During the same episode, the club adviser, Coach Beiste was shown wearing a costume while talking to Finn. She was dressed as the Beiste Master.
Blaine is seen dressed as his alter ego during the Senior Lock-In, saying that that ocassion might be the last time he gets to be Night Bird, before he grows up and joins a "fetish club".
- Members who say they have powers are Sweet 'n Spicy (money), Tarantula Head (lash at people with his hair), Dr. Y (wheelies), Asian Persuasion (manipulating people), and Queen Bee (her gun).
- To be an adviser for this club, it is a requirement to dress up as a superhero at least once a week.
- When Blaine Anderson was part of the Superhero Sidekicks Appreciation Club he was dressed as Robin from Batman, while in this club he took the alter-ego of Nightbird, character very similar to Nightwing, the superhero Robin became when he grew up in the DC Universe.
