Second Chance is an ability in Kingdom Hearts, [[Kingdom Hearts II], and Kingdom Hearts 358/2 Days. The ability allows the player to survive a fatal blow with 1 HP so long as they have more than one remaining prior to the hit. In Kingdom Hearts II, there is a similar ability called Once More that allows Sora to survive a fatal combo with the same rules as Second Chance. Both abilities are considered necessary for defeating Sephiroth, because of his quick and easily fatal combos.
