Xilatealeon (Neo Ultimorian Canon)

(I can personally never understand why likes this guy so much. Even to this day, I'm baffled by how one of my oldest creature designs, and this one in particular, is so well received by everybody I have shown Xilatealeon to over the years of it's existence. In VD's case, he says Xilatealeon, out of a lot of my designs, is perhaps the most biologically possible since it's basically the same type of body build we've seen before in prehistoric amphibians and reptiles; quadrupedal, amphibious in nature, large body size, etc.. Still, I don't get how he says that when Xilatealeon's most famous attribute is it's Hyper Beam-like attack that in all it's incarnations it's always had access to. That's not even getting to the Aurora creating tail boomerang energy attack it has from the tail.)

Name: X
Species: Xilatealeon (Zeal-a-teal-ion)
Motif: Irradiated Megalania
Target: Dr. Devoniak

X, or simply called "Xilatealeon" after his own species, is also given the nickname of "Specimen-010", and is a Legendary Creature that has existed in Ultimorian History for a long time. From the now deceased Albino Deity Class Xilatealeon known as Oblivion, to the now longest lived specimen that X currently is, and is also notable in differing from the reborn species a tiny bit in the Neo Canon. Due to his origins as an Irradiated Megalania that fell into a dimensional void during a massive earthquake, and became exposed to so many mutations so rapidly that the creature was warped into the first ever Xilatealeon, X is notable in differences between him and the other Xilatealeons that exist. X is capable of firing a massive beam of pure energy of an unidentified type, whereas the modern subspecies breath either a hot or cold beam of energy that is far less destructive in nature. Not only that, but X's tail fin is enlarged to the point X is much, MUCH more adapted to the aquatic life than his two descendant species are known to be.
