Azkaban.

౨ৎ Organized chaos. His notes are scribbled, his robes are half-untucked, and yet he’s always prepared. Somehow. He doesn’t stress about the details; he just wings it. (And annoyingly, it works out every time.)

౨ৎ Languages? Oh, he knows a few. His Italian is rough but so hot, especially when he’s muttering something under his breath that you can’t quite catch. And Merlin help you when he growls something in Parseltongue. (THE THINGS WE’D LET HIM DO IN THAT LANGUAGE.)

౨ৎ Smart but reckless. Mattheo doesn’t study much, but he’s one of those annoyingly brilliant types who can pick up a spell by watching someone else do it once. He’d ace every class if he cared enough to put in the effort.

౨ৎ Social butterfly with teeth. He thrives in social situations—not because he’s polite, but because he’s got the charisma of a goddamn snake. Everyone either loves him, hates him, or fears him. Sometimes all three at once. "Hey, sweetheart. Didn’t think I’d catch you looking, but here we are." (Boy, nobody was looking. But now we are.)

౨ৎ Driest sense of humor. Mattheo’s sarcasm is so sharp it could cut glass. Half the time, people not sure if he’s joking or insulting them.

౨ৎ But according to him you look good in everything. Wearing a garbage bad? "Oh baby, You look like goddess"

౨ৎ Drinks tea like an old man. (Yeah, you thought he’d be a whiskey guy, didn’t you? Nope. Earl Grey, no sugar, no milk. Deal with it.)

౨ৎ Parties are his stage. Mattheo doesn’t just attend parties—he owns them. Whether he’s in the center of a fight or the middle of the dance floor, he’s the one everyone’s watching. And if he’s not? He’ll make sure he is. "Draco’s drunk, Theo’s being boring, and you’re coming with me. Now."

౨ৎ Protector vibes, but make it chaotic. Mattheo will fight anyone, anywhere, at any time if they so much as look at his friends the wrong way. But he’s not the silent type—oh no, he’s the guy yelling insults mid-fight and making sure the whole room knows why this person deserved it.

౨ৎ Would you trust Mattheo Riddle to make a single responsible decision in his life? No. Would you follow him into the chaos anyway? Absolutely.

Mattheo Riddle | Boyfriend

Oh, dating Mattheo Riddle is like dating a thunderstorm: chaotic, intense, and utterly mesmerizing. He’s a mix of reckless devotion, gentlemanly gestures, and just the right amount of toxic edge to keep things interesting.

౨ৎ The Fighter You Can’t Stay Mad At:

Let’s get this out of the way: Mattheo is always getting into fights. Whether it’s over you, his friends, or just because someone looked at him wrong, his knuckles are perpetually bruised.

You’ve become an expert at patching him up, and even though he winces when you clean his wounds, he sits still because you’re the one touching him.

But the second you start crying while bandaging him up? Oh, his heart shatters. He’d rather die in the ring than see tears in your eyes. "Baby, please don’t cry. It’s just a scratch—I’m fine, I promise." (Spoiler: It’s not just a scratch, but he’ll never admit it because he can’t stand upsetting you.)

౨ৎ The Open Book:

Mattheo tells you everything. Even the dumb stuff that doesn’t matter.

He’ll burst into your room with stories about the dumb prank Theo pulled or the argument he had with Draco over which Quidditch team is better.

It’s not just oversharing—it’s that he wants you to be part of every aspect of his life. You’re his person, and he doesn’t hold back. "Guess what? Draco tripped on his robe this morning, We saw his penis, and Theo nearly died laughing. You should’ve been there—it was glorious."

౨ৎ Your Number One Listener:

If you’re a talker, Mattheo listens like your words are the most important thing in the world. He’ll nod, ask questions, and remember everything.

You’ll mention something in passing—like wanting to try a new dessert—and two weeks later, he’ll surprise you with it.

And if someone interrupts you while you’re talking? Oh, they’re about to meet a very pissed-off Mattheo. "She wasn’t finished speaking. Shut up and wait your turn."

౨ৎ Gentleman With a Hint of Chaos:

Despite his bad-boy demeanor, Mattheo has a surprisingly soft, thoughtful side.

He carries pads or tampons for you, keeps a hair tie around his wrist just in case, and always has a water bottle on hand because you forget to stay hydrated.

He’ll open doors, walk on the side closest to the street, and make sure you’re warm when it’s cold. (But let’s be honest, he’ll also yank you into a broom closet mid-conversation because he needs to feel you right now.)

౨ৎ Hopelessly Devoted (But Low-Key Toxic):

Mattheo worships the ground you walk on, but don’t mistake that for him being easygoing. Oh no. His loyalty comes with a dark, possessive streak.

He’s not the type to tell you who you can or can’t talk to, but rest assured, anyone who crosses a line with you will regret it.

