Melchior

Melchior the Magnificent is super mutant who resides in the fourth level of the Mariposa Military Base facility at the time of Fallout 2, in front of a steaming pit of radioactive goo.

Melchior was kidnapped from Redding by the Enclave - as witnessed by his young son, Melchior Junior - and taken to the Mariposa Military Base where he was turned into a mutant and has since taken leadership of the second generation of super mutants.

Whether he masterminded the rebellion against the Enclave slave masters is not known, but his magician skills were almost certainly used to accumulate and hide weapons, even though as a human his were limited to pulling a rats out of a hat.

One should approach Melchior with caution as he can summon horrific "pets" (deathclaws, geckos and the like) from the goo behind him (even posthumously).

He is armed with a Laser Rifle, and has a PPK12 Gauss Pistol in an ammo crate next to him.

Trivia
Melchior shares his name with one of the Three-Wise Men, Melchior (Gaspar and Belthasar were the others). He also shares his name with another NPC from the classic RPG Chrono Trigger, of which Melchior is the Guru of Life.
