Legion of Super Heroes

In the Legion of Super Heroes episode "Legacy", the young Superman meets Lex (voiced by MarkStrong), the "richest guy in the galaxy" in the 31st century, who also has a knack with machinery and access to his own corporation's powerful technology. A redhead who wears a purple jumpsuit (echoing Lex's original hair color and classic costume), Lex starts out as a friend of Superman, but is scorned when he refuses to neglect his duties with the Legion in favor of spending time with him.

To get rid of the "competition" for Superman's time, Lex equips the Scavengers with cutting-edge weaponry and, after luring Superman away with a fake distress call, personally dons a suit of robotic armor and leads an attack on the remaining Legion members. Superman returns in time to aid his friends and makes it clear to Lex in no uncertain terms that he wants him out of his life. Lex resolves to fight Superman, her reasoning being that if he won't be his friend, he won't be anybody else's either. In the fight, Superman tries to tell him that he can't hurt him and he overloads the barrel of Lex's gun and his suit blows up. Superman pulls him free in time to save his life, but in addition to the injuries she sustained from the blast, all of his hair is seared off.

Instead of showing gratitude, Lex is incensed. In the final scene, he has recovered and appears to be regrowing his hair while in prison. His prison uniform displays the name "Luthor" written in the Interlac alphabet. While rebuilding his butler/bodyguard in his cell in Takron-Galtos, Lex ominously states that he is actually grateful to the Legion, since they helped her realize her potential as a supervillainess. Lex is voiced by Mark Strong. He is seen again in the season one finale where the Legion break out the Fatal Five, locked in his cell as he sticks her tongue out at a passing Superman. he's last seen in the second season premiere, his hair still not regrown, escaping with a crowd of inmates.
 * Young Lex makes an appearance in the tie in comic Legion Of Super Heroes In The 31st Century #13. Making his Metropolis debut, Superman saves Lex and the surrounding crowd from Lex's own out of control prototype battle suit. Though this version of Lex doesn't yet show hostility towards the Man Of Steel, Brainiac 5 warns Superman to keep an eye on Lex. Luthor2-1-.jpg
