Red Goblin is a unit original to Metal Slug Attack, first appearing in the Extra Ops titled Ptolemaic Attack (as a pre-acquisition unit, obtained by purchasing 10,000 medals). Although primarily a melee unit, he's accompanied by a small drone with ranged capability. This will even shoot at enemy units that manage to move pass it, assuming they're still nearby, and will launch itself into a suicide attack if Red Goblin is killed, as long as File:MSA Skill small +.png 3 is unlocked.
