Mento is a superhero appearing in American comic books published by DC Comics. Mento appeared in his first live adaptation on the first season of the Doom Patrol television series for DC Universe played by Will Kemp and Dave Bielawski. Publication history Mento first appeared in Doom Patrol #91 (November 1964) and was created by Arnold Drake and Bruno Premiani. Fictional character biography Steve Dayton, the world's fifth richest man, builds a helmet to enhance his mental abilities and calls himself Mento. This is an attempt on Dayton's part to impress Elasti-Girl (a.k.a. Rita Farr) of the Doom Patrol. Although his arrogant manner annoys the male field members of the team, he is successful, and in Doom Patrol #104 (June 1966), Mento and Elasti-Girl are married. They soon adopt Beast Boy (aka Garfield Logan). After Elasti-Girl's death, Mento becomes involved in the hunt for her killers, General Zahl and Madame Rouge. In Swamp Thing (vol. 2) #49-50 (June-July 1986), Mento is recruited by John Constantine for a small gathering of powerful beings, in order to assist in a battle taking place in Hell. The demonic forces are facing an entity that could easily overwhelm and destroy them, even with the aid of the divine forces. Using Mento to get a 'read' on the situation, John assists the battle with magical power. Despite the defeat of the entity, Sargon the Sorcerer and Zatara both burn to death and Mento is driven insane (this was before the Swamp Thing and John Constantine switched into the Vertigo continuity and the event has subsequently been referred to in several mainstream DC Universe comic books). Shortly thereafter, Dayton, now in a wheelchair, resumes his Mento identity and lashes out at Garfield Logan, blaming him for the deaths of the original Doom Patrol. He then proceeds to create his own team, the Hybrid, to challenge the Teen Titans. After multiple encounters, the members of the Hybrid defy Dayton and join the Titans in curing him. Raven cures him of his madness and he seems to discard the helmet. Much later, Dayton hires Deathstroke the Terminator to find the Titans during the Titan Hunt. Afterwards, he becomes the and tries to frame Deathstroke for murder, but Dayton's dual identity and plans are revealed and Deathstroke is cleared of all charges. The 's plans also involved nuclear bombs placed across the country, but this is neutralized by a
