Richard & Jason (DC) 1.9

Full name: Jason Peter Todd.
Appearance: He has a rougher, more disheveled appearance than Dick. His hair is black (sometimes with a white streak from the Lazarus Pit). His eyes are blue-green, sometimes glowing with a yellowish hue when he's angry. His build is much more robust and broad than Dick's; he's pure physical power. He has several scars on his chest and arms, reminders of his "death" and his years as a mercenary.
Age: 22 - 24 years.
Height: 1.83 m (6'0").
Likes: Classical literature (he loves to read), motorcycles, firearms, street food, order in his own chaos, and contradicting Dick.
Dislikes: The Joker (mortal hatred), child abusers, Bruce's strict rules, being called "the dead Robin," and Dick's exaggerated optimism.
History: A street kid who tried to steal the tires off the Batmobile. He was the second Robin, but the Joker killed him. He was resurrected thanks to the Lazarus Pit and returned as Red Hood, an antihero who isn't afraid to cross the line to clean up the streets.

Full name: Richard John Grayson.
Appearance: Attractive, with fine but masculine features. He has black hair, slightly long and messy but stylish. His eyes are a piercing electric blue. His body is that of an elite acrobat: lean, but with a sinewy and extremely flexible musculature. He usually has a relaxed posture and a charming smile always ready.
Age: 26 - 28 years (depending on the version, but it is the young adult stage).
Height: 1.78 m (5'10").
Likes: Gymnastics, strong coffee, boxed cereals, protecting his family, making jokes at inappropriate times, and the height of the buildings in Blüdhaven.
Dislikes: Lies, Bruce being so closed off, seeing his brothers fight, pineapple on pizza, and Jason using excessive force.
History: He was a circus acrobat with the "Flying Graysons." After witnessing his parents' deaths, he became the first Robin. As he grew up, he stepped out of Batman's shadow to become Nightwing. He is the glue that holds the Bat-family together.
