 On November 1, 2008, Omega made his Pro Wrestling Guerrilla (PWG) debut at the 2008 Battle of Los Angeles, where he was defeated in the first round of the tournament by local talent Brandon Bonham.The next night, during a three-way tag team match in which Omega competed, he was Irish whipped into the ropes by Davey Richards, only for the force to snap the middle and bottom ropes, throwing Omega out of the ring.Three months later, Omega returned to the promotion at "Express Written Consent", where he was defeated by El Generico after senior referee Rick Knox hit him with a leaping clothesline after Knox grew tired tired of Omega abusing him.
