Mechanic (24 Hour Comic 2019)
From Jenny Everywhere Wiki
A young, androgynous-looking mechanic worked at the garage of the interdimensional city of Shelterville alongside Stan and Jack. They knew how to operate the interociter, which it once fell to them to use to call Jenny Anywhere's car for help at Greta Överallt and Tammy Shotwell's, with Jack and Stan having been otherwise occupied at the time. Later the same day, the young mechanic attended the swearing-in ceremony of Shelterville's new Justice of the Peace, standing next to Jack and Stan. (COMIC: 24 Hour Comic 2019)
