Dragon Slayer Magic (滅竜魔法 Metsuryū Mahō): As one of the first humans who entered the Dragon Civil War, Kuroko was also among the first Dragon Slayers brought into existence. Over time, however, as he slayed many Dragons, he himself was, eventually, turned into a Dragon due to the extensive overuse of his Lost Magic.
Dragon's Roar - Like all Dragons and Dragon Slayers, Kuroko can perform a Dragon's Roar, incorporating his respective element into a massive breath attack. His blast is a crimson beam which he is able to maintain for extended periods of time.
Shape-Shifting: Kuroko and the Clan Dragonborn, contrary to the legends surrounding them, did not entirely became Dragon and have retained the ability to enter and exit their extremely powerful Dragon Forms at will.
Dragon Supremacy Magic (操竜魔法 Sōryū Mahō): Dragon Supremacy Magic allows the user to dominate the will of a Dragon, effectively making them their subordinate, a remarkable feat, given that most Dragons think of humans as little more than food. However, a Dragon can, with a strong enough conviction, overcome the effects of this Magic, acting, once again, of their own free will. Also, if large amounts of Dragons are present, the user will have difficulty maintaining their control over them.
