Steve Dayton was the world’s fifth richest man and also an adventurer, financier, and professor of psychology. Possessing a huge ego and used to getting what he wanted, he set out to wed Elasti-Girl of the Doom Patrol.

Dayton created a helmet to harness his brain’s telekinetic powers, which allowed him to move objects with his mind. He designed a costume and called himself Mento, hoping to impress Elast-Girl with super-heroics. Surprisingly, his scheme worked and the two were married.

After a lenthy legal battle, the couple adopted the Doom Patrol’s sidekick, Beast Boy. Mento never became a full member of the Doom Patrol but he hung around and helped out from time to time, adding more tension to an already fractious team.
