#3 Rob Zombie (WWE RAW, June 28, 2010)
Heavy metal musician and acclaimed filmmaker Rob Zombie seems like he clashes with WWE's programming these days. But he shockingly made an appearance on WWE RAW on June 29, 2010 as the guest host of the show.
He delivered a promo in the ring, and he also he announced the participants in the upcoming Money in the Bank match. It was evident that Zombie didn't bring out the unhinged side he's usually known for. Instead, he played it safe and did what WWE asked him to do.

Edge then appeared on the screen, and he said was dumping Zombie's song, "Never Gonna Stop." The former WWE Champion had previously used the song as his theme music. Zombie fired back by saying that he was dumping Edge, as he couldn't stand "The Ultimate Opportunist."
This was the only appearance Zombie made in WWE, though he's still friends with Edge in real life. In 2021, the only Superstar who seems to line up with Zombie's tone is The Fiend, or Bray Wyatt.
