How powerful would Ultron be if...

[FrostMouse0]

he merged with other powerful AIs/Robots/Sentient Computer Viruses

-DarkDeath Evilman

-Brainiac

-Dragon Ball Androids

-Megaman Robot Masters, MMX Mavericks, and/or Sigma

-Tengen Toppa Gurren Lagann

so on and so forth

Edit1: For more fun, who then in the Marvel Universe (short of omnipotents/near omnipotents) could beat him or if it would take large groups of heroes, villains, etc to do so?

 

[The_King_of_Prudence]

At least 1-C, likely far higher.

 

[WHYNAUT]

He'd be the most powerful robot on this site. Unless I'm forgetting some other godly robot.

 

[The_real_cal_howard]

The Thought Robot

 

[WHYNAUT]

Oh yeah, that's a robo too. Totally forgot about him.

 

[The_real_cal_howard]

Also...Demonbane. Multiple versions of Demonbane...

 

[WHYNAUT]

I don't know much about Demonbane so yeah.

DB Androids aren't that impressive besides maybe 21, and not sure if they can be assimilated since they are part organic.

I guess Demonbane is the most notable of the machines, other powerful machines are Amazo and this goofy robot (I even made a match between these two).

 

[WHYNAUT]

Goofy indeed..
