Cross System

The Cross System is a transformation system introduced in MegaMan Battle Network 6. It is similar in concept to the Soul Unison/DublSoul from previous games, in that MegaMan merges with another Navi (here called a Link Navi) but it does not use any chip sacrifices, and may last for the whole battle unless MegaMan is hit with an attack the Cross is weak to, in which case he takes double damage and loses the cross for the rest of the battle. EVERY cross now has a weakness, as 4 of the other attacking chip types (Wind, Sword, Break and Cursor) now have their own cycle of weaknesses (Wind->Cursor->Break->Sword->Wind).

Crosses here are more gimmicky and focus on status effects.

Dust Cross

 * Breaking element, weak to Cursor
 * B + Left will remove all obstacles. They can be fired using the regular Buster, dealing 200 damage.
