History Videogame / SonicAdventure2

* DubInducedPlothole: Among many other examples (see Blind Idiot Translation above), there is the ending, in which Rouge originally claimed that she'll stop trying to steal the Master Emerald. The dub translated it as her saying that she's stop stealing altogether, which gets contradicted by later games, where she's still an unabashed jewel thief.

** Both {{Boss Battle}}s shared by Tails and Eggman take place when Amy Rose is technically in the immediate vicinity, but despite the repeat BeamSpam, MacrossMissileMassacre, and occasional WaveMotionGun, Amy's just fine. The rematch during the AstralFinale is a particular offender, given that there are enormous canisters of explosive chemicals nearby and the enormous panes of glass imply the room is especially fragile, but, nope, that room on the Ark is MadeOfIndestructium.

* NoEndorHolocaust: ''VideoGame/Sonic3AndKnuckles'' establishes that the Master Emerald is needed for Angel Island to float, and ''VideoGame/SonicAdventure'' is very, very clear that if anything goes wrong with the Master Emerald [[ColonyDrop the island will land like a sack of bricks]], but ''Adventure 2'' distinctly ignores the fate of Angel Island while Knuckles and Rouge are competing for the Master Emerald pieces, presumably to better sell them acting LikeAnOldMarriedCouple when Knuckles should rightly be furious.

* BigDamnHeroes: Shadow manages to teleport [[BadassInDistress Rouge]] (and three of the Chaos Emeralds, of course) off of Prison Island mere seconds before the whole island explodes.

** The Flying Dog does not appear to belong to a troop, [[TheLastOfTheseIsNotLikeTheOthers as it reports only to "headquarters"]], but directly takes the name of an animal.

** Almost every character is introduced in the middle of doing something--[[TheLastOfTheseIsNotLikeTheOthers the only one who isn't]] is TheHeavy.

** In order to keep either Knuckles and Rouge from collecting the others' emerald shards and ending the Master Emerald sub-plot too early, they don't encounter each other until the [[RivalFinalBoss after all their story missions have been completed]]. In order to make sure all playable characters have at least two {{Boss Battle}}s during the story, however, King Boom Boo appears [[GiantSpaceFleaFromNowhere from nowhere]] to give Knuckles a fight earlier on.
* InterruptingMeme: Some of the dialogue have characters interrupting each other's sentences right before they end it. This is due to the English vocal direction not choosing to match the lip flaps or timing in the games.

* YouJustToldMe: Eggman pulls a magnificent one on Tails and Sonic when they come to rescue Amy. Meaning, of course, that Tails was [[JustForPun outfoxed.]]

** The ARK was shut down because the GUN higher-ups did not trust Gerald or his research. [[spoiler:When they heard about the violent tendencies of the Biolizard, they used it as a justification and cover-up for their killing of the personnel, placed the blame on Gerald, and forced him to continue working under their scrutiny before executing him.]] This is explained in full in [[https://info.sonicretro.org/Sonic_Adventure_2_-_The_Truth_of_50_Years_Ago the Japanese version of the strategy guide.]]

** The OSHA would've had a fit if they set foot on the Space Colony ARK--the entire station is a giant death trap, most egregiously with its fragile air locks throughout the hallways.

* TheBadguyWins: The true ending of the game takes place after Team Dark’s victory, Eggman was able to start up the ARK using the Chaos Emeralds which ends with a warning alarm going off. The True Story begins shortly afterwards with [[spoiler:Gerald Robotnik’s final will being played, and both teams having to team up in order to stop his planet wide disaster from occurring.]] Whereas in Team Hero, the ARK is already in the process of being destroyed after Tails’ victory over Eggman.

*** Sonic first appears breaking out of a helicopter where he was being held captive[[note]]Sonic is notably the only character [[TheLastOfTheseIsNotLikeTheOthers not to share his introductory scene with another playable character]]--he shares it with G.U.N. itself, instead[[/note]].

*** Eggman appears first either in the Hero story interrupting Knuckles and Rouge or in the Dark story raiding Prison Island to unleash [[TheHeavy Project Shadow]].

** Unlike the Hero Story, which deliberately paces how new mechanics are introduced to the player[[note]]The player gets a Sonic level and a Sonic BossBattle; the player is then given Knuckles, who runs about as fast as Sonic and whose gliding technique acts like an alternate to the homing attack; the player is only then given Tails, who clunks around in his ChickenWalker and gets a BossBattle to follow[[/note]], the Dark Story throws the player into the deep end with an irregular set of levels and much less opportunity to get used to them[[note]]The first level in the Dark Story is an ChickenWalker shooting level, followed immediately by a BossBattle with Shadow and a Rouge level after.[[/note]]

** Sonic is imprisoned and taken to Prison Island, which just so happens to be where G.U.N. is holding the three Chaos Emeralds that Eggman and company attempt to steal.

* TheHeavy: Shadow dominates the story of the game, being introduced almost immediately, sharing connections with GUN and the Space Colony ARK, and giving Eggman his EvilPlan (and thus being responsible for parts of the story even not immediately related to ARK or GUN). Much of the game is a deep-dive into Shadow's backstory.

* AntagonistAbilities: It doesn't matter that Sonic's the FastestThingAlive, because TimeStandsStill on-demand with Shadow's Chaos Control technique.

* AntagonistAbilities: Shadow's all-new Chaos Control technique--it doesn't matter that Sonic's the FastestThingAlive if TimeStandsStill.

* NewPowersAsThePlotDemands: While Sonic uses the term "warp" to describe Shadow's first use of Chaos Control, the way it's presented in the cutscene suggests Chaos Control is being used so TimeStandsStill, freezing Sonic in place as Shadow rushes past, which is consistent with how Shadow's "Chaos Control" works in multiplayer. [[spoiler:During the AstralFinale, Sonic instead successfully attempts to use Chaos Control to {{teleport|ation}} from one enclosed space to another]].

* PlotHole: During the SecretFinalCampaign, [[spoiler:it's revealed that Gerald Robotnik went mad and became a MisanthropeSupreme after being taken into GUN custody, which raises the question of how he was able to program the Ark and the Biolizard still aboard to carry out his revenge while still in GUN Custody.]]
