Z2 Helcon Tanker

Z2 Helcon tankers (singular Z2 Helcon tanker) or Z2s (singular Z2) are hulkingly bulky matons that virtually have the same head design as Z1s besides the fact that they have hair-like "spikes" jetting out from the top's disk, where they go towards the back of the head. Unlike Z1s, they are large and almost twice as big as them, and their right arm has a built-in (and hulking like their form) gun that has two modes: one where it acts like a machine gun, shooting small but fast-moving green bulbous projectiles ("gunner mode"), whilst the other mode shoots a slightly slow-moving large green orb that deals great damage ("orb mode"). Z2s' legs are thick and could be described as stubby, but do not greatly limit their stride (for their mass does). They cannot even truely jump or hop.
