Who does sidekick Robin grow up to be?

Robin, the sidekick of Batman, has been portrayed by many different characters throughout the years. Therefore, the answer depends on which Robin you are referring to:

* Dick Grayson: The original Robin, he eventually becomes Nightwing, a superhero in his own right.

* Jason Todd: After his death and resurrection, he becomes Red Hood, a vigilante with morally ambiguous methods.

* Tim Drake: He continues to be Robin for a long time and eventually takes on the mantle of Red Robin.

* Stephanie Brown: After briefly being Robin, she becomes Spoiler and later Batgirl.

* Damian Wayne: He remains Robin for a while but eventually becomes Robin and Batman after Bruce Wayne's retirement.

So, while the path for each Robin varies, they all grow up to be heroes in their own right.
