Neo (The Matrix) vs Lord Ultron

*** Prime Directives ***

Lord Ultron (annihilation conquest) - to conquer all life and remake in his own image

Battle Happens on Earth.
Lord Ultron has conquered the Phalanx
Neo has continued to evade Ultron so the fight will have to happen online.

Neo has 24 hours prep to keep Ultron from assimilating the Matrix.

I..am quite confused as to how you think Neo stands a chance when he couldn't even beat Smith. Unless you're relying on these vague abilities like when he jumps "inside" Smith, but there isn't any reason to think this would work on something as advanced and powerful as Ultron.
