2x1 - Mega Man Star Force

A new breed of radio wave viruses have substantiated at a museum, so Geo investigates. While there, he notices a strange aura emitting from a display item called the "Sword of Zerker." Soon after, two new enemies appear (Yeti Blizzard and Dark Phantom) and begin to battle one another for the sword. In the heat of the struggle to protect the sword, Omega-Xis accidentally ingests it, and the enemies flee.
