Imagination

Imagination is the creator of The Multiverse, The Large Void, and The Void. He previously controlled the Multiverse, but gave control to his son, The Founder. He is incredibly powerful, near omnipotent. Nobody knows where he came from, but creating the Multiverse seemed to drain his power, and he is now believed to be deceased.

His two sons, The Founder and The Magician, are both still alive.

His lifespan was ~1 nanosecond, meaning that everything that happened in his lifetime happened within that nanosecond, including creating The Multiverse, The Large Void, The Void, The Founder, and The Magician.
