History Recap / BigHero6TheSeriesS1E21CountdownToCatastrophe

* AlternateAesopInterpretation: InUniverse, Obake interpreting AnAesop about Icarus his own way.

* EverythingsBetterWithDinosaurs: Globby turns into a ''Tyrannosaurus rex'' and a PteroSoarer while fighting Big Hero 6. Fred, naturally, finds it awesome.

* AdultFear: Aunt Cass is worried about Hiro's safety. Bonus points because she already knows what's like losing a nephew.

* RealityEnsues:
** Granville always knew the identities of Big Hero 6. It isn't stated exactly, but there had been previous comments from the team over how their faces were exposed.
** Honey Lemon finds a hidden wax cylinder recording from Shimamoto...that has at least a century's worth of dust and grime covering it. Wasabi had to spend a good deal of time cleaning it up properly for the open house.
** Hiro tries to ask for an extension on his project - he didn't even '''have''' an idea for it - but Granville refused. It was the end of semester, which meant there was really no extra time to get.
** Being a TokenGoodTeammate means that you are going to have standards higher than most of your team, so when the EvilPlan is to destroy San Fransokyo, Globby decides on a HeelFaceTurn, since it meant not just the destruction of millions of people, but the life of his only friend, Felony Carl.
** Because he has no super suit and is dependent on Baymax most of the time, Hiro is powerless when Baymax is BrainwashedAndCrazy and brings him to Obake's lair.

* VillainousBreakdown: After Hiro and the others save the city, Obake laments from his crumbling lair over how he could've rebuilt San Fransokyo into something "perfect". When Baymax offers to save Obake, the latter refuses and orders Baymax to return to Hiro. As Obake's lair begins to fall apart around him, he sits in his chair, resigning himself to his fate.

* AlternateAesopInterpretation: Obake asks Hiro "Why Icarus plunged to his doom?"
--> Because he needed ''better wings''.

* NotSoDifferent: Obake seems to think so, at least. Hiro tries to refute it, but Obake only has to point out the energy amplifier Hiro made (the same invention Obake tried to make in his youth) to make him hesitate. When Hiro perfects the energy amplifier, a purple glow covers the right side of his face similar to how a purple glow covers the left side of Obake's.

* ComicallyMissingThePoint: As Granville reveals Obake's past, all Fred gets out of it is "His name is ''Bob?!''"

* EverythingsBetterWithDinosaurs: Globby turns into a TyrannosaurusRex and a PteroSoarer while fighting Big Hero 6. Fred, naturally, finds it awesome.

** As Globby rampages through SFIT in TyrannosaurusRex form, he knocks down the "Open House" banner that falls down in front of him, recreating the iconic shot from the ending of ''Film/JurassicPark''.

* CollapsingLair: This is Obake's ultimate fate.

* InternalReveal: Hiro finds out Trina is a robot when he sees her in Obake's lair, with her head full of wires detached from her body.

* OOCIsSeriousBusiness: In Part 2, Hiro notices that Baymax ''didn't'' respond to him saying "ow" and finds Obake's chip in him afterward, and then ends up captured.

** When Hiro is about to enter the restaurant, he exclaims [[Franchise/Ben10 "It's hero time!"]], referencing the catchphrase of another Creator/ManOfAction creation.

** When Hiro is about to enter the restaurant, he exclaims [[Franchise/Ben10 "It's hero time!"]]

** When Baymax accidentally mentions Obake in front of Aunt Cass, Hiro comes up with a cover story that it's [[VideoGame/PokemonGo a phone-based video game where you need to capture "obake" creatures]].

* NotSoDifferent: Obake seems to think so, at least. Hiro tries to refute it, but Obake only has to point out the energy amplifier Hiro made (the same invention Obake tried to make in his youth) to make him hesitate.

--'''Krei''': What? Everybody lived.

* ComicallyMissingThePoint: As Granville reveals Obake's past, all Fred gets out of it is "Wait, his name is Bob?!"

* WhatHappenedToTheMouse: Trina and Noodle Burger Boy are left unaccounted for by the end of the three-parter, and it's unclear if they survived Obake's base being destroyed.

* ClarkKenting: Finally subverted when Big Hero 6 confronts Granville. She always recognized them in spite of their costumes. This was brought up in "Mini-Max" by Go Go that Granville is too smart for this trope.

* ContinuityCavalcade: There's various nods to previous events in the season, among them, Fred recreated the Kentucky Kaiju, Wendy Wower (who now has the title of Doctor) and Liv Amara are at SFIT for the open house event, and Honey Lemon and Wasabi go to Baron Von Steamer's lair from ''[[Recap/BigHero6TheSeriesS1E01FredsBroTillion Fred's Bro-Tillion]]'' to get a phonograph to hear Shimamoto's log. Granville's paperweight from the pilot is also revealed to have been Obake's failed prototype. Krei is still upset over his stolen wallet and that's what makes him agree to help with Big Hero 6's trap for Globby.

* TheReveal: Lenore Shimamoto's invention was the cause of the Great Catastrophe. She made a miniature star that collapsed on itself, creating a shockwave that destroyed the city. Obake (really Bob Aken, Granville's protegé who had the accident that made her resign) plans to recreate the Catastrophe in a larger scale (albeit one that is more controlled), so he can rebuild San Fransokyo as a city of science and investigation without any limits. The accident is revealed to have damaged the part of Obake's brain responsible for his sense of right and wrong.

** Honey Lemon finds a hidden reel from Shinimoto...that has at least a century's worth of dust and grime covering it. Wasabi had to spend a good deal of time cleaning it up properly for the open house.

Krei is still upset over his stolen wallet and that's what makes him agree to help with Big Hero 6's trap for Globby. About the only thing not referenced in the finale is some way is dance villains High Voltage.
