Big Brother Instinct: Towards Xion and Sora
Badass: In canon and after almost two years with less than seven deaths definitely in the tower too
Badass Longcoat: He still wears the Black Coat the majority of times when he's expecting a fight
Black Knight: Has shades of this
Blind Weaponmaster: Formerly, since he has shed the blindfold. Though he can still fight without seeing, if the need arises.
Casting A Shadow: Though he's been learning more elemental magic from Terra, Darkness is still his primary affinity and he is most comfortable falling back on this element
Flash Step: Some of his Dark moves have shades of this
Incorruptible Pure Pureness: After having once been down the road of The Corrupted (and learned from it), and mastering his own Darkness, he has at least shades of this
Dark Is Not Evil: kind of a personification of this
Jerk With A Heart Of Gold: Can be kind of Stand-Off-ish with new people and tries to keep others on distance, but is utterly loyal and protective once won over
Not Good With People: Mix of both types really. He may or may not have unlearned his people skills during his time working for DiZ. The tower hasn't been much help in regaining them
The Nose Knows: Being able to sense the Darkness/Light of a person's Heart is still his most useful ability
Take The Third Option: Done so in canon, and will continue the Road of Dawn
Thinking Up Portals: Darkness Corridors are his second most useful ability