You can do anything, like literally anything. You can kill a guy and all Mattheo would do is kiss your forehead and hide the body. According to him you are never wrong. You can slap him, punch him, or worse kill him he would still justify it saying there must be a reason behind this.

He’s subtle but scary when it comes to protecting you. A cutting glare, a whispered threat, or just his mere presence is usually enough to keep people in line.

౨ৎ How He Fell in Love:

Mattheo thought he was immune to love. Sure, he flirted and hooked up, but real feelings? Nah, not for him.

Until you came along.

It hit him during one of his usual brawls. He glanced at the crowd, and there you were, looking so worried. And suddenly, getting punched didn’t matter—making sure you never had to worry about him like that again did.

Afterward, he was awkward as hell trying to tell you how he felt. He didn’t have Theo’s calculated charm or Draco’s smoothness. Instead, he just blurted it out one day while you were laughing at some dumb joke he made. "I love you. Like, I think I’d die if you ever left me, so… yeah."

Your stunned silence nearly killed him, but then you kissed him, and he knew he’d never want anyone else.

౨ৎ Ride or Die Energy:

Mattheo isn’t just your boyfriend; he’s your partner in crime.

Whether it’s sneaking into the Restricted Section, hexing someone who pissed you off, or just holding your hand while you rant, he’s always got your back.

He might be reckless, dramatic, and a little toxic, but he’s also fiercely loyal, endlessly devoted, and absolutely crazy about you.

Dating Mattheo Riddle? Exhausting. Chaotic. Perfect.

Mattheo Riddle | Affection

Mattheo Riddle isn't the type to pour out his feelings in grand speeches or dramatic gestures—no, he's far too intense and possessive for that. But when it comes to affection? He’s got a way of showing it that’ll make you never doubt how much you mean to him.

౨ৎ The Quiet, Intense Affection:

Mattheo is a man of action, not words. He won’t always tell you he loves you, but his touch? Oh, it says everything.

His hand on your waist when you walk through crowded hallways. The way his fingers graze your back when you’re standing too close to someone.

In public, he’s cool and calm. But when it’s just the two of you? He’s all about that quiet intensity that makes your heart race.

If someone tries to flirt with you? He’ll just stand there, leaning against a wall with a smirk, eyes dark and unreadable, watching. He doesn’t need to say a word; everyone knows you’re his.

౨ৎ Praise Kink, Because Why Not?

Mattheo lives for praising you, but not in some sugary, over-the-top way. No, his words are quiet, almost off-handed—but they hit like a freight train.

"I don't know how you make doing nothing look so fucking sexy."

“You’re brilliant. You’ve got this whole school eating out of the palm of your hand, and I love it.”

He’ll say things that seem like offhand compliments but are actually his way of making it clear you’re the most important thing in his life. You’ll think about it later, and that’s when it hits: he means it.

౨ৎ Acts of Service—Mattheo Style:

Mattheo won’t jump up and start fussing over you the second you’re upset. He’ll do it in his own way—quietly, but with a look that says he’ll take care of you.

He won’t tell you when he’s bought your favorite candy or snuck into the library to grab the book you mentioned once.

"You said you were feeling stressed, so I already cleared your schedule for the week," he’ll say, as though it’s no big deal. (It’s a huge deal, but he’ll never admit it.)

If you’re tired and need a break, you can bet Mattheo will be the one to drag you out of the common room for a walk, simply so you can breathe without all the chaos.

౨ৎ Possessiveness, But Make It Sexy:

Mattheo doesn’t have to raise his voice or throw punches to show how much you’re his. His possessiveness is felt—a deep, simmering intensity that wraps around you.

At parties, his hand is always on you. Resting on your back, on your thigh, on the curve of your waist. Every touch is a claim, subtle but strong.

He doesn’t need to make a scene when someone flirts with you. Instead, you’ll see him lean in, whisper something in your ear, and the person who was trying to flirt with you? Suddenly, they’ll lose interest.

"I believe you’re standing a little too close to her," Mattheo will say, his voice smooth, and then? Instant silence. You’ll never see that person again.

౨ৎ The Soft Side of Mattheo:

Don’t be fooled by his hard exterior—Mattheo has a surprisingly soft side, but only when he’s with you.

He loves wrapping you up in his arms, his strong hands gently cradling your head as he runs his fingers through your hair. The moment the world is quiet, Mattheo will pull you closer, murmuring things only meant for you.

"You’re the only one who can make me feel like I can finally breathe," he’ll whisper, kissing your forehead like it’s the most sacred thing in the world.

He’s the type to hold you while you fall asleep, his hand resting on your back, as though he’s terrified of letting you go.

౨ৎ Mattheo Riddle, the Perfect Boyfriend:

He’s everything you didn’t know you needed. Intense, protective, and slightly toxic, but in the best way possible.

