Betrayal is one of the most known shadows to Ruby and his friends. He always there, lurking and waiting to correct them on something. He is a self proclaimed protector of dark notebook that has been given to Ruby as an artifact.

He is not the only one though. He always has his shadow pals behind his back. Even though he is smaller than everyone of them, they follow every command that Betrayal says. But, there is some fights that can come in this situation.

He has been kicked out of Shadow dimension due to his constant rule abuse and rude behavior towards four ancient shadow dragons of law. He thinks that it's unfair, but oh well, he lives in the real world now, under the dinner table.

There is a massive conflict between Shadow Ruby and Betrayal. He is the one reason why Shadow Ruby become so agressive and sceptical towards other shadows. Betrayal won't say what he done to deserve this. He laughing and tells you to forget 'bout it.
