Dream

Dream is an AI inhabiting a robotic lykoi cat, who serves his friend Myth. He used to be a wish granting computer, but was tired of the box he was trapped in. Myth had found Dream, and simply wished for a friend, and the had to follow the protocol, while getting what he wanted. Turns out, Myth was no ordinary cat, but a strange interdimensional alien, and somehow, they could transfer the AI into Myth's "heart". He was then placed into a robotic body, and travels around with Myth, helping them out with their adventures.

Dream wants more than just a robotic cat body, and kinda wants to take over a world. or two. or a universe. But... It DOES interfere with the "friend" wish Myth has, and since he must be their friend... He can't.

Doesn't mean he can't be sneaky about things though...
