☄ Generally appears to be a mortal man, hale though of late years. But he is under a spell – certainly a curse, in his mind – of immortality that links him to a female gargoyle named Demona. Having sacrificed his youth as part of this supernatural pact (at the spell's onset he was in his thirties), he still shares the gargoyle's vitality. He can disguise this fact when it suits him, even exaggerating his apparent age to the point where he seems a bookishly innocuous older man. But when he drops all pretense, his strength is obvious; the silver-white hair is the only truly infirm thing about him.

☄ Macbeth is certainly stronger and faster than the average person, since in canon he holds his own in toe-to-toe combat against multiple gargoyles. But he's not defined as possessing superhuman powers, other than the fact that he cannot be killed by any disease, force or being besides Demona. His status as an exceptionally dangerous opponent probably has more to do with his having had long centuries to develop his physical prowess, hone his fighting skills and acquire tech-enhanced weaponry. And he has spent all those centuries hunting the creature with whom he shares a magical bond.

☄ He was the historical King of Scotland for a time, but his involvement with gargoyles and the subsequent curse left him no choice but to fake his death in the year 1057. Since then he has traveled extensively, committed himself to various scholarly studies, and amassed a great deal of wealth – all the while pursuing the destruction of Demona, and by necessity his own true demise.
