Iacedrom and Ygbir

.

Iacedrom and Ybgir are more realistic-looking counterparts to Mordecai and Rigby respectively. Their names are "Mordecai" and "Rigby" spelled backwards. They first appeared in the episode "Dizzy," as a realistic looking blue jay and raccoon, respectively; also, they both wear top hats (similar to Pops) and they have semi-British accents like Pops. They meet Pops when he came to their world, Dizzy World, and gave him some ice cream, telling him that they outlawed speeches which is the reason Pops came there as it was also illegal to not enjoy ice cream. They later almost killed Pops when he gave a speech while turning his back on the crowd when Mordecai and Rigby encouraged him to and because he had broken the law; Iacedrom and Ybgir almost killed Pops and Iacedrom follows them when they escape but hits his head on the edge of Dizzy World and falls down apparently dizzy as he spiraled down to the ground.

Trivia/Goofs

 * They are voiced by J.G. Quintel and William Salyers just like the regular, yet default Mordecai and Rigby.
 * Iacedrom and Ybgir are the third villans in the show that Mordecai and Rigby have not destroyed or defeated but escaped from. The others are Moon Monster, the Coffee Bean, the Grease Monster, and the Graffiti Monsters. Mordecai and Rigby met the Moon Monster and Coffee Bean before Iacedrom and Ygbir.
 * Ybgir's name is also mentioned when Rigby had to say his name backwards during "Jinx".
 * Iacedrom can fly but it is unknown if Mordecai can. Iacedrom is one of the known bird characters that can fly.
 * Even though Ybgir is supposed to be Rigby's name backwards, it's pronounced as Ygbir instead of Ybgir.
 * Iacedrom and Ybgir are really only in Pops' mind and are personifacations of Pops' fear of speeches and a reference to Mordecai and Rigby as well as all the fancy dressed people at Pops' speech.
 * This was the first time and probably only time where Mordecai's name was heard backwards. However, Rigby's was spelled backwards the first time too but the second time was in "Jinx" when he unjixed himself.
 * They are Pops-like counterparts of Mordecai and Rigby.
 * It is unknown what happened to them after Pops, Mordecai, and Rigby were saved.
 * They seem to be the leaders or bosses of all of the dizzy zombies.
 * Dizzy World was in Pop's mind with Rigby and Mordecai, which means he might think of Mordecai and Rigby as fancy all the time.
 * Iacedrom is the backwards version of the name Mordecai.
