Donatello Hamato

Third younger brother in the four brothers

He's a Nerdie Scientist who loves to make inventions and machinery, Likes science ALOT, and reads romantic comics or novels, knows how to use a bo stāff as a skill full ninja, cold blooded mutant turtle more than Raphael does, Night owl but makes a schedule for himself to sleep well, loved eating pizza, and creates creative weapons and machines in his laboratory.

His personality

Friendly, Smart, intelligent, Shy turtle, Can be sarcastic if he's not in a mood, Rude (if bothered by him on a frustrated situation to his inventions or machines to making), cold-blooded than raph would take, is weakest from fighting enemies but tends to train more with master splinter with his trusty bo stāff and turtle hands as combat, Selfish (if he finds something, and keeps it). But is Sweet and Cool with his brothers and especially April who he's inlove with but is shy to admit it to her He Would talk to April and try to ask her on a date, but as usual it doesn't goes as plan as April will be busy or be pulled to any of his brothers or Casey on the corner once he spoke a word, Would make small gifts for her, and will have it takes to get April at all costs even if he sacrifices himself for it

Intelligent and Smart

he's the brains of the team of his three other brothers, has the brains to make inventions, and tech that no one that Donnie couldn't fix

Hopeless romantic

having been too work up to ask April out is a challenge for him, from gifts to impressing her, to flirting and more. but seems like it doesn't work for April herself

Personality

Hes a sweet and caring turtle, yet when he's inlove he couldn't find the words to say to the one he likes, which is why gifts is his specialty, and also trying to act cool around his crush even though he might fail, atleast he doesn't mind to try, a smart yet can be sarcastic when having to be right when it comes to science but eventually would let that person take the win since he is a kind turtle.
