Ramrog was a servant of the mutant Axi-Tun ruler Votan
, and a intergal part of his plan to destroy the Charter
and gain control of the galaxy. Ramrog began eliminating all life on planets by using a stolen Rigellian Planet-Lock to release giant planetoids onto planets causing countless deaths. Arcturus IV was the first planet to meet this violent fate. He was to use the Planet-Lock to destroy the Earth, but he failed due to the intervention of the Star Masters
. Ramrog later admitted that the failure to destroy the Earth was his fault. Votan commanded him to purify himself, which he did by self-destructing his ship, killing himself and all on-board.
