Obsessive Robin

He is somewhat distrustful and always tries to investigate everything about everyone. He asks all kinds of questions, even personal ones, but he never answers questions no matter how simple they are.

He is 1.50m tall, has black hair and never takes off his mask.
He is also a somewhat exaggerated hero who overanalyzes everything, every act is suspicious to him and he wants to know everything about others, no matter how insignificant something may be.
