Basher, known as "Dogōn" (ドゴーン,"Dogōn"?) in Japan, is a virus from Mega Man Battle Network 3. It is a stationary virus that uses a scanner to scan along each column on the target's field. If it locks on a target, it jumps up and fires a tri-cannon that cracks the panels that get hit.
Basher is a white tri-cannon variant.
Smasher (ドギュラ Dogyura) is a yellow tri-cannon variant.
Trasher (ドガビーン Dogabīn) is a black tri-cannon variant.
