Dark Chip

Dark Chips are powerful BattleChips that increase a NetNavi's strength but destroy its connection with its NetOp and turn the Navi into a Darklord. ProtoMan.EXE turned evil in episode 27 of Axess after Chaud slotted in a Dark Chip. Darkloids use these chips to survive. They start out using them to become more powerful, but soon become addicted and need them. After a while of addiction it starts to corrupt their data, until eventually they become so corrupted that they are deleted. In the anime Dr. Hikari says that the Dark Chips are a type of chip which trades a Navi's soul for power. They were created by Dr. Regal.
