Flood

The Flood is a type of Unversed featured in Kingdom Hearts Birth by Sleep, and is the most common form of Unversed. All Unversed are created from negative emotions, and the Flood represents irritation. It has a strong resemblance to the Shadow Heartless. Small, blue creatures, Floods are able to sink into the floor, becoming invincible, similar to the Shadow Heartless. As well, the Flood Unversed does not bear an Unversed insignia, being the only generic Unversed devoid of it.

Journal Entry
''Just because these foes like to dart around as they strike doesn't mean you should get antsy yourself. Lock on and let your keyblade do the talking. Careful, though: your attacks won't hit if the Floods have seeped into the ground.''

Design
A Flood is a sleek, humanoid creature with blue skin. Its arms and legs end in point and have no distinct digits. It has a triangular head with two long, jagged, lightning bolt-shaped antennae reminiscent of the Unversed symbol. Its red eyes are set in an angry expression and it moves in a jerking, twitchy motion. While most Floods are roughly the size of a Shadow Heartless, some in the Keyblade Graveyard are shown to be quite large. It is the only Unversed that does not have an Unversed emblem on its body.

Attacks
A Flood has a similar fighting style to a Shadow. It sinks into the ground to avoid damage and attacks enemies with its claws.

Strategy
A Flood, though very weak, can be quite a menace when in large groups. It is usually seen with larger Unversed, but a few hits will kill it easily. It is also possible to use magic in order to defeat this enemy. If it sinks into the ground, simply wait for it to surface before attacking.
