Jyo appears sporadically throughout the EtC where he occasionally lends aid to the core characters. Not much is revealed about Jyo early on.
In actuality, Jyo is the creation of Raidencorp's Professor Wellard Rauss, having used Procel's DNA to clone Jet Riot, the only human capable of defeating Zephaniah, his own super-soldier daughter.
Jyo has two appearances. His normal appearance includes blue hair and blue eyes. When he loses control, his hair turns black, his eyes glow red, and his clothes darken. Regardless of this change, Jyo is 5'6" with short hair and wears a set of headphones. His attire includes a blue zipper jacket under a grey overcoat. He also wears black pants, boots, and gloves.
Jyo's weapon of choice is a harpoon with a decorative outcropping on one edge designed like the teeth of a pin tumbler key. At the opposite end is another decoration, this being a key ring with several lever keys attached. There are four holes in the handle at the end which may or may not serve a purpose.

Jyo is a character created to insert the author into his stories. Jyo appears in nearly all of the author's works. It is interesting to note that he slightly resembles Noctis from Final Fantasy XV, however, his physical appearance in EtC had been decided well before the genesis of the Fabula Nova Crystalis project and is actually based on Dark Mousy from DNAngel.
