Bullet Proof Vest: Wore one of the Panther's vibranium laced suits under his police uniform instead of the standard issue Kevlar vest for a while. He later began impersonating the Black Panther using it, and still has one as White Tiger.
Moral Myopia: He hates T'Challa for destroying his hand and keeping him from Wakanda's Vibranium, while ignoring the fact that he tried to enslave the Wakandans and casually killed T'Challa's father in front of him.
Dirty Coward: Despite his considerable physical advantages over T'Challa, he repeatedly resorts to poison and sneak attacks and has never used Wakanda's tribal challenge to try and legitimately oust his rival.
Majored in Western Hypocrisy: During Priest's run, he casually dismisses Queen Divine Justice's objections to the White Gorilla religion's practice of female genital mutilation as a view conditional on her "Western ways."
Religion of Evil: Heads the White Gorilla Cult, which aims to return Wakanda to a state of primitive traditionalism that includes human sacrifice.
Always Someone Better: He's T'Challa's intellectual equal and his physical superior, serving as one of the few people who can regularly best The Black Panther in hand-to-hand combat.
Alien Phlebotinum: He and his minions derive their physical powers from the mutating energies of the Resurrection Altar, which is actually some sort of alien device that landed in Wakanda millennia ago. It can also bring back the dead in limited ways.
Evil Genius: You have to be to get the drop on T'Challa.
Faux Affably Evil: He's superficially quite courteous to people who seemingly aren't in the way of his vendetta against T'Challa, but as Ross points out, he's actually trying to manipulate people this way and knows full well that he's incredibly intimidating even when he's being polite.
Hoist by His Own Petard: When he finally deposes T'Challa in ritual personal combat and subsequently goes through the Panther ritual, his mutated physique — which allowed him to outmatch T'Challa — reacts very badly to the Panther's sacred herb and puts him in a Convenient Coma.
Happily Adopted: Toyed with. White Wolf clearly cared for his adoptive father, T'Chaka, and is head over heels in love with his adopted culture. However, he was never able to overcome the institutionalised xenophobia that characterises Wakanda, was relegated to a behind-the-scenes job by T'Chaka, and is jealous and resentful of his full brother, T'Challa, who does not have to deal with any of these problems.
Hired Guns: Became a merc after getting run out of Wakanda.
