Wow, uhhhhh~ after reviewing all the information I presented on Elio thus far (revised stuff included), realistically speaking, Elio would inevitably become Johan Liebert from Monster with a small mix of both Hao Asakura from Shaman King and Sōsuke Aizen from Bleach - albeit with the absence of arrogance in the face of obtaining a greater power that fits in accordance to his plans; he typically follows the phrase: "If you want something done right, you do it yourself" - sometimes religiously.

As cliché as it sounds, Elio wishes to bond with Arceus and the Unknown collective so he can link himself with all beings across multiple planes of reality; in this sense, he can interfere with the free will of others at his whim while being provided with answers that were once lost to him for one reason or another.
