The Merger Magikoopa

The Merger Magikoopa is a young Highest that aims for creating a perfect world where everything is the way his favorite characters (Sonic, Bowser Jr. and Sans) want.

History
The Merger Magikoopa wasn't allowed by Alfather, the leader of the Highests, to create his own timeline until the demons, led by Zaglo, were defeated. A while after he achieved his full power, he had no zone. However, he found Exetior, one of the strongest demons, who tried to stop Alfather from erasing Sally Acorn from existence, but he demonized the wrong timeline. Although the Merger Magikoopa tried to erase Exetior, the latter revealed he was a Highest at origins, but joined Zaglo after learning that Alfather was plotting to erase the whole Multiverse after Zaglo's defeat. Despite the fact that the Merger Magikoopa didn't originally wanted to believe Exetior, he learned that Exetior was planning to betray Zaglo when things were looking bad for the Highests, and that the only deities he was going to spare were the ones he liked, such as his apprentice, Negagen the Wave Demon. After learning everything about the motives of all sides in the war of the deities, he started to plan creating his own zone against Alfather's will, in a way subtle enough so Alfather wouldn't figure out until it was too late and he, the Merger Magikoopa, succeeded. Noticing the second Genesis Wave, the Merger Magikoopa thought that Eggman and Wily would try to go even further with their timeline manipulation, and thought about hijacking their plot. Originally, he thought that Bowser would help, but before he realized that Mario would interfere, it was too late, as Bowser already started his plan. He then drove his attention towards Sans Gaster. The Merger Magikoopa made a deal with Sans: if Sans would help the Merger Magikoopa with his plan, the latter would give the former all of his family back. As part of his part of the deal, the Merger Magikoopa turned Sans's mother into his guardian angel. After the Super Genesis Wave, the Merger Magikoopa and Exetior made a truce: as long as the Merger Magikoopa would only erase demons Exetior hates, the latter wouldn't demonize the former's "Neo Prime Zone". Ever since, the Merger Magikoopa was hunting for Sark, a rapist demon, along another friend of Exetior, Kostas the Hedgehog, an alternate version of Sonic, although Kostas is unaware of it.
