Komabē is the second boss in Wario Blast: Featuring Bomberman!
Komabē will move in a spiral path across the room, starting from the top. If you cross its path (within 3 tiles of it) it will throw a boomerang at you. It is vulnerable until it retrieves the boomerang. It requires 3 hits to defeat.
Defeating Komabe rewards you with the Dash ability.
