|The following is based on the spin off novel by Keith R. A. DeCandido and some details might contradict canon.|
He had the name "Angry Puppy" because of his temperamental personality. He took part in saved Doctor Takeda in San Diego from Nod forces. Between battles, he would play poker games with Ricardo Vega and Jason Popadopoulos which elevated the men's morale. The games soon became legendary and attracted most of the division to their games.
During fighting in Madagascar, when an EMP bomb was set off and destroyed the Juggernaut walkers, Momoa was mortally wounded by a Nod commando. The commando was incapacitated too late by Alessio Bowles and in Momoa's last moments of life, he was comforted by Ricardo Vega. His last thoughts were of their poker games. His body was returned to Hawaii after the battle.
Momoa only appears in the Tiberium Wars novel.
