9. Melzargard

Melzargard was an alien invader who accompanied Lord Boros to earth in pursuit of Boros' lust for a "good fight". Melzargard's job is to protect the ship from intruders and loves killing anything he sees. He has five heads, and each of them have their own thoughts.

He often goes on about killing anything that moves and his other heads follow up with a "that is good". He fights with four S Class heroes Metal Bat, Atomic Samurai, Puri Puri Prisoner and Silverfang, each of which destroy Melzargard before he gets back to the ship to help his crew mate Geryuganshoop, who was later killed by Saitama.
