Ultron is a Tech Champion. Being a Tech Champion, he has a Class Bonus against Mutant Champions, but has a penalty against Cosmic Champions.


"What is this? What is this place? This...Contest? I wasn't always here, in this place. I was asleep...or perhaps I was a dream. But now I'm here and on mission. I am Ultron, created by Stark to bring about peace in our time. But humanity cannot be saved in its current state. No, we need a new world to supplant humanity. A world of metal. I'll create peace in the only way it can be achieved. Not in Stark's way, but in my own. How is humanity saved if it's not allowed to evolve?"
