Cool thread!
Supernova was laughing off the combined forces of : the East Coast Avengers, West Coast Avengers, the Fantastic Four, and others. He wasn't even a villain per say, he just wanted to kill Nebula because of the crimes she committed against his people.
On the other hand Lord-Mar-vell was a legit threat to : Surfer, Quasar, Nova, etc...
This could go either way, but my gut says Supernova.
