As already known, Rex, a Dracomon and digimon partner to Jake, can digivolve into Slayerdramon.....But, if he were to Bio-merge(fuse)with his trainer instead, he would obtain a vastly more powerful Mega level.....

THIS is DracoPaladinmon, an incredibly powerful Royal Knight Digimon, In this form, Jake and Rex think and fight as a single entity, their teamwork and friendship given physical form. And it outclasses Slayerdramon in power.

Robin-The-Tactician (Lets just say that Jake and Rex unlock this when they face off against both Ganondorf AND Bowser)
