Ojo

Igthar, The All-Seeing, is the main antagonist of the series, and has been the puppeteer of all the events thathave unfolded. He embodies the body of an immortal golden Labrador retriever affectionately named Ojo by an unwitting Johnathan Doe. Contrary to popular belief that his parents have bought "Ojo" for Joe, Igthar had chosen Joe and used his obsession with the paranormal to his advantage to wage war against the mirror world and ultimately claim it for himself.

Powers
Igthar has nigh-infinite world-bending potential, and can alter the very physics of our world, even going so far as to accomplish feats humanity cannot even perceive. As an example, Nikola Tesla may have discovered alternating current, bust was Igthar who bent the world's reality in order to make it possible, as well as give him the idea.

His powers, however, require him to consume copious amounts of kibble.
