Trivia / The Supervillainy Saga

• Hypothetical Casting: The author set up a fan casting page.
• What Could Have Been: According to Word of God, the 5th book of the series was supposed to be called The Kingdom of Supervillainy and would be one extended homage to The Castle of Cagliostro as well as Gary vs. Doctor Doom. The story ended up being abandoned halfway through and was replaced with The Tournament of Supervillainy that was a Mortal Kombat homage instead.
• Word of God: The history of the universe is detailed on the author's blog The United Federation of Charles.
