"Worried."

There's a couple points in Marvel continuity where alien races realize, earth had driven off Galactus, more than once; and was thus probably insanely dangerous. If they had the planet under any sort of surveilance, they would probably have seen X-Men #59, wherein Cyclops pulls the Star Trek logic trap on the Sentinels, convincing them the sun was the source of mutations, so they should fight it? Enh, to a lot of A.I. that probably makes sense. That, Ultron, and I think a lot of robot bad guys are beat by getting launched into space; so from the outside it probably looks like earth is littering the universe with those things. 

We got the Super-Adaptoid pretty cheap from a Disney sale, but I still feel like he needs a little extra something--definitely a cape, possibly with a big flared collar; or at least Yellowjacket style 'wings.' I kind of love the Super-Adaptoid, and hate Nimrod, even for a bad robot he's a bad robot. He's overtly racist, and no-sales too many attacks, or rebuilds/recovers way too fast. Cheap! That and I feel like S-A could conceivably improve itself, maybe in an evil way like in Avengers #290, but still trying; while Nimrod might pay lip service to that and not really care: it just wants to kill mutants. I really think Claremont was maybe building up to that and got sidetracked: Nimrod is a friend to all children!...until you develop mutant powers, then ggggak!
