Giga Chips

Giga Chips are the most powerful Battle Chips in the Mega Man Battle Network series. With this division being introduced in Mega Man Battle Network 3, they are all version-exclusive (except others mentioned in the list below), and cannot be traded. Players can only have one Giga Chip in their folder, and the only way to put more in is to use the Navi Customizer Program Giga Folder +1. They are known for being able to unleash outrageous damage and effects in battle, causing the reason for their limitation.

White Version

 * Navi Recycle: Brings back the Navi chip last used.
 * Forte/Bass: Bass appears and fires yellow shots rapidly down random rows. Can upgrade to Bass GS in an event or through hacking. Requires a Dark Hole to be present to use.
 * Serenade: Serenade appears and uses Holy Shock. Requires a Dark Hole to be present to use.
 * Proto/Alpha Arm Σ: Alpha appears to cover the field in electricity.
