The Dragon is a minor antagonist of the OK K.O.! Let's Be Heroes! episode We Are Heroes where it is seen attacking Ted Viking and Foxy's home (due to it being malnourished), luckily K.O., Rad, and Enid use Rad's van to fly over to fight the dragon, as Rad launches K.O. into the air to punch it, then Rad flies down and catches a falling K.O. and Ted Viking thanks the trio for stopping the dragon. Then it later returns attacking Ted Viking and Foxy's hut again (this time while chasing K.O.) the dragon wasn't really an evil dragon, it was just hungry for glorbs, when K.O. fed them to the dragon turning it partially malnourished, then they realize the glorbs were underneath Ted Viking's hut, as Rad moves it out of the way, and the glorbs start to float from out of a crack, the dragon flies over and eats the glorbs and returns back to normal and flies home happily.
Appearance[]
When the Dragon is malnourished it is yellow and white, if partially malnourished it has a red stripe and is friendly, and when normal it is rainbow colored.
Powers and Abilities[]
the Dragon can only eat Glorbs to survive, having their scales turn into seven colors like the rainbow. However, if not fed with Glorbs, the Rainbow Dragon loses its seven hues, leading it to go berserk and harm on those around it such as attacking Ted Viking and Foxy and their home residence.
