Sometimes, a person's spirit is just too corrupted to redeem. Maybe he committed despicable acts, maybe he became one of
The Heartless, maybe he just had extraordinarily bad luck. Regardless, there's simply no hope of redemption.
So, what do you do? Turn him into a baby!
Turning someone into an infant - mind, body and all - will essentially purify his/her spirit, and allow him to start over. Typically, the transformation is soon followed by one of the heroes (or at least a good person) adopting the newly made infant, and presumably raising him
right this time.
This can be undermined if the person who adopts him raises him to be evil, anyway.
Examples:
- Prince Cort, at the end of Legend Of Legaia, after which he is promptly adopted by Noa.
- The main character of Shadow Of The Colossus, during the final cutscene. (This is a rare example of not being any kind of redemption, as the hero of Shadow Of The Colossus is probably the only fully heroic character in the entire game. He was possessed by the god-like being that was guiding you through the game until that point at the end, though)
- Serge is purified in this way about two-thirds of the way through Chrono Cross, though he rapidly ages back to normal afterward.
- Blon Fel-Fotch Pasameer-Day Slitheen ("Margaret") in the Doctor Who episode "Boomtown".
- Hotaru Tomoe, alias Sailor Saturn, in Sailor Moon.
- Cassandra Nova in New X-Men.
- Mayuka in Tenchi Muyo: Daughter of Darkness.
- Borf, at the end of the obscure video game Space Ace.
- Michal in Mermaid Melody Pichi Pichi Pitch.
- Valgaav in The Slayers.
- Saffron in the final chapter of Ranma 1/2. As a phoenix, Saffron should be expected to reset to an egg after his defeat, though.
- One of the minor villains was redeemed in this way by Luna in Seiken Densetsu III.
- Inverted in Terranigma in which the villains do this to Ark once he's outlived his usefulness. However, upon gaining maturity again, he is 'reborn' as the hero destined to defeat Dark Gaia and complete another revolution of the cycle.
- Dream gives a Second Chance of this type to his former lover Nada in Neil Gaiman's The Sandman. Different from other examples because Nada was noble and virtuous, but had been made to suffer so much that Dream felt he could only make amends by giving her a chance at a happier life.
- As Kid Buu finally disintegrates into nothingness at the end of Dragon Ball Z, Goku wishes for his soul to be reincarnated so he's a better person. Indeed, Buu is reincarnated as Uub, a kindly and friendly boy from a poor village whom Goku meets again during the Tenkaichi Budokai. After a quick match to gauge Uub's powers, Goku takes him away and blows off the whole tournament, leaving on a years-long training mission to bring Uub up to speed.
- The bit about "raising him right this time" is explicitly stated in the Doctor Who story The Leisure Hive.
- Magneto, the famous X-Men villain, was changed from a mad world-conqueror into a more morally gray character this way, by his own creation, the "Ultimate Mutant". While he was later aged back to adulthood by a villain, complete with all his memories, his megalomania was now gone.
