The Spaak (スパー, Spar) is a common enemy in Super Smash Bros. Brawl's Subspace Emissary, depicted as a cloud with facial features, a battery on its back, and eight Tesla Coils. A Spaak starts off as a white cloud, which attacks by shooting slow electric spheres with low knockback while remaining stationary during the attack. After taking a certain amount of damage, it turns into a black storm cloud, which shoots out fast lightning beams with high knockback, while at the same time moving more evasively. Both attacks can be reflected, countered, or absorbed. The battery on its back is its weak point, and attacking it will result in double damage. Its normal mode is shown on the trophy, regardless of which form was caught via the Trophy Stand.
Its name is a corruption of the word "spark", which references its appearance and electric attacks.
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.
