Trivia

 * The Negative 10 are similar to the Spider-Man villain team the Sinister Six. Just like the Sinister Six being a group of Spider-Man villains desiring revenge against the wall-crawler, the Negative 10 is a villain team composed of villains Ben Tennyson has fought that has been brought together so all of them could have a chance to defeat him.
