6. Sportsmaster

Gotta throw in one Golden Age Green Lantern villain, and I picked Sportsmaster to fill that slot.

Lawrence Crock earned the nickname Crusher on the football field, as a brutal player who would do anything to win. Despite making his name at football, Crock was actually a talented athlete in multiple disciplines, and when he was booted from football for breaking multiple rules, he put them to use. No, not by playing another sport, but by becoming a supervillain. Duh.

Crock got himself a costume and mask and took on the identity of"¦the Sportsmaster!!! In this identity, he clashed multiple times with Alan Scott, aka the Green Lantern, always faking his death to escape when beaten, which is a pretty hardcore way to do it. He eventually joined the Injustice Society, and met the Huntress (the Golden Age one). He married her, and they had a kid. Then he died. For real this time.

Fortunately for Sportsmaster fans, he resurfaced in another way later. The villainous Council, notable for being the enemies of the criminally underrated Manhunter, decided to use their perfected cloning technique to clone"¦The Sportsmaster. Not Superman, not Bane, but Sportsmaster. This is a smart plan, and I see nothing wrong with it.
