Crystal Entity

Gem-Bodied Creatures are enemies that Wario faced during the events of Wario World. Wario first encounters one in Greenhorn Ruins, and they continue to appear in every subsequent level except Mirror Mansion. Gem-Bodied Creatures resemble huge crystals with a torso and head on top. They come in three colors: red, yellow, and blue. A Gem-Bodied Creature may show up by dropping in from the sky or rising up out of the ground. In either case, the Gem-Bodied Creature will form a barrier around her general area, forcing Wario to fight her before he can move on.

Gem-Bodied Creatures are completely immobile. Instead, they summon smaller Crystal Creatures to attack Wario. The Crystal Creatures come in two varieties: ground and flying. The ground ones wield weapons to hit Wario with and the flying ones can dive-bomb him. Wario can use them to damage and defeat the Gem-Bodied Creature; after knocking them out with some punches, he can throw them at the Gem-Bodied Creatures to hurt her. This is the only way to damage Gem-Bodied Creatures, as they are immune to Wario's regular attacks.

After being hit, Gem-Bodied Creatures retaliate in one of three ways, depending on their color. Red Gem-Bodied Creatures emit a laser beam that sweeps upward. Yellow ones fire multiple purple energy blasts in a straight line. Finally, blue Gem-Bodied Creatures fire three homing lasers at Wario. These attacks can also damage the Crystal Creatures.

Once a Gem-Bodied Creature has taken three hits and is dazed, Wario can then pick her up, which will immediately end the battle and remove the barrier. After that, any one of Wario's moves, or even simply dropping the Gem-Bodied Creature, will destroy her.

 * The "face" of the red Gem-Bodied Creature greatly resembles Mario's life counter in Super Mario Sunshine.
