- It turns out Ray was lucky! In "Indestructible Henry", it's shown that when other people were put through the desensitizer machine, they not only became indestructible, they also grew extra body parts! One guy had a face on his belly, and another guy had arms pop out of his ears that constantly poked him in the eyes!
- Schwoz theorizes that because Ray was a young boy, he did not suffer any mutations. He decides to test it out on Henry, who is also a young boy. Unfortunately, Schwoz was wrong. Henry does get a mutation: he breaths fire every time he laughs! As Henry stated, he could burn anyone's face off should he laugh!

- In "Part 1: A New Evil", the new villain, Rick Twittler plans to drain Captain Man and Kid Danger of their powers and use those same powers to create a biological computer virus that will shut off the internet permanently. While people can live without phones and computers (despite the fact that the people of Swellview go crazy if they can't send a single text message), what will happen to vital machinery that runs on the internet?
- And to make things worse in "Part 2: A New Darkness", Rick Twittler succeeds, and all the power in Swellview goes out!
- And in "Part 3 : A New Hero", Rick Twittler gets infected by his own computer virus (thanks to Captain Man punching him into it), turning him into a viral version of the Borg, intent on spreading itself to humans! Thankfully, the virus only infects only one henchman and the process is reversible.
