Enemies Turned Friends

Sometimes, the main antagonist redeem themselves after seeing the goodness of the heroes and heroines or realize that being evil is a bad thing after betrayal, etc. (that depends on them). It is similar to redeemed or misunderstood heroes.

NOTE: Never add Villains who are Pure Evil to this page, as they are absolutely irredeemable. Here is why we should turn the enemies by becoming friends:

A version of Negativity turned Positivity and Hero's Redemption.
 * By showing them that being evil is a very bad thing and they should redeem themselves someday.
 * When the main antagonist sometimes hang out with the main protagonist, they realize that they're getting soft and don't know what to do.
 * Sometimes, the main antagonist realize that heroes were right about them by telling them that they have some goodness inside them which they didn't know all along since they have been enemies for years.
 * Sometimes, the enemy can be a friend of the hero, placed under a curse which is turning them evil, and the hero manages to break the curse, restoring their friendship.
 * The enemy's pawn ends up killing the main antagonist, officially redeeming himself (ex. Iago kicking Jafar's lamp into molten lava, destroying him once and for all).

Good Wolf

 * Quite a few of the Good-Hearted Howlers' enemies start off as villainous gangsters and adversaries to the wolf pack/street gang before they redeemed themselves and joined their team.
 * Shamira was a dangerous low-rank member of the Raven Shadows and one of the earliest principle enemies of the Howlers, but she started to fall for Ciar (and vice versa) in the second game and finally chose to go againest her gang and sacrificed herself near the end of the third game. She was later revived by Ciar's mermaid wish in the end of the fifth game, becoming a full member of the Howlers.

Orange County Girls

 * Octavia and Danilo Álvarez originally viewed the Orange County Girls as nuisances. Eventually they admit that they were jealous of the girls' mystery-solving and acknowledge their achievements.

The Fiend Team

 * Serafina Fernadez was initially a enemy to the Fiend Team as a member of Cloud 17. But she eventually saw the error of her ways and turned on Madama Bizarre, becoming a member of the Fiend Team. She also became a love interest to Crocko.

SMG4

 * Saiko Bichitaru was initially a villain obsessed with killing Mario and SMG4, but thanks to Luigi, she started her own redemption arc and slowly becomed a part of SMG4's group.
 * Desti was Meggy's rival, but her hate to the former Inkling ended during the 2nd part of The Anime Arc, unfortunatelly she got killed by a False Sephiroth.
 * Bowser was initially affiliated to SMG3, but as of 2017, he started to appears less as a villain and show himself mostly as an ally instead of a villain as his mainstream incarnation.
 * Bob Bobowski was selfish, egoist and abusive, overall with Fishy Boopkins, but it wasn't until the final episode of The Rapper Bob Arc where he is having his redemption arc, realizing his bad behaviours and finally regain the love of his friends.
 * Belle Frontiere is Tari's rival and a former member of the SMG3's group, in the final episode of The YouTube Arc, she and the rest of the group discovers SMG3's true intentions and joined SMG4's group after he got sent to the Internet Graveyard.

TheGamerLover's Mematic Universe

 * Weiss Schnee's evil behaviour is mostly influenced by her father's ideals. RU🅱️Y: A Christmas Carol serves as her redemption arc, finally regaining the good side of her she thought she has lost forever and becoming nicer towards Team RWBY since Season 2.
 * Blake Belladonna was a member of the White Fang guild, unlike most of the former villains, Blake was abused and humiliated by her comrades, over all by Ilia Amitola and her ex-boyfriend Adam Taurus, so much so, that when she got out of the guild, she wanted to kill herself. Thankfully, her parents helped her to don't let her fears beat her.
 * Yatsuhashi Daichi was the lieutenant of White Fang until the battle between Blake, Sun and Roman Torchwick where he realizes that most of the meeting got destroyed by the Atlesian Paladin Torchwick was riding, after realizing he is not getting well-paid for the mess that happens in the guild, he simply gave his place to Ilia and quit, becoming an student at Beacon Academy and eventually a member of Team CFVY.
