Eve the Joltik - Jules's top student when Eve was learning in Steel City. Eve's very knowledgeable about machines and their inner workings and is able to replace and fix parts of technology that's been the pride of Steel City for centuries. (Jules knows the most about that, but Eve took to it quickly).
Due to a series of events, Eve ended up going to Alomomola City alongside Wind to look after a piece of machinery...
Wind the Sandshrew - A former construction worker, Wind learned from Eve on the side, as he was not allowed to take part in official lessons on the specialized machinery of Steel City. Eve taught him what she knew, anyway, at great personal risk. He helps her maintain a very peculiar piece of machinery in Alomomola City.
Vendetta the Porygon-Z - Nicknamed such by Wind after refusing to cooperate to smoothly run the casino among other things, Vendetta has caused quite a few "hiccups" in the system from time to time.
