The Builder

A force for (relative) good, and has many incarnations throughout the Multiverse, the only explicitly known, albeit least powerful, of which is Jadon Villarreal 1901, an explorer determined to improve the universe through piracy and espionage.
References to the Builder have been observed in many universes, reaching almost legendary status on Earth 66 and on the outer fringes of Earth 2's colonies, and it is a well known term on Earth 1. Whisperings have begun on Earth 801. The Builder himself remains conspicuously absent from these worlds for the moment, and it is uncertain exactly who the Builder is and where he originates from. All that is known is that he is very powerful on each of these worlds.
