Glice's name is a combination of the words glare, referring to its wide open eyes, and ice, referring to its freezing attack.
The Glice debuted in Brawl's Subspace Emissary. It looks like a medium-sized black tire with an eye in the middle. It moves around the stage by rolling along floors, walls, and ceilings, although it will be knocked down by attacks. When approached by a Smasher, Glices will stop and release an ice attack which freezes the character. While a player would instinctively try to break free quickly, a Glice will not attack a frozen character, and getting out of the ice as fast as possible usually just allows the Glice to attack again. Glices near pits can be very dangerous, as they can cause frozen players to fall down and be KO'd at low damage.
Glices return as enemies, keeping their Brawl behavior.
