A new villain, huh? hmm.... A Basilisk or a Kraken.

However, I highly doubt Angels would be susceptible to it's petrifying gaze, or certainly not their true forms. And really, all the Winchesters would have to do is bring Cas and use his Killing Touch, and walla.

Same with the abnormally large squid/octopus--or, Cas could just punch it, extinguishing the life from it.
