Under normal circumstances, whenever a character is hit by an attack that isn't a throw, their current action will be interrupted as they take the hit and receive damage. A character under the effect of armor, however, will still take damage from an attack, but their current action will not be interrupted. This means that if Player 2 with armor is in the middle of an attack animation, attacking them with Player 1 will not stop their attack, and will most likely result in Player 1 eating Player 2's attack. As previously mentioned, throws and other grabs will still be able to interrupt an Armored character. Armor is granted through the use of specific moves such as Scolipede's Steamroller, and will only last for the duration of that specific move.
