Rainbow Mane is a mystical character from the Jetix series Yin Yang Yo! He is the leader of his kind, the twonicorns (unicorns with twin horns).
Role in the series
Rainbow Mane first appears in the episode "The Trouble with Two-ni-corns". Yin and Yang travel to the Valley of the Twonicorns to restore Yin's broken toy, only to be discovered and thrown out by Ultimoose and his goons. But as fate would have it, the rabbit twins land in front of Rainbow Mane and his kin. Rainbow Mane then proceeded to tell the twins about their tale of tragedy. Prior to the events of the episode, his home was taken over by Ultimoose and his rhino security guards. All the twonicorns were held hostage and had their magical horns removed to be melted down into a set of magical antlers for Ultimoose. It was then that Yin and Yang's mission was clear: to restore the Valley to its former glory. Rainbow Mane, the twonicorns, and the twins hid inside a giant wooden twonicorn with fake horns. Once the wooden statue was inside the factory, the occupants leapt out and faced off against Ultimoose and his goons. When Ultimoose tried using the magical antlers he had crafted, their magic didn't turn out as he thought it would, and Rainbow Mane and the rabbit twins used that against him.
Rainbow Mane would later appear in the episode "The Manotaur". The Manotaur held Rainbow Mane and his kin hostage, planning to shave off their hair to make a wig for himself.
