Major Characters

Minor Characters


  • This is the seventh episode to be named after a Sentimonster, the others being "Reflekdoll", "Ladybug", " Mega Leech", "Guiltrip", "Optigami" and "Sentibubbler".
  • Prized possessions from prior episodes are seen here, such as Manon's Ladybug doll, Master Fu's gramophone, and so on.
  • This is the second time Markov gets akumatized into Robostus, following "Robostus". However, unlike before, he has different abilities this time and is cursed with anger unless Hack-San is destroyed.
  • The thumbnail of the official trailer features Robostus, making it the sixth one to have some other character other than the titular one on it, following "Ikari Gozen", "Félix", "Ladybug", "Mega Leech", and "Optigami".
    • This also makes Robostus the seventh character to appear in more than one thumbnail, following Mayura, Lady Wifi, Princess Fragrance, Reflekta, Malediktator, and Style Queen, as he appears in the one for "Robostus".
  • Alix and Kim are shown to still have friendly competitions at the Trocadéro together, following "Timebreaker". Not only that, Kim keeps doing dares that seem impossible for him to accomplish.
  • Nooroo mentions the events of "Robostus" to Duusu, telling him how the titular villain betrayed Gabriel and hopes if Robustus revolts again then they might be able to escape his control.
    • This also implies that not only does the kwami's personality influences their wielders but also that a wielder could also have an influence on the kwami. As Nooroo started to act like Gabriel being influenced to take drastic measures without even thinking of the consequences.
      • If that were to happen then it ran the risk of both jewels being damaged to the verge of being destroyed and them going back to their spirit forms.
      • If not and the jewels fell off Nooroo and Duusu could escape but they wouldn't be able to take the jewels with them.
      • Due to the lair being apart of the mansion Nooroo was probably thinking the missiles would make a big enough noise for someone to hear or notice the damage done to the house and call for the heroes or destroy the mansion enough for him and Duusu to escape.
        • Even they could escape there is still be a chance the defense system would still be activated and Gabriel would be defenseless to the verge being killed.
  • It's revealed that Markov plays chess with an André, but it's unknown if it's André Bourgeois, André the ice cream man, or another person named André.
  • When Shadow Moth sends out the akuma, he says almost the same line as when he akumatized Markov the first time.
  • In this episode, Alya uses the Ladybug Miraculous, becoming a new ladybug-themed superhero, Scarabella.
  • Unlike "Sapotis" in where Alya chose the name "Rena Rouge" very quickly, Alya had a hard time settling up with a superhero name for when using the Ladybug Miraculous. Before settling with Scarabella in the very end of the episode, she comes up with the following names:
    • Captain Bug
    • Wonder Bug
    • Super Bug
    • The Bug
    • Lady Luck
    • Bugella
    • Justice Spots
  • Scarabella's transformation is similar to Rena Rouge's transformation and uses a different rendition of Pigella's transformation theme, where it is mixed with Ladybug's.
  • Marinette did not transform into Ladybug for this fight, as she was captured by her parents who were under Robostus' control.
    • This is the second time where the supervillain is able to trap Marinette, following "Party Crasher".
      • This excludes many possible times in "Desperada".
    • However, she appears as Ladybug at the very end of the episode.
  • This episode is the second episode where someone else other than Marinette Dupain-Cheng holds the Ladybug Miraculous, the first being "Reflekdoll" with Adrien holding the Ladybug Miraculous.
  • This is the second time a villain appears while Marinette is on vacation in London, resulting in a Miraculous being redistributed, following "Startrain".
  • Like in "Stormy Weather", "Style Queen" and other episodes, Marinette actually did the right thing by giving her earrings to Alya; she saved Tikki from getting captured along with her.
  • This is also one of the few times Shadow Moth was so close to claiming victory.
  • The scene where Cat Noir and Scarabella are cornered by mind-controlled civilians is a direct reference to "The Puppeteer 2".
  • This episode revealed that Marinette writes a full list of tips on her phone for her superhero life.
    • However, it is unknown if she writes any tips related to her normal life, but it's most likely her phone contains tips on both her normal and superhero life.
  • When Alya tells Trixx "Cat Noir can't see him with her", Alya makes Trixx enters the yo-yo. This implies that kwamis can hide inside the magical yo-yo, just like the Miracle Box.
