DEC Decay Senior Member Nimrod Vs Ultron the almost inability to be hurt vs the ability to self repair from almost anything. they should be able to detect any weaknesses in the other as well.
SPA Spawnrules Tiger yeah, no, ultron wins the only way to defeat him is to go inside him blow him up
ROU roughrider Thunderer Ultron is insane and virtually inpenetrable. He will have some mad plan to stop Nimrod, the ultimate sentinal.
SMA Smaxxer Senior Member Good thread, but I think Nimrod takes this one. He is just more advanced and is a cold logical thinking bad ass. Ultron is just crazy.
