Centurion (センチュリオン,senchurion?) was a mutant centipede which lived in the Arklay Mountains. As Umbrella's investigation team failed to find evidence of Dr. James Marcus having performed research on centipedes, Centurion is believed to have been a freak accident resulting from a centipede consuming contaminated materials within Umbrella's executive training center.[excerpt 1] The Centurion was killed by former Marine 2Lt. Billy Coen, when it tried to eat S.T.A.R.S. officer Rebecca Chambers.
