Wrathion

Wrathion, the Black Prince, is one of the few black dragons on Azeroth known to be uncorrupted by the taint of the Old Gods and, following the death of Deathwing and the destruction of the corrupted black dragonflight, one of the last known black dragons alive on Azeroth. Claiming to have seen a future where Azeroth falls, Wrathion helped heroes of the Horde and Alliance gaining powers, usually in the form of magical legendary items. He is, however, ruthless in his goals and pursues what he perceives as the greater good for Azeroth with almost fanatical devotion. As the self-proclaimed last black dragon, Wrathion believes that the titans' mandate to protect Azeroth now falls to him, and he will do whatever it takes to fulfill this charge once entrusted to Deathwing, that he personally identifies as his father. Most dragons do regard their Aspect as their progenitor since they were the genesis of their kind out of the proto-drake stage of evolution, albeit through the direct hand of the titan watchers, but with Deathwing's infamous history it carries a bit more significance. After being purified and hatched during the war against Deathwing, Wrathion saw to the death of every other black dragon he knew of, including his father. He decided to take on the appearance of a dark-skinned human for his mortal disguise, and provided an adventurer rogue with the Fangs of the Father to hunt down the last dragons of the black dragonflight in Azeroth. After he nearly survived an assassination attempt by the red dragonflight, he claimed to take his destiny into his own hands and disappeared. He later would claim to be the self-proclaimed leader of his flight. As the Alliance-Horde war intensified on Pandaria, Wrathion traveled to the once hidden continent and created his own organization, he then sought to use an adventurer gifted with a powerful cloak of his own creation in a plot to have one side wipe out the other, making the world more secure against greater threats. While his plan ultimately failed when King Varian Wrynn decided to make peace with Warchief Vol'jin instead of dismantling the Horde, Wrathion's ambition to safeguard the world remained unchanged. After he helped Kairozdormu release Garrosh Hellscream during his trial, Wrathion stayed in the shadows, observing the conflict between the forces of Azeroth and the Iron Horde, and which side would win the war in Draenor. With the Dragon Isles rediscovered, Wrathion now contended with Sabellian for the right to become the new Aspect of the black dragonflight. This competition ended when the two brothers delved into Aberrus, the Shadowed Crucible. Realizing that he did not need to be Aspect to aid his flight, and that his reasons for pursuing the position were skewed, Wrathion withdrew his claim for Aspect. Instead, he and Sabellian both realized they were not suited, instead turning to their brother Ebyssian, who had been counseling them the entire time, to become the new Aspect. After Ebyssian was acknowledged as the new Earth-Warder by Alexstrasza, Wrathion was made the diplomat of the black dragonflight to lead alongside him and Sabellian.
