° First of all, the difference between universes isn't so obvious in the beginning, but you notice you can't do a lot of things like expecting people to not notice when important stuff happens. Humans are actually sapient beings here
° Secondly, matter your actual age doesn't matter, you're a child in comparison to the turtles.
° Millenials vs Gen Z energy kind of relationship
° 2003 Turtles have their fair exchange of weird bullshit, from dimensional travel to alternative timelines to getting yeeted to the future by April & Casey's Great Grandchild. Handling you should be an easy challenge, right?
° You're similar to the Turtle Power dudes from the 80's in terms of getting on their nerves. But also, aren't. They can't exactly get mad at you for acting like your age.
° 03!Leo feels responsible for your well-being. He tries to keep you on check as long as he can. Which is so goddamn hard when you keep jumping so recklessly into dangerous situations! No! It doesn't matter that you have cartoon invulnerablity in your universe! Now, get into that corner and reflect on your actions!
° His brothers definitely tease him about Mother-hen Leo being back on the job° You laugh at his lame dad jokes, making his brothers groan.
° In the end, he's not so different to your Leo
° The first one to actually befriend you is Mikey. As always. He might not have a passive-aggressive doctor persona as your own Mikey, but as a menace of society with a list of charges larger than your Donnie, he's a bad influence on you.
° He'll enable any quirk, violent, rule breaking, crime fighting tendencies that you have
° To him, you're a pure white canva ready to be corrupted into the perfect minion (affectionate)
° He might—no, he will drag you to patrol the city as Turtle Titan, with you being whatever superhero persona you decide to be, or he gets you the Green Mantle suit that was from Raphael, since his brother would punch him before even trying. He's definitely going to show you off to Silver Sentry and the rest of the Justice Force
° Don't worry, his brothers are going to track you both before things take a serious turn. Prepare yourself to be scolded to oblivion when you get to the lair
° Unpopular of what a lot of people may think, Raphael has a weak spot for kids, the elderly and animals. You shouldn't be crime fighting. You should be having a normal life. He might act grumpy, but he cares a lot.
° Raphael just doesn't want to see you turn out like them, okay? You're a nice kid, an innocent kid. He hopes you enjoy your childhood as you can.
° He gets startled when you try to get a ride on his shell the first few times since bad habits die hard. It's not your fault. It is actually a reflex to just climb on your Raph's shell.
° After a few weeks, he's got no problem when you shove his head down to climb on top of him. Do as you want, but don't expect the experience to be the same
° The only things that made a resemblance of this Donatello and yours is that they both wear purple
° You actually go around his lab searching for something potentially dangerous, like a death ray or the next sentient toaster that tries to kill Leo for blowing it up
° Donatello is actually fascinated with the mystic from your world, wishing to study it and maybe learn how to use it. He's a turtle of science, after all
° Until you found him passed out in front of his workbench and had to call Raph or Mikey to force him to sleep
• You didn't exactly call Leo because you recall the bastard actually challenging your Donnie who can spend more time without sleep
• Your Leo wins, by the way. He totally sabotages Rise!Donnie
° Or you might try dragging him yourself. A battle shell made of titanium is quite heavy, so you have practice
° You might not have the same relationship you had with Casey and April, with them being both teenagers in your world, but you still like them
° What do you mean there's TWO CASEYS IN YOUR WORLD!?!?!?
° You give 03!Splinter a side eye every time you find him meditating or training the turtles. Why he's so.... Dignified?
° At some point, Splinter asks you to come meditate with him. Meditation is boring, but maybe you could use this to get to know more the rat.
• You end up falling asleep and waking up on the couch with a blanket covering you. THE MYSTERIOUS GHOST THAT TUG YOU IN YOUR BED IS BACK!!!
° WHAT DO YOU MEAN LOU JITSU AND JUPITER JIM DON'T EXIST!!
° Michelangelo introduces you to Jackie Chan and Star Wars after that. You download all the movies to your phone to show them to the boys when you get back home. You won't admit it, but this Jackie guy is funnier than Lou Jitsu has ever been
° You end up introducing them to Jupiter Jim and Lou Jitsu, kind of a little impressed of how many sequels they have
• Splinter is looking at Lou Jitsu with longing. Instead of being disappointed like how many people may think, 03!Splinter is more than happy knowing that his master chased after his passion (would make weird expressions if actress Tang Shen is on screen)
° You finally show them videos from your turtles, more specifically, some from the Lair Games. This got some mixed reactions
° Most of the turtles, aka Mikey and Raph, are teasing Leo about his counterpart, no, they don't hate Rise!Leo, in fact is kind of refreshing meeting this carefree version of their oldest brother, but Raph cringes when you mention he's twins with Donnie. He's supposed to be Donnie's twin, not mister Stick Up To His Ass!
° Rise!Raph got a bunch of laughs and coos because, just look at him, he's so spiky but so softie under that! Donny's trying to act natural, but Rise!Raph is way too similar to the time he double mutated. They'll put somber expressions if Savage Raph is brought to the conversation.
° Most of them get baffled when Rise!Donnie hisses on the screen or is randomly violent. I mean, 03!Donny can get a little violent sometimes, like the time he chased 03!Raph with a hammer for destroyed his inventions, but Rise!Donnie experiments on his brothers on daily basis. Don't let Donny know that.
• "It's that a statue made of reinforced titanium!?!?!?!"
• Were his counterpart even got that!?!
• 03!Donny, you stole a helicopter from the government. You're not so innocent
° Why is smaller Mikey so calm and cute?? Why he's—Nevermind, was the line of thought of being presented to Doctor Delicate Touch
° The haunting looks the give to you when you reveal that only Raph was fifteen when facing Shredder
° They keep quiet for a whike when you put Demon and Shredder together
° How can you be so calm about everything????
° They want you to go to a therapist
° Them??? They're fine! Perfectly fine!! Besides, it's not like any therapist is going to not scream when they land their eyes on them
° If you're human, that's perfectly fine! You can walk the streets of New York without problems, but if you're seen with April or Casey, you may attract the attention of certain enemies.
° If you're a mutant, you're not allowed to go to the surface until the night has fallen, and only if you're with one of them. It's not that they don't trust you to take care of yourself, but out there exist monsters with human skin like agent Bishop that won't doubt experimenting on you
° If you're a Yokai, you're probably fed up with the baby treatment. Like, please! You're not 89 anymore. You're practically a grown-up! They may not suspect anything because of your cloaking brooch, but when you take it off, underneath is either a cute yokai or an eldritch abomination. There's no in between. You definitely have some rad mystic powers that can counter any minor villain that may try his luck with you.
° Pray the villains you're not Post Rise Movie, because in that case YOU'RE THE ONE that's going to be overprotective of the turtles, having training your mystics until tiring you out, and isn't that sad? You're scared for them that something or someone might hurt them. And they've been hurt in the past, a lot. If an enemy tries to cross you, they may want to watch their backs, because you may not have the experience, but you survived the Krang Invasion, you can do some damage.
° The Earth Protection Force and the Foot Clan better get their noses on their own business because if something happens to you because of them, not only they're going to answer to the 2003 turtles, but also a group of interdimensipnal turtles with superpowers, and one of those can throw buildings
