Accelerus Maximus is one of the Demonizer Eight Generals in Superhero Keyblade Wars. He is a literally motor-mouthed speed demon who leaves pollution and disease in his wake. Accelerus is impatient, efficiency-obsessed, and has very little, if any tolerance for any setbacks for his empire's campaign. He can transform his limbs into wheeled appendages in order to chase down targets and get around quicker.
- "You're either very stubborn or very foolish!"
- "So you've made it this far? But you'll go no further!"
- "No one escapes me! No ONE!!"
- "I'll chase you to the barren ends of this mudball, if I have to!"
- Accelerus is based on the Decepticon Combiner Menasor from "Transformers".
- Accelerus also draws inspiration from the Mad Max film series, particularly one of the villains who was previous portrayed by Vernon Wells.
- His transformed semi-vehicular state slightly resembles the Tumbler from The Dark Knight Trilogy.
- A deepened, lower pitched version of Darth Vader's breathing sound is heard when Accelerus emits gases from his mouth.
