General Dynamics

Can I request rotmnt with anger issues teen!reader (gn, 15-16) who has difficulty with expressing that they see the turtles as their sibling figure? They don't wanna admit on how they see the turtles cuz if they said that the reader would be embarrassed due to how they were treated by their bio siblings about it so they just don't say anything, only that they are just friends.

A/N: Of course! Here's a set of headcanons for the Rise of the Teenage Mutant Ninja Turtles (ROTTMNT) with an angry, reserved teen reader who secretly sees the turtles as sibling figures but has difficulty expressing it. I HOPE YOU ENJOY IT!!

General Dynamics

The Turtles’ Initial Perception: At first, the turtles assume you’re just a moody, tough teenager who prefers to keep things casual. They respect your boundaries but are curious about the walls you’ve built around yourself

Your Struggles: You often lash out when things get too emotional or personal, fearing vulnerability might lead to mockery or rejection, like what you experienced with your biological siblings.

Silent Acts of Care: Despite your reluctance to express your feelings, you show you care in subtle ways—fixing things they break, grabbing their favorite snacks, or patching up their gear without being asked.

Individual Turtle Dynamics

Leonardo:

Leo teases you constantly, but he’s careful not to push too far when he senses you’re genuinely upset.

He makes lighthearted jokes about you being “the angsty middle sibling” to see if you’ll slip up and admit you see them as family.

When you’re overwhelmed, Leo offers distractions rather than deep talks—movies, video games, or spontaneous rooftop hangouts.

Raphael

Raph is incredibly protective of you, even if he doesn’t fully understand your emotional struggles. He sees you as part of the team, even if you insist you’re just “friends.”

He’s the first to notice your hidden acts of kindness, like repairing his punching bag or leaving protein bars in his gym bag.

During heated moments, Raph is the one to remind you it’s okay to be angry, but he also encourages you to channel it productively—sparring matches become your shared thing.

Donatello

Donnie appreciates how you quietly help out with his experiments or organize his tools when he’s too busy to do it himself. He doesn’t say it outright, but he considers it your way of bonding.

He’s great at giving you space when you need it but will also deliver blunt truths if he thinks you’re being too hard on yourself.

Donnie surprises you by creating small gadgets that help manage your anger—like stress-relief tools or a punching dummy that fights back (lightly).

Michelangelo

Mikey makes it his mission to break through your emotional barriers with kindness and persistence.

He often pulls you into group activities like cooking, painting, or prank wars, subtly reminding you that you’re part of their “family unit.”

Mikey is the one who comforts you during rare moments of vulnerability, assuring you that it’s okay to care about them without fear of rejection.

The turtles, being who they are, would likely accept you with open arms, helping you work through your anger and fears while showing you that family isn’t about blood—it’s about love and loyalty.
