About: Palin refers to themselves as they, they want to be seen as one person. They think if they act as one, they'll get along even better. They want to get along desperately, as they're all they have, but sometimes they just can't see eye to eye (Despite their heads being on the same level.) Even as they have an argument every now and then, they get along fine most of the time, and are relatively close Palin has basic telepathy and can read each other's thoughts occasionally, which in their opinion, is quite helpful.
Personality: Palin is two halves of a whole, they feel they were never meant to be together, but they are and that isn't something they can change. So they try their best to agree with each other and respect both of their opinions. Even as they tend to have very opposing views and are very contradictory.
Their dark blue side wants to keep to himself, is very introverted, and is a big pessimist which is why he can barely stand to share the same body with his brother. Although he is very negative, he cares for others so much, but he tries to suppress this with a coldness that he learned from his father.
His other half is very different from him, though. He wants to get to know everybody, is extrovert and is incredibly vain. Though he can get kind of annoying when he's upset, he loves his brother more than the world and is very protective of him. He believes that anyone can be great, and tries to defy the rules placed upon him.
Backstory: Against all odds, Palin was the only chick that survived in the nest, he was born with another head because of a birth defect, caused by pollution in the water and the air. They share all of their organs, aside from their brain, and inherited heterochromia from their father. When their father saw them as chicks, he felt ashamed, and as soon as they had grown their feathers, he left and they never saw him again. The reason is unknown but they feel that it was because of them. Their mother adored her son, took care of them as best she could. Palin was always fighting with each other when they were younger, and they never completely saw eye to eye. But they've resolved their problems with one another as the time went on. They've always known each other as a brother and a friend, not as an attachment dragging each other down.
