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).
