If there IS alien super-inteligence in our own galaxy, then what it could be like?

For a moment lets assume there is some alien intelligent life on our galaxy which is older than us and that it have succeeded in creating super-intelligent self-modifying AI.

Then what set of values and/​or goals it is plausible for it to have, given our current observations (I.e. that there is no evidence of it`s existence)?

Some examples:

It values non-interference with nature (some kind of hippie AI)

It values camouflage/​stealth for it own defense/​security purposes.

It just cares about exterminating their creators and nothing else.

Other thoughts?
