Nine Tails is an iteration of Tails that was spawned in the alternate Shatterverse called New Yolk City. Nine had a harsh life, and became bitter because of it. He hated the world he was born in, so he turned his back on it, claiming the world turned its back first. With his seven mechanical tails, he can climb walls and manipulate other objects if he is tinkering. When he first met Sonic, they were enemies, but feels as though Sonic can’t be fully trusted. He was “betrayed” by Sonic twice.
