To the end of that scheme, Jervis sent three of his henchmen to Batman's location in order to invite him to his tea party, by singing a message to the tune of 'London Bridge is Falling Down', and then electrocuted them when they finished delivering the message, which knocked them out. 'Welcome to Wonderland, Batman!' -Mad Hatter

However, Tetch felt that the vigilante known as Batman, who had emerged in Gotham in the last two years, could provide an additional edge to his gang, and so, he hatched a plan to capture the Dark Knight and use him as his latest pawn. By that stage, Tetch had improved his mind control technology to the point where he could use it to render weaker minds completely malleable to his suggestions, which enabled him to use the technology on several criminals and formed a small gang to assist with his schemes. Tetch soon found another girl whom he believed to be Alice, and kidnapped her, with the intent of using the mind control technology to return her to Wonderland. Tetch had already committed several crimes before the Christmas Eve Incident, including the murder of a girl named Stephanie Williams, however, the GCPD did not make an arrest, due to the Hatter being smart enough to cover his tracks. Tetch began to kidnap young women whom he suspected of being Alice, and murdered them when he found out that was not the case. Tetch began to believe that she was somewhere in the real world, and that he had to find the real Alice. Tetch obtained a hat shop in the Bowery district of Old Gotham, and continued to develop his mind control technology while he worked there, and became fixated on the concept of Alice, the protagonist of the story. Unfortunately, Tetch began to believe that he was the real-life incarnation of the Mad Hatter from the story, Alice's Adventures in Wonderland by Lewis Carroll.

Jervis Tetch was originally a scientist who proposed that there was no such thing as free will, and that the mind could be controlled by the use of chemicals.
