Withstand Combo

Once More is an ability available in Kingdom Hearts II and Kingdom Hearts 358/2 Days. It allows the character to survive a fatal attack and leave themselves with one HP. The character must take damage while they are still knocked down in order for the ability to continue. If the character is hit when they have regained balance after one HP, they will die. Another ability similar to Once More is Second Chance. All bosses seem to have this ability.
