Jason Todd
Why do I like Jason Todd as an anti-hero?
But let us first talk about his life and how he became red hood.
All his childhood lived and grew as a thief, one day he catches a gang meeting as he goes in to steal spare parts of a big machine. He is then caught by Batman sneaking behind batmobile. But he tells him about the meeting as Batman leaves him. Penguin is caught and put in Blackgate for good.
Bruce reads through his profile very briefly and then adopts him with Dick gone to Bludhaven Jason fills his void. With his arrogant, steadfast and ruthless nature. He becomes the second Robin.
