QuickStrike is an out-of-print collectible card game gaming system developed by Upper Deck for use in their games. This system made its initial debut in 2006. Compatibility All games making use of the QuickStrike system are compatible with one another, with the cards from different game sets able to be mixed together in a single deck. Specific tournaments or game formats may require that a deck consist of only cards from a single television series or film.

Allies - Cards with a purple border represent friends and companions who are providing assistance. Players also have a special Chamber card, which holds hidden signature moves for a character. At the appropriate points during play, a powerful signature move can be slid out of the Chamber and revealed. Zones Games are played utilizing a playmat, which provides each player with three colored zones. The green zone is the first line of defense, with the yellow zone being second, and the red zone being the last chance to successfully stop an attack. The zones are where players flip over cards to defend against attacks, as well as where stored sources of energy and allies are placed. When another player is attacking, the defending
