Lex Loath

Lex Loath is the leader of the Loath family. He loaned a million Zenny to Teisel Bonne and sent Glyde to get it back from Teisel. With Teisel and Bon Bonne as his prisoners, he uses them and other prisoner diggers as his workers to uncover the legendary Reaverbot, the Colossus. The Colossus is probably the largest robot to ever be in any of the Mega Man games. Lex is the main boss in The Misadventures of Tron Bonne. After you beat the game, you'll destroy the Colossus. Also, you'll find this greedy soul in the ocean begging for his life to be spared (probably he can't swim)and then in jail with Glyde.

Trivia

 * His name appears to be based off of the legendary supervillain Lex Luthor of the Superman comics appearing in the DC universe. Both even wear similar clothing.
