6) He’s Directly Responsible For Jason Todd Becoming Robin
Dick Grayson’s origins as an orphaned circus acrobat are widely known by superhero fans. But did you know that the second Robin, Jason Todd, shares basically an identical backstory? This time around, though, it was Killer Croc who was responsible…
As well Croc, Batman #357 also saw the debut of Jason Todd. When Croc is involved in some shifty dealings with a circus, Dick Grayson asks some acrobat pals of his to keep an eye on him. Unfortunately, Trina and Joseph Todd are brutally murdered by the monster when he realizes he’s being watched.
Fuelled by his hatred for Croc, Todd joins Batman in his fight against Gotham’s underwold and becomes Boy Wonder Mark Two. Well, until a fateful encounter with the Joker, that is. But that’s a story for another time.
