who come close to apprehending the Six until Mad Hatter steps in and uses his mind control abilities to subdue the Doom Patrol singlehandedly, going so far as to almost make Elasti-Girl eat Beast Boy before Scandal stops him. In a later issue of Secret Six, Tetch reveals that he has designed a hat to make him happy beyond the measures of what illegal drugs can. He also states that he has planted miniature listening devices around the House of Secrets to keep tabs on his fellow members. After revealing the true motives of Scandal Savage to leave the team, the Secret Six go after her, finding themselves at Vandal Savage's temple in the mountains, where Doctor Psycho starts attacking the team. Tetch easily gets the upper hand on Doctor Psycho until Cheshire appears and stabs him in the back with a poisoned dagger. Scandal tends to Hatter's wound, and Catman administers an antidote to Tetch. While the Six face off against Cheshire and Vandal Savage, Hatter takes on Doctor Psycho one on one, and emerges victorious despite his injuries, gravely injuring Dr. Psycho with Cheshire's dagger. At the end of the miniseries, Hatter saves Scandal from falling to her death, and the Six befriend him. As Hatter stands atop Savage's destroyed base with Rag Doll, he promises to be a very good friend in return. Rag Doll then pushes Hatter off the roof, seemingly to his death, saying there was "only room for one dandy freak on the team". However, it is revealed on the final page that Tetch survived the fall. Heartbroken, he vows revenge on the rest of the Six. Prior to the events of Gotham Underground, Tetch falls victim to his own mind control devices at the hands of Tweedledum and Tweedledee.

Once the three are returned to Arkham, the Hatter quickly exacts revenge on the two, manipulating them into a bloody brawl with his mind control chips.
