Create a skull robot tank with 4 distinct arms, each hand holding a different weapon: a large industrial blade, a blaster, a menacing syringe, and a claw. The exterior metal is extra shiny silver grey, with inside cables and tech almost black. Smoke from the top is dark shaded. The skull face is positioned low and forward, similar to the attached references. Use retro stickers style with clean outline, compact proportions, and transparent background.emoji
