A Subspace Army member who is mostly cloud but also reveals mechanical parts, like electrodes and batteries. In most cases, a Spaak is white and fires lightning, but it turns into a dark cloud after taking damage and chases you with fast lightning strikes. Its weak point is the battery on its back--attacking that should make it pretty easy to take down.
