- Alternative Character Interpretation: Was Sirhan Dogen serious about threatening to have Patricia Roland's family killed? Or was he just being pragmatic and lying about it so he could blackmail her, given his established distaste for needless killing?
- Base Breaker:
- Kay, particularly among those who like the first three games best. Even her detractors, however, have sympathy for her in the 4th case of the second game.
- Justine Courtney. Many people love her for her unique design and her takedown of Blaise in the 4th case, as well as doting behavior for her son and, to a lesser extent, trying to help Sebastian. Many others hate her because she enables Sebastian's poor decision making, and is generally a huge bitch towards Edgeworth. Even her fans hate her behaviour at the beginning of the 4th case, when she dismisses herself as a suspect, then uses evidence she is fully aware is fabricated to pin Jill's murder on Kay.
- Complete Monster: Big Bad Quercus Alba is the head of a large smuggling ring. The other criminals of the game (except Lance) ''answer'' to this guy. He is the one who ordered the deaths of Cece Yew and Byrne Faraday and killed Mask*DeMasque II and Manny Coachen with his own hands. His reasons for these killings are as follows: Cece Yew was a witness who needed to be silenced, Byrne Faraday was a member of the Yatagarasu whose goal it was to expose his operation, DeMasque II was going to steal his fake statue and, with it, some plates used for a large-scale counterfeiting operation, and Manny Coachen because he ordered DeMasque II to steal it. Manny ordered the theft because he was planning to betray and usurp Alba and was unaware that the fake statue had been switched with the real one.
- Disappointing Last Level: Most fans criticize "Turnabout Ablaze" for dragging out the final confrontation way too long. That entire interrogation alone takes at least about two hours. And just when you think it's finally over, it's not. This eventually makes the ending more tedious than satisfying, compared to the other games which had much better climaxes. And even without taking in account the final boss, some fans argue this finale simply doesn't get you invested like the others do.
- Subverted with the 2nd game's final case. It is paced much better than Turnabout Ablaze, only having one real road bump near the beginning only because it was tying up the loose ends from case 4 rather then dealing with the current murder at hand.
- Draco in Leather Pants: Most fans seem to only acknowledge Knightley's Pet The Dog moments with the Big Bad while glossing over his more unlikeable qualities.
- Ending Fatigue: While you have to give the Big Bad of Investigations credit for being so tenacious, two full gameplay segments devoted just to cross-examining Alba is too goddamn long.
- Ensemble Darkhorse: For someone who appears alive in only one case in Investigations 2, Horace Knightley is popular with the fans. Mostly because of his relationship with the Big Bad. Funnily enough, his Japanese name contains the kanji for 'horse'.
- Colias Palaeno is also rather well liked due to being genuinely helpful and cooperative to Edgeworth's investigation, as well just being a Nice Guy.
- Escapist Character: Kay Faraday is what many Edgeworth fan girls dream of being. She's a cute 'modern-day Robin Hood' and gets to play assistant to Edgey, who feels a deep connection to her because of the parallels between her father's death and his. She's also Gumshoe's very best friend.
- Even Better Sequel: Gyakuten Kenji 2 aimed to be bigger and more dramatic than the original, evident by the "final case" feel that the first case of the game was shooting for (and achieved).
- Foe Romance Subtext: Shi-Long Lang and Edgeworth in Investigations.
Lang: (to Edgeworth) My ignorant little pretty boy.
Ha ha! You're sending the biggest chill down my spine, Edgeworth..!
- There's also Edgeworth and Calisto Yew.
- "Funny Aneurysm" Moment:
- Any time in the fourth case where Edgeworth defends Manfred von Karma's actions.
- And in the sequel, Raymond makes several jokes about von Karma upon his introduction. Even Gumshoe considers them this. Turns out he was invoking this trope deliberately, as he still believes Edgeworth and von Karma are Not So Different.
- To a lesser extent, that ice cream salesman. He waits just long enough to convince you his is just a cameo appearance...
- Harsher in Hindsight:
- Many people considered the reveal in the Apollo Justice game that Ema failed her exam and thus didn't achieve her dream quite harsh. With that knowledge, play case 3, where she appears as the same highly ambitious Genki Girl she was in the first game.
- in 2, People cutting off Sebastian mid-sentence, clearing their throats to make him stop talking, having his testimonies called stupid by Gumshoe and Larry, and Franziska whipping Sebastian for being stupid gets much less humorous after the end of case 4 where his own father berates him in front of everyone else that everything he brags on about was actually thanks to Blaise's influence and nepotism, and that he's too stupid to be his son for not even realizing it and a shame to his dad. Even after that, just a mere few minutes later he was kidnapped and woke up in his own garage, leading him to think that his dad's men kidnapped him on purpose and really does hate him.
Sebastian: You don't understand, Mr. Edgeworth! I lost everything I had this morning! *cue 5 Logic Chess pieces*
- Hilarious in Hindsight: Edgeworth's knowledgeable defense of The Steel Samurai sounds a lot like the way adult fans of a certain other kids' show (which debuted in 2010, a year after this game) justify their love. There's something priceless about the realization that, in his world, Miles Edgeworth is essentially a brony.
Edgeworth: It's a show geared towards kids... however its high production values and riveting plot draws in a number of adults as well.
- Ho Yay: Gumshoe declaring that he'll show Edgeworth how much a man he is, and Edgeworth responds by asking if he should prepare a 21 gun salute now or later.
