"Feast, I am Hawk Moth. You have a consuming hunger that only the Miraculous can satisfy. I'm giving you the power to track them down, and devour every single one! But after you've swallowed up their owners, you must bring two Miraculous back to me — the one of Ladybug and the Black Cat!"
— Hawk Moth
When Master Fu's past returns to pursue him, he removes the Miraculouses from Marinette and Adrien to protect them. But they are ready to do anything to protect him, even to face a sentimonster without their powers! But while Fu wrestles with his past, Nathalie discovers the secret behind her awesome (and unstable) powers.
Tropes:
- Art Shift: Master Fu's flashback is shown in still, 2D pictures.
- Back from the Dead: After the heroes defeat Feast, the World-Healing Wave restores everything he ate... including the temple where the Miraculouses were originally kept and all the monks that lived there.
- Bathos: While Marinette wears a full-body biker's outfit with helmet to disguise herself for the intense high-speed chase, Adrien wears a banana suit. Also, they at one point try to delay Feast with the contents of André's ice cream cart.
- Bigger on the Inside: Feast's Stomach of Holding. Lampshaded by Cat Noir when he and Ladybug are Swallowed Whole.
- Bittersweet Ending: Although Feast is defeated and the Miraculous Temple and original Guardians are restored, Hawk Moth now knows Master Fu's face, meaning that Fu must go into hiding.
- Blatant Lies: Gabriel insists to Adrien that Nathalie's dizzy spells are nothing to worry about, but Adrien doesn't believe him because his mother had the same symptoms before her supposed death.
- Call-Back: In "Origins", it was hinted that legendary heroes of the past were actually Miraculous users. Here, Alya makes her own theory in that regard.
- Cassandra Truth: The bus driver refuses to believe Marinette is Ladybug out of costume when she tries to enlist his help, but he's entirely willing to help if it means saving an old man in trouble.
- Continuity Nod:
- When Alya explains her theory about ancient Miraculous heroes, she brings up the Egyptian Ladybug from "Pharaoh".
- Adrien uses the Mr. Banana outfit from "Kwamibuster" to disguise himself again.
- Dark and Troubled Past: As a young boy, Master was taken to a Guardian's temple and was set for training to be a Miraculous Guardian. Master Fu (then just Fu) hated it, cleaning the temple instead of being with his family and playing with other children his age. When he was tasked to watch the Miracle Box for twenty-four hours, he sat there, filled with boredom and hunger. He took the Peacock Miraculous to create a sentimonter to fetch him something to eat, but his hunger for food and his resentment towards his duty mixed together and instead created a sentimonster wanting to devour all the Miraculouses. Fu fled with the Box, and the sentimonter’s destructiveness led to the entire temple being destroyed, including all the monks and other miracle boxes inside. Fu lost the Butterfly and the Peacock Miraculouses in the snow, and never managed to recover them. He later fled to live in Paris, living under a secret identity.
- Dramatic Drop: The first sign that the statue is important is Nathalie dropping and breaking the tablet Gabriel is communicating through.
- Eat Me: Ladybug risks her own and Cat Noir's life by letting them both be swallowed, hoping that the amokitized object is inside Feast and not left behind in Tibet. The metal detector she gets as a Lucky Charm gives her confidence.
- Fantasy Helmet Enforcement: Marinette calls out Adrien's banana suit as unsafe for riding a scooter in, to which he responds that he's wearing a helmet and pads underneath it.
- Foreshadowing: Alix sarcastically suggests that there's a Bunny Miraculous, oblivious to the fact that not only is there one, but she's currently carrying it.note . Later in the episode, when Nadja reports the restored Guardians temple in Tibet, Gabriel alongside Nathalie watches the news report, and the scene switches to Tomoe Tsurugi listening to it and also Audrey Bourgeois watching it intrigued.
- Heroic Bystander: Because Marinette and Adrien don't have their Miraculouses, they must get help from locals, such as a bus driver, Captain Roger, and André the ice cream man to try and delay Feast.
- Heroic Sacrifice: Master Fu's plan to save the heroes is to take all the Miraculouses and run, expecting to be caught and devoured.
- Hidden Depths: Who knew Plagg was such a gifted pianist?!
- Ineffectual Loner: Master Fu's plan to deal with Feast is to take the Miraculous from Marinette and Adrien and lure the sentimonster away from Paris all on his own. However, the teens' determination convince him to give them a chance to fight it.
- Informed Ability: Master Fu mentions that Feast is immune to the power of Miraculous, but the episode never bears this out. Hawk Moth is able to beneficially empower him with an akuma, and Mayura demonstrates that she could destroy him if she chose to. Ladybug and Cat Noir fighting Feast doesn't demonstrate any specific immunity to the Miraculous, as he's the size of a house and thus would be resistant to physical attacks, and it's been previously established that Cataclysm can't kill a sentimonster regardless of who made it. It's possible Fu is simply projecting his own trauma onto it. In the flashback, his sentimonster was able to devour all other miraculous boxes stored at the temple, but it is never shown or stated that it faced a miraculous wielder in combat.
- Instant Costume Change: Marinette runs into her house to get her bike and seconds later comes out in a full biker's outfit complete with helmet, having been in pajamas previously.
- Internal Reveal:
- Hawk Moth discovers Master Fu's identity as the Guardian of the Miraculouses.
