Megan Williams is a Stage Hazard in All Star Smashers, appearing in Welsford Street. When she appears, she will run around the stage at a really fast pace, damaging anyone she runs into.
- Megan was originally a candidate for the first 2 Empty Slots, coming up short in both of them. Following Empty Slot 2, she was removed from the Empty Slots entirely, as she didn't have enough moveset potential, according to Jack Mayhew. Fortunately, she was brought back as a Stage Hazard on Welsford Street.
