Geo Stelar
It’s been three years since Geo’s father left for work at the space station and never returned. Three years spent moping around the house, refusing to attend school, and showing little interest in making friends. No, losing a father wasn’t easy for a fifth grader like Geo, but his life is about to change, thanks to a gift from his father’s coworker. Indeed, a whole new world is about to open up.
Thanks to the Visualizer—and his mother insisting he go outside—Geo uncovers an invisible world around him, the EM Wave World. His guide to this world is an alien FM-ian named Omega-Xis. Not only does “Mega” claim to know Geo’s father, but he’s also going to fuse with Geo, imbuing him with the power to become Mega Man. Lured by the promise of learning about his father (a quest that reaches its conclusion in Mega Man Star Force 3), Geo discovers that he’s not the only troubled child in the world—and that the world is far more interesting with friends. It is through those newfound friendships that Geo embarks on the story lines of the sequels.
Omega-Xis
A fugitive alien who fled the FM Planet after stealing the Andromeda Key (or so he says), Omega-Xis is a gruff creation of electromagnetic waves, only visible thanks to the Visualizer Geo receives as a gift. Mega, as he likes to be called, is determined to keep the Andromeda Key out of the hands of the FM King and fuses with Geo to increase his odds. When not battling FM-ians and viruses, Mega takes to studying human behavior...and he’s not sure he likes what he sees.
Sonia Strumm
Popular at school, outgoing, and never one to let a comment go unsaid, rock star Sonia Strumm is everything Geo isn’t. But their differences pale in comparison to the one thing they have in common: Sonia, too, has lost a parent at an early age. Sparked by this unfortunate circumstance, the two forge a lasting friendship that carries them through the trilogy. Sonia routinely invites Geo out on dates and even shows signs of jealousy when he’s around other girls.
Gemini Spark
Gemini Spark is the EM Wave Change form of Patrick Sprigs and his alter-ego Rey Sprigs. Hailing from Planet FM, Gemini traveled to Earth in pursuit of the Andromeda Key, putting him at odds with Omega-Xis and Geo. By fusing with Patrick, he formed a BrotherBand with Geo. Thanks to Patrick’s split personalities, Gemini Spark appears in two forms: Gemini Spark White and Gemini Spark Black, representing the Yin and Yang. Gemini Spark also appears at the end of Mega Man Star Force 2, immediately after Patrick reveals the truth about his evil personality.