- Alya pieces together that there must be a Secret Order of the Miraculous and publishes her accurate theory to the public. The reappearance of the ancient temple at the end of the episode pretty much confirms it for everyone.
- It Has Been an Honor: Wayzz says this about being Fu's kwami right before it looks like Feast is going to eat them.
- It's All My Fault: It's revealed that Master Fu's mistake was using the Peacock Miraculous to create a sentimonster to bring him food during his training. Instead, the beast inherited his resentment of being a Guardian, which he never wanted to be, and was driven to devour the Miraculouses and all things related to them. It destroyed the temple along with everyone and everything there. The monks managed to give him the last Miraculous Box and the grimoire, only for Fu to lose the grimoire along with the Butterfly and Peacock Miraculouses as he fled his rogue creation.
- It Sucks to Be the Chosen One: As a boy, Fu resented being recruited to join the Guardians and taken away from his family and friends. Unfortunately, his resentment mixed into the Sentimonster he created out of hunger, making an insatiable beast obsessed with consuming the Miraculous.
- Make My Monster Grow: When Hawk Moth akumatizes Feast, it grows from the size of a small dog to the size of a small house.
- Mundane Utility: During his Guardian training, Fu was tasked with guarding a Miracle Box for 24 hours without food or water. His hunger eventually got the better of him, so he used the Peacock Miraculous to conjure a sentimonster to fetch some food for him. However, due to a combination of his hunger and his resentment towards the Miraculous for being the cause of it, the monster he created was given an insatiable hunger for Miraculous, leading to the destruction of the temple.
- My Significance Sense Is Tingling: Nathalie is able to sense the amok within the lava statue, realizing that it must be a sentimonster.
- Negated Moment of Awesome: At first, it seems like Fu will join the heroes in the fight against Feast. He gets halfway through saying "shell on" when his back gives out on him.
- Never Say "Die": While it's pretty clear that Feast ate all the monks, it's never stated directly in dialogue. However, there is a brief shot showing a shadow of Feast capturing a monk with his tongue during Master Fu's flashback.
- Nice Job Breaking It, Hero: Marinette thinks she and Alya did this because teaching Alya how to use a Miraculous ended up having her make the connections to the Order of the Guardians in the museum which she then reported on the blog which in turn apparently led Hawk Moth and Mayura to Feast. However, it would have happened regardless as Nathalie was there when Feast was unsealed and reacted to it. Likewise Hawk Moth already knew about the Guardians well before hand because of info from his kwami and his possession of the grimoire.
- Pet the Dog: When Plagg sees how upset Adrien is by Nathalie's dizzy spells (which reminds him of his mom's dizzy spells before she disappeared) he plays a lively piano duet with him to cheer him up.
- Pre-Sacrifice Final Goodbye: Master Fu gives a tender parting speech to Wayzz before he gets swallowed by Feast.
- Really 700 Years Old: Master Fu had been on the run from the "Feast" sentimonster for over 170 years, roughly half a century longer than any normal human has lived.
- The Reveal: We finally learn Master Fu's Dark and Troubled Past, and how he lost the Peacock and Butterfly Miraculouses along with the grimoire.
- Running Gag: Yet again, Master Fu starts to transform but it's interrupted (this time, it's due to back pain, just like the first time).
- Sealed Evil in a Can: Feast was trapped in lava when attempting to devour the last Miracle Box. Once Nathalie and Gabriel realize this, they free it from its prison then empower it to hunt down the Miraculouses.
- Shout-Out: Plagg and Adrien playing the piano together is very similar to a scene of Rhapsody Rabbit and The Cat Concerto, with Adrien as Bugs Bunny/Tom and Plagg (ironically) as the mouse/Jerry.
- Sigil Spam: Alya notes that various statues and paintings of historical figures she suspects to be old Miraculous heroes all have the same symbol on them, which is the same as the one on the Miraculous Box. Feast also has it on his head.
- Stomach of Holding: Everything Feast eats is sealed in its stomach. When its destroyed and Ladybug uses her World-Healing Wave, everything is restored to normal, including the temple and its occupants Feast ate nearly two centuries ago.
- Super-Persistent Predator: Feast; it has an undying hunger for Miraculouses, and stops at nothing to get them. Hawk Moth then gives it the power to track Miraculouses, allowing it to hunt down Master Fu.
- There Is Another: There are many more Miraculouses aside from the Miracle Box in Master Fu's possession. For every concept there is, there is a Kwami and Miraculous for it. And now that the temple is back...
- This Is Gonna Suck: Cat Noir, who's generally supportive of Ladybug's craziest plans, is visibly annoyed and disgusted when he realizes that Ladybug's plan to beat Feast involves being Swallowed Whole.
- This Page Will Self-Destruct: When Wayzz takes the Miraculous from Marinette and Adrien, he leaves them letters from Fu that self-immolate upon being read.
- Trainee from Hell: Wang Fu was this to the order. As he resented having to train to become a member of the Order of the Guardians, his resentment against the Miraculous he was forced to guard and the order created a monster that destroyed the entire order and tried to devour all Miraculous.
- Wham Line: According to Adrien, his mother used to have the same dizzy spells Nathalie is experiencing, all but confirming that the broken Peacock Miraculous is responsible for Emilie's current state.
- You Are Too Late: Marinette tries to talk Alya out of her exposé on the secret society connected to the Miraculouses, only for Alya to admit she already uploaded it. Marinette muses under her breath that Hawk Moth will likely learn of it soon enough, which he does.
