- Keep Circulating the Tapes: The tie-in comic for the attraction, Marvel Super Hero Island Adventures, was only sold at Universal Orlando, and has since gone out-of-print, meaning that online sellers are your best bet if you want to read it.
- What Could Have Been:
- An early concept for the ride had it being a freefall coaster◊; the "Fearfall" name being a remnant of that plan.
- A mid 2010's proposal called for the demolition of the ride along with Storm Force Accelatron, Kingpin's Arcade, and Cafe 4 in order to make way for a massive Avengers attraction. The plan has been shelved for now, as Universal wanted to focus on other upcoming projects in the resort (such as Nintendo).