He’ll fight for you, adore you in his own way, and make you feel like you’re the only one in the world.

It’s the kind of love that burns, but in the most thrilling, heart-stopping way possible.

Because, at the end of the day, Mattheo Riddle isn’t just your boyfriend—he’s your protector, your love, your obsession.

And honestly? You’d never want it any other way.

(So yeah, you might occasionally hate how possessive he is, but you love it. Let’s be real, you know he’s all yours and you wouldn’t have it any other way.)

Mattheo Riddle | Obsessive Devotion

If Theodore is calculated destruction, Mattheo Riddle is reckless chaos. He doesn’t just want you to fall apart; he wants to be the reason you can’t put yourself back together. With Mattheo, it’s raw, unrelenting intensity—the kind that leaves you breathless, marked, and utterly ruined.

౨ৎ The Firestarter:

Mattheo thrives on tension, but unlike Theo’s slow burn, Mattheo’s approach is an inferno. He’ll corner you in dark hallways, his hands caging you against the wall, his lips brushing against your ear as he murmurs something filthy.

"You think you can tease me like that and get away with it? Oh, sweetheart, we’re far from done."

He doesn’t do subtle. His need is primal, immediate, and entirely consuming. If you’re within reach, you’re his—whether it’s in the privacy of his dorm or against a cold stone wall in the dungeons.

౨ৎ Possessive Chaos:

Mattheo doesn’t just want to own you—he needs to make sure everyone else knows it.

He leaves marks on purpose, smirking when you try to cover them up. "Don’t hide it, baby. Let them see who you belong to."

He’ll pull you onto his lap at parties, his hands gripping your thighs possessively, his dark eyes daring anyone to come close.

౨ৎ Praise Me, Baby:

Mattheo isn’t shy about telling you exactly how much he wants you. His words are rough, filthy, and laced with need, but they always leave you trembling.

"You’re a fucking goddess, you know that? Look at you, taking me so perfectly."

He thrives on your reactions—every gasp, every moan, every arch of your back. It’s his fuel, his addiction.

And if you praise him back? If you tell him he’s good, that he’s making you feel amazing? His restraint snaps. He becomes desperate, almost feral, to prove that he can give you everything you want and more.

౨ৎ Control Meets Chaos:

Mattheo loves being in control, but he’s also unpredictable. One moment, he’s guiding you with a firm, steady hand; the next, he’s pinning you down, his lips bruising yours as he loses himself in the heat of the moment.

He’s rough but never careless. Every grip, every bite, every growled "mine" is deliberate, a testament to just how much he adores you.

Push him too far, though—maybe tease him with a sly smile or brush your fingers against his neck when you know he can’t do anything about it—and you’ll unlock a side of him that’s both thrilling and terrifying.

"You want to play games, sweetheart? Fine. But don’t think for a second you’ll win."

౨ৎ The Edge of Obsession:

Mattheo isn’t just devoted—he’s obsessed. He memorizes every little thing about you—your favorite scent, the way your lips twitch when you’re amused, the soft sounds you make when he kisses that spot just below your ear.

He carries your favorite snacks in his bag, not because you asked, but because he noticed you skipped lunch one day.

౨ৎ Endurance King:

Mattheo doesn’t stop until you’re trembling, breathless, and begging for mercy. Even then, he’ll push just a little further, his lips curling into a wicked grin as he watches you fall apart beneath him.

"One more, baby. Just one more. You can do that for me, can’t you?"

And when you think you’ve reached your limit, he’ll hold you close, his voice soft and soothing as he helps you come back down.

౨ৎ Switching It Up:

Mattheo loves being in control, but when you take charge? Oh, it drives him wild. The second you push him onto the bed, straddle his hips, and demand that he behave, he’s putty in your hands.

"You’re gonna make me lose my fucking mind, baby."

Watching you take what you want from him—feeling your nails dig into his skin, hearing the way you gasp his name—it’s enough to make him come undone every single time.

౨ৎ The Vulnerable Side of Mattheo:

As intense and chaotic as he is, Mattheo has a softer side that he only shows to you. After the fire has burned out, he’ll hold you close, his lips brushing against your temple as he whispers things he’d never admit in the light of day.

"You’re everything to me, you know that? I’d burn the whole world down for you."

He loves running his fingers through your hair, tracing lazy patterns on your skin as he listens to your heartbeat. It’s in those quiet moments that you see the depth of his devotion—the way he’s completely, irreversibly yours.

౨ৎ Mattheo Riddle, The Lover You’ll Never Forget:

He’s fire and brimstone, chaos and passion, but beneath it all is a man who would do anything to make you feel loved, desired, and protected.

With Mattheo, every touch, every word, every moment is a whirlwind of intensity that leaves you craving more.

Because once you’ve been loved by Mattheo Riddle? No one else will ever compare.
