When Jason Todd was introduced as the second Robin in the early 1980s, the character did not exactly catch fire with the majority of fans. Some grudgingly accepted him as the replacement for Dick Grayson, who had moved on to become Nightwing. Others openly hated Jason, and the haters had *just* enough of a margin to vote for Jason's death in 1988.
During the seventeen years that Jason was dead, he remained a controversial and mostly reviled character (more so than when he was alive, oddly). Certainly, in 2003, fans were not clamoring for Jason's revival. When Jason *was* suddenly and unexpectedly revived in the mid-2000s, fans responded with an outcry of distaste.
But here we are, more than a decade later, and lo and behold...something UNTHINKABLE has happened: Jason Todd as the Red Hood is a POPULAR and INTEGRAL part of the Bat-Family. He has more fans today than he did during the first twenty years of his existence as a character in the DC Universe.
Would you consider Jason the most successful revived/rehabilitated character in comics history?
