Lanzer is a small purple creature with yellow markings on both its chest and its back. The enemy wears a shiny purple helmet resembling that of Sir Kibble, as well as purple shoes. Lanzer's hands are yellow, and do not appear to be attached to its body. The enemy grips a small metal trident with a wooden handle. Lanzer's luminous blue eyes shine through the visor of its helmet.
Lanzer bears a minor resemblance to Trident Knight.
Lanzer will either stand in place, or walk around its area. Upon nearing the player, Lanzer will attempt to skewer him/her with a quick thrust of its trident. Unlike regular Lanzers, the aforementioned Insect Lanzers may vary their walking speed.
Lanzer's name is derived from the word lancer, referencing its knight-like appearance.
