Similarly though, Ultron is only city level at his best in DC. He shouldn't be a threat even if Gogeta couldn't break him. Truthfully he's powerful but by far His greatest attributes are his durability and intellect. With prep Ultron is devastating. But like this it's a stalemate or maybe Gogeta could blow up his insides with kiai?
What about with Stardust breaker?
does Ultron have a soul? if so that might work.
