King Of HyperDark from the Deltarune AU: Paper Trail. They're the six dark princes fused together into a big demigod. Their personalities are all mixed up with each other, but they're are main with one that's not fused with them: Asriel. His horns are ripped off of their hat, and their scarf extends longer. All the piece of his clothing are now rainbowy, without the color red, and the symbol in the robe's chest is now the Delta Rune symbol.
