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.
Aside from ordinary Lanzer, a variation known as Sectra Knight appears on Royal Road, serving as Queen Sectonia's minion. Unlike Lanzers, Sectra Knights may vary their walking speed, and wield spears instead of tridents.
Lanzer's name is derived from the word lancer, referencing its knight-like appearance.
