All of the s2 episodes have been confirmed and Gagotor was not in it even though he was supposed to be in s2. It was never even confirmed that Gagotor was an episode of his own, only that he is a character (probably a "guest villain" in someone else's episode like Vanisher in Antibug or Magician of Misfortune in Princess Fragrance). It was only assumed that it was also an episode. That assumed misinformation makes this wiki less credible.
To be honest it just really didn't make sense to have a page specifically for it. It hasn't appeared in more than one episode; it's not really a character, object, place or superpower; and the page was kind of empty because they didn't really expand on it during the episode.
Also, I was just about to ask you about an edit on The Heroes' Day. Would the episdoe names under the episode header be a spoiler? I removed the HideSpoiler template, but Mr.inkognito123 re-added it. I just wanted to make sure if I'm right so I can let him know and avoid an edit war.
