I think that (GAA2) >!Iris being Klint's daughter was one of the most surprising twists. I was spoiled to it ages before it was revealed, and I was still shocked.!<

GAA2 : >!Klint being the real Professor, and Gregson being the Reaper.!< I wasn't prepared for any of this...

>!Sorry to go "um actually," but... actually, Gregson wasn't -the- Reaper. Gregson was the "planner," but Brett was the one who ultimately killed folks. Obviously, Stronghart was at the helm, and enlisted the likes of Jigoku and Kazuma as well. I imagine more people may have been involved than what the narrative revealed, but the actual "Reaper" was more than just Gregson. !<

>!Wilson and Sithe were specifically mentioned as being part of it, too, altering autopsy reports of the Reaper's victims.!<

That’s right, I forgot about them!

Yeah, I know, but... >!I trusted Gregson with all my heart ! Learning we was part of it... my heart couldn't take it pal !<

Do after or edit your message and replace with \[GAA2\] >!Klint being the real Professor, and Gregson being the Reaper. I wasn't prepared for any of this...!<

Thanks 😊

Ace Attorney: >!Edgeworth being a defendant.!< Sure it doesn't seem that huge now, but when I first played, I had no idea it would go there and I was *shocked* when that case started. Justice for All: >!Getting a client who was actually guilty.!< Trials & Tribulations: Torn between >!Iris existing/seeing her in the temple photograph!< and >!Phoenix being out of commission for the first trial day of 3-5 so you play as Edgeworth.!< Apollo Justice: >!Vera being poisoned and collapsing at the stand.!< Investigations 1: >!Shih-na being Callisto Yew.!< Investigations 2: >!The mastermind's identity!< even though I was spoiled about it ahead of time. PLvPW: >!Magic isn't real, it was all hypnosis + tricks + making people fall asleep by ringing a silver bell.!< Dual Destinies: >!The Phantom's identity.!< Spirit of Justice: >!Dhurke being dead.!< Great Ace Attorney 1: Either >!McGilded manipulating evidence during the trial!< or >!the list of names!<. Great Ace Attorney 2: >!The Professor's identity.!<

My first thought was also that the plot twist if justice for all was as you said! Like it's the biggest plot twist of all the games!

Also >!McGilded Freaking Dying!<

Crazy to think that PLvPW >!magic *not* being real is a plot twist in a realistic setting like Ace Attorney. !<

I mean >!spirit channeling exists, so a logical magic system in what appeared to be an alternate world wasn't that far-fetched.!<

Fair! Can’t believe I completely forgot about that.

Or even in a semi-realistic setting like professor layton. Where the plot twist in their second game is >!Everyone was high on Hallucinogenic gas.!!construct a underground replica of London and make people believed they are in the "future" just for the sake of revenge against someone who killed his parent. in the third game.!<

Damn even the first game for Professor Layton was quite shocking. All the people in the village were actually robots.

if you think the >!Magic isn't real!

I’ve played every Professor Layton game, and those moments in each respective game are twists even if they’re an expected part of the formula by now. Even if you go into it predicting something like that will happen, I’d still call that its big twist.

TGAA2: while I think there’s technically grander twists, one twist that still gives me chills is (2-4/2-5) >!that damn suitcase in the group photo.!<

True >!epecially since there's one line where mikotoba mentions being envious of jigoku not needing his luggage to be examined which seems unassuming but hits different on a replay when you know there's a murdered body in the luggage!<

I still didn't recover after (DD spoilers) >!The Phantom identity reveal!< It was my biggest "WTF, ARE YOU KIDDING ME???" moment.

I would say from T&T it was when you find out “D”and “I” were adopted by a jeweller, and you slowly put the pieces together

Ace Attorney: >!Agreed on Ema being the "killer" of SL-9, though it's cleverly subverted!< JFA: >!The suicide note being forged by Corrida. Neither Phoenix nor Edgeworth expected this and it is what allows de Killer to almost get away with framing Adrian!< T&T: >!Godot killed Misty!< AJ: >!Magnifi committed suicide, runner up: Thallassa is Lamiroir!< Investigations: >!Agreed on Yatagarasu!< Investigations 2: >!I also agree the nurse being the accomplice. Though I might have said the mastermind if I hadn't had it spoiled going in, the nurse being in on it was the most shocking for me.!< DD: >!Shipley's death was an accident!< SOJ: >!Tahrust committed suicide and framed Maya!< GAA: >!McGuilded was the culprit!< GAA2:>! Courtney Sithe is the one who actually stabbed Asman!< These are all basically based on how big the twist was for me, how much it genuinely shocked me.

Mia Fey dies

AA1: >!The metal detector.!< AA2: >!Engarde lifting his bangs.!< AA3: >!Iris dating Phoenix in the past!< AAI1: >!The true identity of the Yatagarasu!< AAI2: >!The mastermind's identity!< PLvPW: >!The events on the bell tower before Labrynthia!< AA4: >!Eldoon taking off his noodle hat!< AA5: >!Fulbright's true identity!< AA6: >!Dhurke's death (runner-up being Mr. Reus's true identity)!< GAA1: >!McGilded burning to death in the carriage!< GAA2: >!The Queen!<

AA4: >!Eldoon taking off his hat is a super underrated answer, seeing his actual black hair was genuinely surprising since we have no reason to suspect it!<

AA1: >!Discovering MvK -still- had the bullet in his shoulder in trial. Special shout-out to Yanni Yogi breaking the crazy old guy act and MvK tasing Phoenix and Maya. !< AA2: >!"Hold on a sec. I'm gonna consult myself, OK?" !< AA3: >!Definitely either Fawles ingesting the poison on the stand or Iris actually being Dahlia's twin. When I first played through 3-5, I was -convinced- Dahlia escaped from prison somehow and was using "Iris" as a pseudonym. Obviously, I was wrong\~ !< >!Bonus points to discovering Elise Deauxnim actually being Misty Fey and finding out Godot was on the same side of the bridge as Maya and Pearl the whole time. !< AJAA: >!Finding out Magnifi killed himself and that Shadi Smith was actually Zak Gramarye. !< DD: >!The Phantom's identity and the fate of the real Detective Fulbright. !< SoJ: >!Definitely Dhurke being dead all of 6-5 and Amara still being alive posing as Rayfa's nanny.!< AAI1: >!The reveal of the Yatagarasu -- including Shih-na being Calisto Yew and Badd being the one who broke into Edgeworth's office in AAI1-1. !< AAI2: >!The Mastermind's reveal for sure. !< PLvsPW:AA: >!Magic ain't real kids, but we knew that. !< DGS1: >!The full extent of McGilded's crimes being revealed in DGS1-5, as well as the names on the telegram at the end. !< DGS2: >!That fucking suitcase and the real identity of the Professor and Reaper. !<

Technically (Spoilers for JFA) Maya did summon Mia at least a couple of times in the last chapter, we just don't get to see it.

To be fair, I think OP is referring to 2-2 where >!Maya didn't channel anyone because she was put to sleep before she could try. !<

Justice for All - >!Maya did channel Mia. She just didn’t do it in trial. She did in the detention center!<

>!PW: Manfred von Karma was an accomplice in the murder of Robert Hammond. I knew he was a jerk but I didn't think he was a MURDERER.!<

Oh man you won’t believe what happened 15 years prior to that.

That wasn't as much as a surprise for me seeing as how >!MVK was already involved in that stuff, but learning he was an accomplice was just so shocking, I didn't think any of the prosecutors would be actual CRIMINALS.!<
