Space Pirates Trooper: Zebesian
Super Metroid Space Pirate, unlike my previous one, this I must guest, had lighter armor, since the other require at least missiles or other beam upgrades, while this fellas can sucumb to basic power beam shots (not even charged)
I know that both can climb wall, but I wanted to give him some advantage, poor weak guys.
