Reflux (real name Gus Burns) is a character in the 2018 sequel Incredibles 2. He is a senior who has the unsettling super power of heaving hot lava, which helps him break into some of the most secure locales. Reflux is part of a group of second-rate Supers who aspire to join the ranks of superheroes.
- Although this character heaves hot lava, his name was originally GERD because that is the technical term for acid reflux. His name was later changed to Reflux since GERD was a little too "on the nose".
