Catack

Catack is a virus in the MegaMan Battle Network series that resemble a tank operated by a small shady figure. They appear in Battle Network 5 and 6.

Catacks slowly advance forwards one panel at a time. Each time they move forward, they will stop and fire their cannon. The blast will push MegaMan back if he is hit, but if it goes uninterupted, the blast will engulf the left-most column on MegaMan's side. Once Catack reaches MegaMan's side of the field, they will convert any panels they touch into enemey panels, but will stop advancing once they've reached the middle column. If two Catacks are present in battle, both will advance simultaneously, but only one will fire at a time.
