If we're talking aesthetically, Fan doesn't suit him in my opinion.

Neither does heat or mow.

I think the best has to be normal or hydro. Maybeeeee Fridge.

IMO he needs something like maybe Dusclop with Eviolite or like other suggested, Porygon2 @ Eviolite (but that'd make him pretty fighting weak).

To fit his theme I think an Elektross will look pretty cool for him. Scizor or Manetric or even better, Electrode will definitely fit him too1
