No, I think it was a one-off joke. I miss Chef, and I think that it sucks he had to die.

Well, Chef is my favorite character, but i don't think he'll come back, especially his Darth Vader alter ego, He died in "Return of Chef" episode, and since then, he was never appeared or even mentioned.

I dont think he's coming back y'know with the nazi zombie boss fight and isaac hayes leaving along with never being named after the return of chef even if we see PC principal and butters mention him

He is very unlikely to be seen again, and it would be rather disrespectful after Isaac Hayes's death.

Who knows he might be a plot point in a new south park movie that may happen (or not)

I think he would but(NO DRAMA IN THE REPLAYS PLZ) but I dont think he's coming back so yesish and noish?(RIP ISSAC)
