Anti Chips

"Anti Chips" and "Anti Cards" are a family of trap Battle Chips and Battle Cards in the Mega Man Battle Network and Mega Man Star Force video game series respectively. They also appear in the MegaMan NT Warrior anime series. When used in the video games, Anti Chips freezes time and “????” will appear on the top left hand corner of the user’s screen (in PvP, it will appear on the top right hand corner if the player’s opponent uses one). When the enemy uses the chip or element that the trap was set for, it prevents them from using the chip or element and counters it.

In the Mega Man Star Force series, AntiSwrd returns, and ElemTrap, AntiRecv, and AntiNavi return as Spirit Fury, Poison Apple, and Double Cross. A new Anti Card called Giga Mine also appears, which counters Giga Cards.
