Description
Warrock, known as Omega-Xis outside Japan, is one of the few survivors from the destroyed Planet AM. He fled incognito to Planet FM before stealing the powerful Andromeda Key sought by FM-ians and escaping to Earth. There, he encountered Geo Stelar, a young boy mourning his father Kelvin's disappearance. Omega-Xis leveraged information about Kelvin to take residence within Geo's Transer device.

He possesses a brash, headstrong, and loud personality, frequently clashing with Geo's reserved nature. Their partnership fosters mutual growth: Omega-Xis learns the value of friendship and courage, while Geo gains resilience. In the anime, Omega-Xis initially shows greater reluctance to help others, often questioning Geo's insistence on aiding strangers and avoiding battles he deems unwinnable, like against Gemini Spark. He exhibits more childish tendencies, pestering Geo out of boredom, and frequently teases Geo about romantic interests like Sonia and Luna.

Their core relationship involves Electromagnetic Wave Change (EM Wave Change), merging their beings to form the EM Wave Human Mega Man and combat threats within the EM Wave World. Their initial alliance targets FM-ians pursuing the Andromeda Key and uncovering the truth behind Kelvin Stelar's disappearance. Following a defeat by Gemini Spark that caused Geo to sever his BrotherBands, a temporary separation occurred. Omega-Xis rejoined Geo after witnessing his renewed resolve. Their journey culminated in confronting FM King Cepheus in space, where Omega-Xis revealed his AM-ian heritage and exposed Gemini Spark's manipulation of Cepheus to destroy Planet AM. This reconciliation spared Cepheus and established peace.

During the *Tribe* storyline, Omega-Xis accidentally swallowed the Sword of Zerker (OOPArt) in a museum skirmish, causing intermittent pain from residual EM spirits. Despite this, he aided Geo in battling UMAs and Dr. Vega's forces. Dark Phantom later forcibly removed the OOPArt, though residual power allowed temporary use of the Thunder Zerker and Tribe King forms to defeat the revived Mu continent and Le Mu.

Other narrative elements include his historical rivalry with FM-ian criminals Virgo and Corvus, who bullied him on Planet FM. In *Mega Man Star Force 3*, he developed a one-sided rivalry with Acid, feeling overshadowed by Acid's competence and reacting jealously to Acid's interactions with Geo. He also expressed irritation toward cloned versions of himself during an attack on WAZA headquarters.

Beyond the main series, Omega-Xis appears in *Rockman.EXE Operate Shooting Star*, traveling back in time with Geo to the events of the first *Mega Man Battle Network* game. He features in a Japanese-exclusive *Lunar Knights* side quest, classified as a Terrennial.
