Tim Drake is my favourite Robin and one of my favourite heroes in general. He's responsible for reinventing Robin as not only a competent aid to Batman but a superhero in his own right. He was the first Robin to run his own solo series. He's the reason Robin know wears a legit cool costume than whatever the hell he used to wear. He gave Robin a bo-staff and a fighting style separate from Batman's. There's a reason why Batman the Animated Series, and Teen Titans used Tim Drake for inspiration when writing Robin. He's considered to have potential to surpass Bruce in terms of intellect and detective skills. Hell Ra's Al Ghul even started calling him "Detective" the same way he calls Bruce.
But he keeps getting forgotten and screwed over. Batman The Animated Series mainly made him Jason Todd, and didn't give him his staff and fighting skills and not to mention what the Joker does to him. He appears in Young Justice Outsiders and looks cool and get's a few limelights but he's mainly a background character and doesn't really do anything. Arkham Robin looks cool and at least he's playable but once again he's shafted. He doesn't do anything in City and in Knight he's made Dick Grayson 2.0 and doesn't do anything either. He didn't even show up in the New 52 based DC animated movies. All he gets in Injustice 2 is a cameo and that's not even mentioning what the comics do to him.
He's a character with a lot of potential that is being wasted and shafted. I heard he now goes by Drake which is just dumb and not to mention his new costume is pretty ugly. He needs a better spotlight.