  • One of the several times where both Cataclysm and Lucky Charm were used twice.
  • This is one of the several times Cat Noir attempted to use his Cataclysm on someone else of his own free will.
    • This is also the second time when Cat Noir attempted to Cataclysm the Ladybug Miraculous following "Ladybug".
    • This is also the second time a Lucky Charm is cataclysmed following "Weredad" but unlike the trashcan lid due to the sailboat being bigger only the bottom part of the boat was destroyed.
  • Just like Adrien in "Reflekdoll", Alya says that she's always wanted to cast the Miraculous Ladybug, which she then replaces the "Ladybug" part with her own superhero name.
  • Ever since their introduction, this is the second time the Magical Charms are not shown, with the last time being "Sentibubbler".
    • However, unlike last time, the reason for this was because Alya was the one to use the Ladybug Miraculous, not Marinette. Because she is not experienced enough with that Miraculous, Alya was not able access the full potential of the magic jewel.
  • Marinette mentions her aunt Shu Yin, making this the first reference to the specials in the main series.
  • Marinette (a.k.a. Ladybug) took off for London and had a replacement without telling Cat Noir is the same thing he did to her in "Miraculous New York".
    • The last thing Cat Noir said to Ladybug was similar to how she felt about him when he went away in the special and also explains why Cat Noir wanted to know Ladybug's identity so he could always protect her.
      • His reasoning is also similar to Alya's in "Ladyblog" as they both wanted to help Ladybug.
    • There's also another reason as to why the kwamis had been waiting a very long time for an owner in Cat Noir's case, it implies that not only current or previous owners (especially disgraced heroes) may harbor emotional attachments to superpowers that once belonged to them but also to the people that use them.
    • At first Ladybug thought Cat Noir was sad, when she revealed her identity to Scarabella, believing she broke her promise to him in "Troublemaker", when actually she didn't and like in "Heroes Day" and "Origins" what she did was an emergency.
  • This is the second time Marinette defeats an Akumatized villain without transforming into Ladybug following "Weredad".
  • As Cat Noir, Adrien believing that Ladybug was attacked by a sentimonster or an akumatized villain is the same way Ladybug behaved in "Santa Claws". As well as referring to the events of "Antibug" and "Ladybug" and on top of it saying, "There is only one Ladybug and you're obviously not her". Which is also similar to what Chloe said to Sabrina in "Miraculer".
  • This is the eighth time Marinette and Tikki end up separated which previously occurred in "Princess Fragrance", "Sandboy", "Miraculous Shanghai", "Reflekdoll", "Weredad", "Kwamibuster" and "Sole Crusher".
    • This is the fifth time Marinette ends up separated from her Miraculous which previously occurred in "Ladybug & Cat Noir", "Miraculous Shanghai", "Reflekdoll" and "Feast".
      • And yet, the third time where she separated from her jewels willingly following "Ladybug & Cat Noir" and "Reflekdoll".
  • Longg saying, "I'll have you know that not even superheroes can fool their parents when they want to go on a vacation" implies that maybe a previous holder tried to pull off that same trick but whether that past holder is Longg's or not is unknown.
  • It is seen that Markov and Anne Jeanne Théoxanne du Bocquale are currently working together on a science experiment.
  • This is the second time Alya's thought process is shown following "Sentibubbler".
  • There is also another way that the link between the Butterfly Miraculous holder and their champions can be interrupted or disconnected if it was done from the outside by something or someone else such as their target being knocked out, unconscious or the target loses their awareness allowing that to happen which is a common weakness to those with telepathic abilities.


  • When Alya reopened her hand after Marinette left at the station, the keys Marinette placed in there with the Ladybug Miraculous are not there.
  • Mr. Cuddly is miscolored pink.
    • However, it's possible that it isn't specifically Chloé's doll, as one of Alya's Instagram posts shows Ella and Etta with a pink Mr. Cuddly-like doll.
  • If you look closely, Manon's dolls appear to be duplicated in Robostus' prison, even though Marinette has apparently made only one set.
    • With that it could be likely that Marinette made more than set or someone else admired the dolls and decided to have them manufactured so other kids could have their own.
