Paul. The personification of the Marvel editors responsible for Peter's perpetual msiery. There's a meme that Paul has existed in the comics for decades, bidding his time, planning Peter's downfall, while appearing as a mere bystander in the background of the odd panel.
OMD saga continues. Personally I'm hoping it will end with Uncle Ben descending from Heaven, slapping Peter, kicking Mephisto in the nuts, and taking May away with him.
P.S. Referring to this piece in particular, Peter has a pair of succubi acting as his literal wings, who may be attempting to make his ex jealous.
