Jeffy Og
Jeffy Og (not to be confused with Jeffy) was believed to have been a god-like being that led the Childpornogians in their invasion of the Universe 900 billion years ago that almost destroyed the entirety of the Allahverse.
Jeffy Og is described as a corrupted version of Jeffy from one of the infinite realities of Old Nome. It's believed that due to his name, the Docy O Og of his reality was also corrupted which led Jeffy Og to become evil. It's theorized that Jeffy Og had taken over the Oggahverse in his reality and somehow transported himself and the creatures to the Allahverse in order to conquer it. His motives for this invasion and wanting to conquer it was that he wanted to prevent the existence of Green Beans and the SML series, because he didn't like being represented as a retard with a pencil up his nose, which in his reality is considered a sign of mockery, though he didn't realize that in our reality having CTE is a sign of ultimate vril.
It's unknown if Jeffy Og and Jeffy himself had any contact during his invasion, although it's believed that neither of them allowed themselves to see each other as they believed it would destroy the fabric of the Gabyverse if they came into physical contact.
Jeffy Og was killed by the Allahverse Pantheon at the end of the 500 Year Childpornogian Invasion Of The Universe and Panhandles were directly created as a result of the amount of carnage he caused.
