The Animated Adaptation of the Legion of Super-Heroes comic book series. Ran for two seasons, 2006-2008, abruptly ending with a hook for the third season that never came.When the series opens, the 31st-century Legion is hopelessly outclassed by the famed Fatal Five. They resolve to recruit the near-mythical Superman from the past, but for undisclosed reasons, Brainiac 5 brings them to Smallville, not Metropolis. There they invite 18-year-old Clark Kent to help them in The Future, promising that with Time Travel, he can return the minute he left.At Brainy's insistence, everyone studiously avoids telling Clark who he's supposed to become in the future. Regardless, Clark finds the Superman Museum, connects the dots, and takes the costume from the display case, and the name of Superman, for his own. Together they defeat the Five, and then Adventures Happen.The show had a very Silver Age tone to it, but the most noticeable and controversial change from the source material was turning team genius Brainiac 5 from a Human Alien into an android. Word of God is that this was supposed to tie him more closely to his ancestor the original Brainiac, as well as avoiding having to explain how an an organic can be the 'descendant' of a robot, clearing away a fifty-year-old example of Writing Around Trademarks.Season Two saw everyone age about two years, even Brainy, and the show went Darker and Edgier after the very light and bouncy first season. The premiere visited a Bad Future where Superman's clone was bred to fight Galactic Conqueror Imperiex, who when cornered escapes back to the 31st century and proceeds to wreak havoc as the season's Big Bad.The series had its own comic series, Legion of Super-Heroes in the 31st Century, which ran for 20 issues, some of them taking place after the end of the show.The character sheet can be found here.
