"Father" Thumb Dolmayan is the leader of the Rubicon Liberation Front, a survivor of the Fires of Ibis and a mech pilot. 50 years ago, he made Contact with a Coral wave-mutation called Seria. Together, they found out the truth of Coral. Seria tried to convince him to trigger a Coral Release to merge humanity and Coral, but Dolmayan, afraid of it destroying the human race, refused. Then the Fires happened. His mech, ASTGHIK, is black and red with outdated weapons, something the RLF use as well.
