Trivia

 * Prior to the premiere of the episode, fans of Teen Titans Go! were asked to speculate what the so-called Opposite Titans would look like. Many fans drew various artworks of their own ideas for Opposite Titans, while other fans used an app on the Cartoon Network site to build their own Opposite Titan Team using ready-made illustrations. Among those illustrations were the actual Gender Opposite Titans from the episode.
 * Although Madame Rouge has previously appeared in the comics based off the show but this episode will mark her first appearance in the series itself.
 * It is revealed that the Titans have genderbent counterparts.
 * This episode has a similar title to a Season 2 episode "Beast Man".
 * This episode is also known as "Opposite Titans".
 * This is the first episode to premiere in 2018.
 * This episode will air and has aired on President's Day.
 * This episode reunited Cree Summer and Tara Strong as they did the voices of Susie Carmichael and Dil Pickles from Rugrats and its spin-off series All Grown Up!.
 * The other Opposite Gender Titans were voiced by Scot Menville (who voiced Gender Opposite Raven), Khary Payton (who voiced Gender Opposite Starfire), Tara Strong (who voiced Gender Opposite Robin), and Hynden Walch (who voiced Gender Opposite Cyborg)
 * Various Russian stereotypes are associated to Madame Rouge in this episode. She plans to replace all pizza with pierogis and borscht, her hideout appears to be modeled after Saint Basil's Cathedral in Moscow, and she traps the Titans inside of Russian nesting dolls.
 * Where the Gender Opposite Titans came from is still a mystery. But it can be speculated that they may have come through a mirror since Beast Girl mentions that she was looking at one before bumping into the other Titans.
 * This episode premiered in a block of other Teen Titans Go! episodes that had different kinds of opposite Titans, such as "Robin Backwards" (Bizarro Titans) and "Snuggle Time" (Super villain Titans).
 * Hynden Walch reprises her role from the original series of the voice of Madame Rouge.

Continuity

 * Some of the Opposite Gender Titans say catchphrases that sound similar to what the Titans normally say. Opposite Gender Raven casts spells by saying, "Mazarath Zetrion Tinthos", Opposite Gender Starfire said Zhama Lamma Shu-Mu, and Opposite Gender Cyborg yells "Yoobah", ( "Booyah" with the letters switched around.)
 * The Titans are able to recognize Robin's distinct cries and whimpers of pain as they are beating him up (thinking he's Madame Rouge). Robin did actually cry and whimper exactly the same way in a previous episode, "Squash & Stretch", when the Titans were beating him up to see if inflicting violence was funny.

Errors

 * One of the reasons Beast Girl thinks that she's Madame Rouge is that she likes pierogis. But moments earlier she had asked about who Madame Rouge even was, so it was not likely she would have known her eating habits.
 * Beast Boy's true origin story was briefly explained in the episode.

Running Gags

 * Beast Boy and Beast Girl thinking one another or themselves was Madame Rouge.
