Seal Cannon (シールキャノン Seal Cannon?) is a tank-like enemy in the first two games from the Mega Man Zero series. They can be found on the floor, walls, and ceiling. They can be difficult to defeat, as they tend to move out of harm's way easily. In Mega Man Zero 2 they appear with a different color. Seal Cannon also appears in one of Zero's attacks in SNK vs. Capcom: SVC Chaos.
