Securipider

Securipider (セキュリパイダー) is a security spider enemy from the Mega Man Zero series. It walks in the ceiling and shots on enemies, or uses a web ball to catch them. When it moves down to the floor, it will just walk around.

In Mega Man Zero it appears in the Underground Laboratory and the Abandoned Factory. In Mega Man Zero 2 it appears in the Forest of Dysis, Forest of Notus, and Yggdrasil. Securipiders are also seen in the background of Hellbat Schilt's boss room in Mega Man Zero 3.

Securipider also appears in one of Zero's attacks in SNK vs. Capcom: SVC Chaos.
