Nova can be summed up as "What if Peter Parker was the Green Lantern?" The Nova Corps is a space-faring police force - and when a member of the Corps is mortally wounded while orbiting Earth, he has to transfer his powers to a human - high school loser Rich Rider. He can fly, fire energy beams, and he has a sweet costume with a cool-albeit-kinda-goofy helmet. Marvel pretty much tried to set up Nova as the Spider-Man of the '70s - even his rogues gallery kinda matches up. Instead of the Sandman he had Diamondhead, instead of the Vulture he had the Condor, instead of Electro he had Powerhouse, and so forth. His nemesis was the Sphinx, an Ancient Egypt-themed guy whose backstory is so complicated it gives me a headache. Eventually, the book had a long storyline where Rich went to the Nova Corps' home planet, Xandar, and had a bunch of adventures there. The book ended with Rich giving up his powers and returning to Earth, and that was pretty much it for Nova until 1990's New Warriors #1.
Teenage vigilante Night Thrasher wants to put together a team of young superheroes, and Nova is right at the top of his list. He figures Rich probably really still has his superpowers after all, so he asks him politely and runs a bunch of non-intrusive tests to...wait, no, that would be silly. No, Night Thrasher just throws him off a building to see if he can fly.

So that pretty much sums up Nova, although I would be remiss in not mentioning his penchant for freaky interspecies sex. In the '90s, he had a long-term relationship with fellow New Warrior Namorita (who, as the name implies, is Namor's half-Atlantean cousin); during Annihilation, he hooked up with green-skinned alien assassin Gamora (pictured below); and shortly before his untimely demise, he found a temporally displaced counterpart of Namorita (the one from "our" universe having died) and of course started dating her.
