It will shoot laser waves on the floor at you and/or the Pikmin, which will count as electrical damage, so it shouldn't be too much of a problem if you have Yellow Pikmin and an upgraded suit for your captain. If the waves miss, they'll rebound against the mirrors on the arena walls for a bit before fading into thin air. At half health, it'll start shooting three waves at once which spread out in a scatter fashion, as well as a charge attack which bowls your Pikmin around like bowling pins, similar to one of Bowser's attacks from Super Mario 64. This Progg does not have a poison trail.