- Internet Backdraft: The sequel not being released in the West due to the first Ace Attorney Investigations selling poorly. Fans are still clamoring for it to come stateside. At least a translation came over.
- Love to Hate: Simon Keys, the Big Bad of the second game, is such a scheming little bastard that he's overly entertaining and satisfying to take down. He's also a rare example that overlaps with Jerkass Woobie.
- Magnificent Bastard: The Big Bad of the second game certainly qualifies. He manipulates everyone and everything including Edgeworth to achieve his goal of revenge on targets that include former chief prosecutor and a president(well, his body double but still) and succeeds at taking down all of them, while covering tracks so well that in the end he's just one piece of evidence away from becoming Karma Houdini. All while maintaining innocent facade the whole time.
- Memetic Badass: Detective Badd. He might as well be the Chuck Norris of Ace Attorney.
- Memetic Mutation:
- Most Annoying Sound: Quercus Alba and Calisto Yew's Objections are both particularly annoying, as Alba's is really low and demonic whilst Calisto's sounds just whiny and weak. Not to mention the sheer lack of any personality or interest in the latter's voice. Portsman's coat swoosh also falls into this for some. Blaise Debeste's frequent weeping is constantly leading to him emptying his goggles with a splash, which some hate as well.
- Narm: Justine's "panicked" animation is supposed to be dramatic but it looks...more sensual?
- Player Punch: The second game has several. First, in Case 3, having to confront von Karma over evidence forgery as Gregory can count as one to players who know what it will lead to, similarly to being forced to present forged evidence as Phoenix in AJ. Case 4 begins with what looks like an attempted murder of Kay, her showing up heavily injured with amnesia... and then being accused of murder. And finally, in Case 5, finding out the real killer is Simon Keyes, someone who not only had Edgewoth's complete trust before, but who Kay considered a genuine friend. The moments before the big reveal are especially heartbreaking, with both Kay and Regina practically begging Edgeworth to prove it isn't true, and even Edgeworth himself being reluctant to believe it.
- Rescued from the Scrappy Heap: Franziska, particularly in the second game. The first game has her very concerned for Larry's son (although it turns out to be a doll), and extremely sympathetic and even downright kind to Kay after she loses her father. In the second game, she's very sympathetic to Sebastian once he realizes how awful his father is. When Edgeworth gives up his badge and being harassed by Justine and Sebastian, she whips the latter into submission and lets Edgeworth speak. Her conversations with Edgeworth, Kay, Gumshoe, and later, Sebastian, also round out her rough edges and give her plenty of depth.
Franziska: However...once must be able to accept their father's mistakes, no matter how much they look up to him.
- Ship Tease: From the second game, Raymond and Kate. From their first meeting, Gregory reminds him to 'note', not 'dote'. They clearly hold each other in high regards, though Raymond won't hesitate to suspect Kate when the evidence clearly points to her.
- Squick: In case 3 of the second game, the lyre of the Gemini sherbet statue was coated with a mix of salt from a salt rock lamp and the killer's blood. It was then eaten by two unknowing people.
- That One Boss:
- Dammit, Quercus, GIVE UP ALREADY! This guy has to be the most annoying boss-examination ever.
- In AAI2, it's the Logic Chess battle against Sebastian. It's the longest and most annoying Logic Chess battle in the game.
- Blaise's in the previous chapter is almost as bad, it's long and requires several actions you never needed to do before (such as going back on previous lines of questioning only to find options that weren't there before) and has to be ended by selecting the one option that penalised you every other time you tried it. Fittingly both battles are the only two in the game to use the "Allegro" version of the Logic Chess theme, and are family members.
- To a lesser extent, Lotta Hart's during the fourth case. The battle itself isn't that hard, but the clock runs down at a far faster rate than in any other Logic Chess battle in the game, meaning that any mistake ends up being much more damaging.
- They Wasted a Perfectly Good Plot: Though it feels unfair to bring up any aspect of the end of the sequel's fifth case as this, the Big Bad raises a particularly interesting legal question: can (or should) a chessmaster be held accountable for murders that he has deliberately manipulated other people into committing if there is no direct incitement to kill or other (provable) criminal activity on his part? Unfortunately, rather than answer that question, Jumping Off the Slippery Slope occurs when it turns out he actually did kill one of the victims himself and the case reverts to the traditional task of finding scant pieces of evidence that prove wrongdoing.
- Unintentionally Sympathetic: True, Patricia Roland ultimately brought the combined threat of Sirhan Dogen and Simon Keyes upon herself after her past misdeeds, but her motive (She killed Horace Knightley to eliminate a potential threat to her and her family's safety, as well as to frame Dogen so he would have to be transferred to a maximum-security prison and no longer have the ability to be a threat.) is difficult to fault, given its self-defensive and Mama Bear-ish nature.
- Unintentionally Unsympathetic: Justine is supposed to come off as merciless to lawbreakers and stuck in a very compromising situation involving Blaise coercing her and her nephew being kidnapped. But this is before she spent three cases hindering Edgeworth's investigation, using forged evidence to convict an innocent girl, and generally just being a giant bitch.
- The Untwist: Blaise being evil in the second game doesn't come as much of a surprise, considering their appearance and the fact their attempt at being Faux Affably Evil only make them come off as downright creepy. And the fact the only other suspect in the case is Kay Faraday. Of course, the real twist is just how evil they turns out to be, and the game's actual Big Bad is much more well hidden.
- What Do You Mean, It's for Kids?: Investigations 2 was rated 12+, even with the horrific material and the increasingly disturbing murder methods.
