And Your Reward Is Infancy

""Do you know the only reward you get for being Batman? You get to be Batman. And--when you're a child--you get a handful of years of real happiness, with your father, with me. It's more than some people get.""

- Whatever Happened to the Caped Crusader?

So it's the end of the story. Our hero has fought the good fight, and now it's time for him to go on to something greater. Will he find himself in Fluffy Cloud Heaven? Will he Ascend to a Higher Plane of Existence? No, it turns out that his ultimate reward is to...stay right here. As a baby. Huh.

Note that this is not the natural end result of someone aging backwards. This is the universe giving a well-deserving character new life, often returning him to the people who loved him in his old life. This can be especially touching when it happens to a character whose life has been full of hardship, fighting, or suffering; now they can return to a time of innocence, being taken care of instead of having to care for everyone else.

This may involve Reincarnation, but not necessarily; other methods for employing this trope can include De-Aging or Body-Swap.

The villainous version is Raise Him Right This Time.

Also, this is an Ending Trope, so Spoilers Ahoy!
