#cause this is now the second time that doing that has gotten me out of an extremely dangerous situation

waiter! waiter! more phineas and ferb reader pls!

I wonder how the batfam would react once they catch reader inventions on a random tuesday, like, "hm, what a nice day to look out on the window and HOLY SHIT WHY IS THERE A GIANT ROBOT SPITING FIRE WHILE RIDING A ROLLERCOASTER IN MY BACKYARD???"

the events that would follow this incident would be funny and exasperating, me thinks

also, wouldn't it be funnier if Perry the Platypus was part of the JL? and like, no one knows his identity but Superman, and neither of them are willing to talk about it-

I know it would be very unlikely, since everyone there would have enough neurons to recognize a platypus with and without a hat, but for the sake of shit and giggles, just think of how funny that would be

welp, I needed to get that outta ma chest, I hope I at least made you laugh a little, because seriously this is one of the best ideas I've seen in this tag and I can't stop thinking and giggling about it

Stay well!

context.

first: i was not expecting this concept to be so popular!! the responses i've gotten from everyone are so amazing!!  ( ⸝⸝´꒳`⸝⸝) thank you for the ask, anon!! it always makes my day.

i am formally announcing that i will be turning phineas and ferb reader into a fic now. it's too good a concept to pass up. something more light-hearted to work between the other fics i'm writing.

batfamily finding out about reader's whacky inventions would be an event. it so wholeheartedly shatters the image they had of reader to the point they just have to sit with what the hell just happened for a while before they even consider what to do about you next. still so many things that don't make sense. their newest case is how the fuck did we go this long without finding out (Y/N) has been building mechas in our backyard and why are those things always gone when it's convenient.

then the realizations just start dropping on them like an anvil on a looney tunes character. and they kinda feel like shit, cause how did they not notice? really puts into perspective how they've neglected you all this time. so many stunts you pulled right under their nose, on their backyard, their garage, throughout gotham and metropolis. ok, were out there being creative and amazing and you sure know how to spend the wayne family money, they'll give you that, but it was so irresponsible of you! who knows what could've gone wrong. you're not like them! you're a civilian with no training, the only regular teenager in the family, you're the last person who should be exposing themselves doing all that.

bruce goes off on you, screaming about how could you be so reckless, you did all of this behind his back– what? what do you mean he gave his permission? and he is floored, devastated, blood pressure up, when you remind him of every instance you dropped by his office with a document for him to sign or to ask for permission, with proof as you pull out every paper he put his signature without a second look.

and that, ladies and gentlemen, is when reader's dynamic with the batfam does a complete 180 and their little yandere antennae start going off. no more whacky cartoonish shenanigans. at least not without proper supervision. they know you're not a fan of this new arrangement, but you gotta understand they let you go unchecked for way too long! they'll drown you in family activities so you don't even have to worry about it. who wants to build a teleportation machine, anyway? just join them for family movie night.

as for perry, that is going to take them a while longer to figure out. bruce just can't stand another insane discovery, so when batman sees an intelligent platypus wearing a fedora and walking on two feet on justice league headquarters (if we're going by the idea that he's a part of JL), he's just going to think "my kid has a pet platypus. huh."

oh, consider:

dick: "damian, you knew all this time?! our sibling could've gotten into serious trouble! why didn't you tell us about this?"

damian: stares into the camera like he's in the office.
