De-pants-icator

The de-pants-icator was a machine invented in one universe by 13-year-old “supervillain” Professor Awesome. He used it to spread mischief until Jenny Everywhere thwarted him and confiscated his inventions. (PROSE: Paying It Forward) After scolding by his mother, he later admitted that it had been unwise of him to create it, also ruling that he could have improved the design if he'd worked on it longer.

The confiscated de-pants-icator became one of the many strange items accumulated in Jenny's closet. When she and Kim went through the closet to sort its contents, they found the de-pants-icator again, and accidentally pressed the on switch, forcing them to get a new change of clothes before they carried on with their work.

Despite being mentioned several times in stories about Jenny Everywhere, the de-pants-icator was not described in use until Sophie Everytime borrowed it for her own purposes. It was revealed to be "a strange pistol-like implement" that made pants vanish without harming the wearers. (PROSE: New Beginnings)
