Arn Etina was once the name of the final boss of Pluto, a black MOA found on Hades. Upon death there was a chance he would drop one of the components required to build Excalibur. Arn Etina's name was changed to Ambulas as of Update 6.0 (2013-01-29).
Despite being a MOA, Arn Etina used a human-like game picture for their transmissions. The game picture and appearance have since been repurposed for Darvo.
