Josh is a huge Doctor Zone fan, to the point he spends most of his time in costume. A fellow fan accused him of being an 'elitist' after Josh claimed that anyone who couldn't speak the Trashcandroid's Binary language didn't deserve to be in the lineup for the premiere of the movie. He doubted Sara when she claimed that an episode of Dr. Zone was shot on the ranch they were investigating.
Josh has olive toned skin and short, curly black hair. His face is covered in stubble. When dressed casually, he wore a white T-shirt, brown pants with visible seams, and grey-brown shoes with white soles. Most of the time, however, Josh dresses in a Doctor Zone costume.
In "The Wilder West", he was skeptical when Sara said that the Nowhere Desert Dude Ranch was the shooting location of episode 576 of Doctor Zone. After misinterpreting a comment, he and the others who came to investigate concluded erroneously that it was not.
In "Missing Milo", Josh is working as a cashier at a local grocery store. Zack asked him if he'd seen Milo, to which he cheerfully responds that he hasn't.

“Are you sure? I mean this could be any wall.” “Josh, why can't you accept it? This is the actual wall!” —Josh and Sara[source]
“And through some of you may have doubted me... Josh. My instincts never let me down. I knew this was the very dirt where they shot Doctor Zone!” —Sara Murphy[src]
