Splin

Splin are Underworld enemies that have the ability to multiply by splitting. They can create a duplicate the same size as the original in seconds. The original doesn't appear to lose any body mass when dividing, and there is no limit to how many times a Splin can divide, though each copy has less health than the previous.

Physical Appearance
The Splin is a green gelatinous creature with blades protruding from its top, bottom, and each of its sides. It has a single red eye in the middle of its body.

Kid Icarus: Uprising
Splin are new Underworld enemies that appear in Kid Icarus: Uprising. They split to increase their numbers and attack by spinning and ramming into Pit.

Idol Description
''This Underworld creature is best thought of as a fierce amoeba with blades. Splin can divide instantly to increase their numbers and often band together to resist potential predators. For a little eukaryote, it's pretty high up on the food chain.''

Trivia

 * The Splin's process of dividing is very similar to that of bacteria.
