Out of all of Batman's sidekicks, Jason Todd has probably had it the hardest. Originally Dick Grayson 2.0, Jason had acrobat parents whose deaths eventually led him to Batman and taking on the mantle of Robin. Despite a revamp thanks to the events of Crisis on Infinite Earths in the mid-80s, Jason still got the short-end of the stick.

With all of the blood and trauma his character has gone through, he has persevered as one of the most popular and complex members of the Bat-Family, always teetering the line between anti-hero and full-blown villain. But how much has he changed?

After Dick Grayson became Nightwing, Jason Todd became the second Robin, though who could tell? Most everything about Jason's backstory was a copy of Dick's own life before joining up with Batman. Post-Crisis, Jason became a street orphan who stole parts off of cars. Batman eventually took Jason under his wing but the boy had some real rage issues, another change to his original backstory. His new personality and the fact that he just wasn't Dick, caused fans to not like Jason all that much.

9 Death By Crowbar

Ever hate a character so much that when you get the chance to kill them off in the comics, you take it? In 1988, that's what fans did to Jason Todd. They voted for his demise and in A Death In The Family, The Joker beat him to death with a crowbar. It's one of the most brutal deaths in comic book history and even managed to sneak its way into the DCEU with homages to his death in Batman V Superman and Suicide Squad.

8 Punched Back Into The World Of The Living

Superboy-Prime punched the barrier of reality, causing a ripple through the DC universes and it was basically fair game. In the years after, many changes were made to different DC titles that were blamed on Superboy-Prime's altering of reality, the most significant of which is the resurrection of Jason Todd, who had been dead and buried for six months. After clawing his way out of his own grave, Jason kept things hush for years, not revealing himself until the time (and comic arc) was right.

7 Cared For By Talia Al Ghul

After rising from the dead, Jason was still heavily injured from The Joker's beating and was in a coma for some time. When he awoke, he had lost his memory and eventually found himself in the care of Batman's sometimes-flame, Talia al Ghul. When Talia pushes Jason into the Lazarus Pit, he is truly resurrected. With his mind and body fully healed and having gained some new mysterious abilities (super-strength and eternal youth among them), Jason set out to further train his mind and body.

6 Cosmopolitan Training, Just Like Batman

After his dip into the Lazarus Pit and learning that Batman had never avenged his death, Jason set out around the world to get first-rate training from the world's best fighters, just like Bruce Wayne had done before he became Batman.

What sets him apart from Bruce though is that Jason has no qualms about killing. So while he also trained to become a martial artist and an expert in hand-to-hand combat, he was also trained by the world's best assassins to be deadly and proficient in lethal weapons, which includes bombs.

5 Became The Red Hood

In the 2004-2006 arc known as Batman: Under The Hood, a character known as Red Hood (a mantle that was originally donned by The Joker himself) was making big moves in the Gotham criminal underground, and in Batman #638 it was finally revealed that Red Hood was in fact, Jason Todd. After his resurrection, Jason had changed dramatically from an angry sidekick to a killing machine, an anti-hero who wanted revenge on both The Joker and Batman. One for murdering him, and one for not seeking retribution.

4 Became A Gun-Toting Batman (For A Time)

In the aftermath of Final Crisis, where everyone believed Batman dead, Dick Grayson as Nightwing refused to become the next Batman in Bruce's absence, and so Jason decided to become the next Dark Knight in secret. Jason as Batman was a different kind of animal as he had an updated suit with a mouth plate and a lot of guns, essentially sullying the legacy of Batman by killing his enemies. Jason was eventually defeated by Dick Grayson, who became the next Batman until Bruce's return.

3 Batman's #1 Competition

After losing in The Battle for the Cowl, Jason decided to become Red Hood again, but this time as an alternative to Dick Grayson's Batman. By re-working his costume to resemble its original look (from when The Joker was Red Hood) and taking on his own sidekick, a traumatized girl called Scarlet, Red Hood cleaned up the streets in his own lethal, brutal way. Todd's vigilantism eventually catches up with him and he's arrested by Gordan and sent to Arkham Asylum and prison before escaping.

2 Donned The Alias Wingman

In Batman Incorporated, Batman asked Jason to become the second Wingman (the first Wingman was featured in Batmen of all Nations, a precursor organization to Incorporated) and to work with the global organization. Jason accepted the mantle of Wingman and took on Damian Wayne as his sidekick, Redbird.

One caveat that Batman had for Jason being the new Wingman was that he mustn't reveal his true identity to anyone, not even Damien. His time as Wingman didn't last, and he eventually returned to Red Hood.

1 New 52 and Rebirth With The Outlaws

In the New 52, Jason was still the Red Hood but with minute changes to his origin story. Mainly, he was still killed by The Joker, but under different circumstances, and Superboy-Prime was taken out of the equation of his resurrection. Jason and Batman finally came to good terms, with Jason wearing a red Bat sigil on his chest as he journeyed towards redemption. He formed a team with fellow anti-heroes Arsenal and Starfire (later replaced by Artemis and Bizarro), and they call themselves The Outlaws.
