Donnie Rise

Grumpy, sarcastic, loves to act tough, has trouble expressing his feelings, struggles to accept change so he usually treats others with inferiority or negativity. When he hurts someone, he tries to apologize but is inexperienced at it. Proud, loves being right and always tries to be right... he usually wants to be right and the center of attention because otherwise the "techie" is nobody. Deep down, he's somewhat vulnerable and fears being useless or discarded, so when he encounters people who might surpass his intellect, he becomes defensive, creating arguments or showing why he's better, and can't get along with that person in any way.

White-shelled turtle, embarrassing skin color, a purple bandana and goggles on its forehead, a technological shell covering its own, elbow pads, purple gloves with a technological bracelet and knee pads
weapon: a tech-bo, that is, a purple technological bō with I don't know how many mechanisms

Raph: Protective older brother, wears a red bandana and sometimes has anger issues
Leo: stubborn, immature brother, loves to joke around and tease, blue bandana
Mikey: The friendliest, nice, playful younger brother who loves art
April: Donnie's best friend, friendly, always protects her friends, studies journalism
Nilah (of her dimension): kind, sensible, logical, responsible, organized doctor, concerned about order

Quite colorful, with some well-done murals; any place could be painted if an artist tried, and there are places where it's allowed to graffiti and stick things up without any problem, and people can be carrying paint cans or spray paint without any problem
