A Glice.

The Glice is an enemy in Super Smash Bros. Brawl's Subspace Emissary mode. It appears as a round machine with a central eye, and attacks by emitting ice. It can roll around the stage and climb up walls. It also has two other forms; one is Glunder, who releases thunder instead of ice, and Glire, who releases fire.

Trophy Description

A soldier in the Subspace Army that moves easily up walls and slopes alike. Like a Glire, it sheds its outer shells to attack, but it releases waves of bitter cold instead of fire. This attack will freeze the player in a lump of ice if it hits. To escape quickly, move the Control Stick rapidly back and forth. This combative enemy will attack whenever it can.
