A Floow (フロウス Furousu) is an enemy in Super Smash Bros. Brawl's Subspace Emissary mode which first appears in the Ruined Zoo level. It looks like a large black cloud with gray rectangles forming a humanoid shape and two small red eyes. Its trophy describes it as "a ghost patched with strips of darkness." A Floow's attack (some sort of scream) is a powerful combo attack that causes high damage and, and powerful knockback on the last hit. It is also possible for two Floows attacking at alternate times to trap a player. A particular annoyance of the Floow is its ability to steadily regain health, although it cannot move or attack while healing. Floows can be turned into a trophy with the use of a trophy stand, but precise aiming and timing may be required as the Floows float around. Floows are also completely immune to absorbable attacks; such attacks will simply vanish on contact and not do anything.
 Name origin
Its name is a corruption of the word "flow", which describes the way it moves.
 Damage taken
It is unknown why Floows take more damage than any other enemy; it can be inferred that it is related to its ability to self-regenerate and its long health bar.
 Trophy Description
An enemy that might be described as a ghost patched with strips of darkness. A Floow will float in the air and attack nastily from behind. Harboring pent-up resentment, a Floow's cries reveal one part sadness, one part madness. This especially hits home when gazing into its ghastly red eyes. After taking a certain amount of damage, a Floow will disappear.
