Episode 23
Gilda And Meek #12 "The Code" (Un-Iverse #23)
The premise of superheroes is finally more formally introduced and explained in The Un-Iverse, as The Piranha tries out for a new superhero team and learns some dark secrets in the process. Meanwhile, Augatha successfully captures Gilda, Meek, Dr. Raggleworth, and Bernadette. And that's the B story!
There is a good chance many readers will feel ripped off by the end of this story. And I think MANY readers will find the turn of events sublime instead. Test your Un-Iverse mettle here, folks. If you are pissed, this franchise probably isn't for you. If you are delighted instead, you are in for some good times ahead.
Also, the second Meek's Chiller Theatre back-up story is the shortest, but also the most unusual, and done in a different art style.
