The Amazing Prof. Wong

Korean posing as a modern day magician he is actually the first immortal ever created! Has all the immortal’s powers from the Tournament, and even more to boot (including Affect Time powers).

When vampires were first created from the Halloween King the immortals were also created to keep a balance, otherwise vampires would over run the earth. This guy was married and had kids before he became the first immortal. Once he became immortal he could no longer have children and watched over his family as they aged – and he did not.
After a large battle and fight (in the old Tournament's future Ki-Char valley against the vampires) he feared his line was killed off – however, the current family member survived and went into hiding with the only remaining child. That family member died before they could tell the only remaining child what had happened – or where they came from. Hundreds of years later, Sable Blade is the only existing relative to the first immortal. This means that he has the ability inside him to learn all of his powers also – which would allow him to heal his injured back. It would also thereby making his anti-gravity harness, phase blade, and power gauntlets to become obsolete. But first he must learn to fight without them!
The Amazing Prof. Wong would also want to find/train Dr. Shadow-who is also an immortal.
