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.

Other

 * Chaos Lord: Nebula Grey appears out of a portal of darkness and turn into Bass to fling a huge Chaos Nightmare that hits in a 3x3 fashion. Unblockable, and cracks all affected panels. Available only in BN5's DS remake.

Other Chips

 * Gregar: Gregar appears and uses Gospel Breath (the fire is purple, like that of Gospel's, when it should have been red) while rocks fall down on the enemy area. Japanese-exclusive.
 * Falzar: Falzar's feathers rain on the field, then appears to use a Falzar Tornado. Japanese-exclusive.
