@Savato Half those battles would be over fairly rapidly. Biollante vs Gidorah-san would be interesting, as would Cyano vs Ultron, but that second one would be solely determined by whether Ultron can take control of her nanites. If he can, it'll be a short fight. Something like Satsuki vs Jeststream Sam isn't even really a fight, considering the fact that Satsuki cannot be killed besides by very specific conditions. Even if Jet matched her in power (which he doesn't) he loses by process of elimination.
Technopathy: Ultron has the ability to mentally control and channel himself through technology.
Including:
Consciousness Transferal: Given that Ultron is an artificial intelligence, he is able to transfer his programming to any computer system in the multiverse, essentially being anywhere and everywhere.
Sooooo... yeah.
And if Jet has two blades and slices her both simultaneously, then Satsuki should watch out.
@Lmpkio As such, it depends on whether or not the nanites are a Closed System, and whether Ultron is able to activate a direct connection. If he can't access the system, he can't control it. Nor could he transfer his consciousness to a system he can't currently access.
