Regis: Regis, is an aging Mantis Shrimp fashion designer. He used to be a famous fashion superstar, but those days are behind him and he mostly runs a small boutique. Regis was born in an alternate history version of a post-World War II/Cold War era in where mutated humanoid animals were used to fight battles. However, Regis was more interested in fashion than fighting. One day, He and his twin brother Rebus found a dimensional portal that was being worked on by the scientists who created them. They touched the portal and were transported to a cartoon world. From there, he became famous. At some point in his life, he moved to A-Town while his brother currently lives in S-City. Regis believes he is the one to have the greatest fashion sense. He can be really catty and moody at times and will criticize the fashion styles of others. Regis is also very vain as he worries about being old. However, he does care about his friends and his boyfriend Terrance.

Den: One of Regis’ multiple exes. Den is a hippy hermit crab who runs a dispensary called Den’s Den in A-Town. He is mostly chill unless he is with Regis. They tend to be tense with each other which is why they broke up. They only still live together because Den feels bad for Regis. He is currently in a relationship with Steg, a monster child psychologist.
