Pluto

From Megaman Mush Wiki

Pluto is the furthest planet from the Sol sun, in the solar system Earth is a part of. It was connected to the Stardroid Pluto, who was based around the concept of ice and death. It is also the current resting place of Ra Moon, whose waveform signature is currently trapped inside a very large fused piece of 'Minus Metal', the remains of the Pendants.

Attempts by a Ra Moon cult to use a Stellar Drive to open a portal through space to the planet Pluto were foiled by the efforts, chiefly, of Blues and Daryn, despite interference from Energize. The portal to Pluto did not open, and instead caused San Angeles to disappear and be replaced by the alternate Neo Arcadia. This was the beginning of the third Alternate Universe TP.
