"I need no one to take what is mine"
Krayko was a Dramen mutant that appeared in the episode Darkness Bound. Krayko is the leader of a small band of dramen warriors who Dray suspected to be the one who destroyed his village. Since he seeked to rule over old earth he rivaled with the ambitions of Dread Wing. However the two formed a tempary allience that Krayko would help Dread take over Airlandis and the skies, while Dread claimed to let Kraykorule over all of earth, though he got to ambitious and Dread betrayed him in turn by attacking his warriors, he is eventually captured by the Dragonators and returned back down to earth.
Krayko appears to be a very proud and ambitous dramen warrior and appears to have a sense of honour and chivallry when he stopped his dramen form chasing after the dragonators when they returned him home.
