Messier 108

Messier 108 is the largest known living being in the Multiverse, a barred spiral galaxy that has declared itself the Guardian of Good.

Early Life
Messier 108 was born immediately after the Big Bang of Supurb Access-ness created the Pluxa Zone. It quickly grew, and the chemicals that made it up combined in a unique way to create life, but on a much larger scale, eventually leading to the whole galaxy being alive.

Modern Times
Over trillions of years, Messier 108 witnessed life evolving in the Boring Regular-verse, a nearby universe. It knew that eventually, beings from there would come and populate the Pluxa Zone. However, once those beings did come, it witnessed the evils of some groups of those beings, and declared it would try it's best to destroy their evil ways.

Personality and Traits
Messier 108 is very wise, and also very strong (It's a galaxy). It knows how to create portals to the various universes in the Multiverse, and can also reincarnate beings. It can summon the powers of all known Microsoft Program Energies, and is a master at using all of them. It speaks in "a low, booming voice typical of large, powerful beings", and it can control who hears it speak.
