After the real Jervis Tetch/Mad Hatter had been sent to Arkham following his debut, a very different Mad Hatter appeared, who claimed to be Jervis Tetch. Unlike the original, was sane and sported a gaudy mustache. He was primarily a thief, apparently obsessed with completing his private collection of hats from all nations, cultures, and historical periods. He often constructed various weaponry concealed inside his hats like flame-throwers and buzzsaws.

The headgear he wanted most was, of course, Batman's cowl. In numerous attempts he tried to de-cowl Batman. After many tries, he was successful, after spraying the cowl with a radioactive substance causing Batman to remove it. No sooner did the Mad Hatter put it in his collection than Batman and Robin arrive. They had traced the cowl with their "super sensitive Geiger counter" in the Batplane.

Later on, "Tetch" claimed to have gone straight, but that turned out to be a lie. It was revealed that he was in fact an imposter when the real Jervis Tetch returned. The real Hatter claimed to have killed his imposter, but the fake Mad Hatter appeared one last time where he ended up being beaten by Batman and has never appeared since.
