9. Space Ghost/Green Lantern

Space Ghost: Space Ghost was a space-based crime fighter who worked with three side kicks, Jan and Jace the humans and Blip the monkey. He flew around space fighting evil villains, including Zorak the Mantis, Moltar the Molten Man, and Brak the Cat Alien. Decades later, Space Ghost would be revived sans sidekicks for a Cartoon Network show and proto-Adult Swim humor originator Space Ghost Coast to Coast. Which is the best show ever, and one you need to watch. Watch it now. Seriously. Go away. Watch it. Zorak was the best fictional character of all time. He was the lone locust of the apocalypse, and you’ll think of him as you look to the night sky.

Green Lantern: Hal Jordan was a test pilot with Ferris Aircraft who had reputation for fearlessness. One day, when Space Sector 2814's Green Lantern Abin Sur crash landed, leaving him near death, his ring sought out the most courageous person on the planet. And that turned out to be Hal Jordan. Hal was given the ring and made a part of the universe's team of space cops, the Green Lanterns. Hal fought for numerous years, escaping both possession and death and helping to found the Justice League of America.
