A Cymul (サイマル, Cymul) is an enemy in Super Smash Bros. Brawl's Subspace Emissary mode with a gray sphere, blue triangular eyes, and four reflector parts. It first appears in the Skyworld level and then appears 16 levels later, at The Research Facility II. It can reflect most projectiles, the lone exception being Trophy Stands. If a player goes near, it will spin its reflector parts wildly, attacking the opponent. The last hit will deal much more knockback than the other hits. A Cymul can also lap around a platform or just move vertically and horizontally.
First, notice the metallic sheen-- a specialized coating that allows the Cymul to reflect beams and other long-range attacks. The reflected attacks are said to be as strong as a Reflector's, so it's believed that the coating is based on Reflector technology. Coating aside, the four blades attached to its body cannot be neglected--they will slice and dice and slice.
