Snowbird didn't say Northstar should be up there with her and the other ladies, she said she knew there are others who should be up there with them. She didn't mention Northstar or anyone else. The next panel showed Northstar abruptly leaving - that's the gag. Some people take this panel to mean there was something between Herc and Northstar, but that's just an assumption. It's just as reasonable to assume Northstar had a unrequited crush on Herc and nothing ever happened between them especially since there isn't any on-panel showings of any relationship between them.
As for asking Stan and Jack; Stan hasn't written the character in over 40 years and there have been several other creators who would have more history with Hercules and thus have more of a say in what he has/would or hasn't wouldn't do. Jack Kirby died in 1994 so there is no way to know his thoughts on the matter.
well thanks again dude your awesome. by the way how did you get to be such a expert on marvel Hercules anyway ? your info is amazing.
Marvel Hercules has been my favorite superhero for over 30 years and in that time I've attained, read and collected nearly every comic appearance of the character and most Hercules merchandise, too.
