The Ace Attorney games are filled with shout outs. They can be almost from any popular sources, especially in the English translation.
These Shout Outs range from Phoenix telling Franziska "Well, excuuuuse me princess!", to a security system named "S.P.A.R.D.A", to a clown who sings the intro of The Fresh Prince of Bel-Air.
Please, if you are writing an example, try to be as specific as possible to the reference, while also marking out appropriate crucial spoilers. Being vague about it is something we should avoid. Also, please try to keep this page as organized as possible.
The Steel Samurai is about half reference, half parody of tokusatsu shows like Kamen Rider, though once it gets the Iron Infant that it carries around in a cart, it becomes a full on Lone Wolf and Cub reference.
There are multiple references throughout the games to earlier investigation serials like Perry Mason or Sherlock Holmes. Unlike most other references on this page, these were usually in the original Japanese dialogue as well.
In the final case, where a crucial piece of evidence is a handprint on a piece of brown leather: "Hey, I think I've seen that on a shirt, before."
Ema suggests there should be letters in the detective's IDs if you examine Goodman's ID card and suggests a possible ID.
Phoenix: "A name and ID number are written here. "Detective Bruce Goodman, ID# 5842189"." Ema: "I wonder why they only use numbers for IDs." Phoenix: "What else would they use?" Ema: "Letters, silly! They're the reason we have a written language in the first place!" Phoenix: "True..." Ema: ""Detective Bruce Goodman, ID: YABADAB". See? Wouldn't it be better?" Phoenix: ""YABADAB"? Well, it does have a certain ring to it..." Ema: "Exactly my point! Tee-hee!" Phoenix: "(It doesn't take much to amuse her.)"
In the same case, there's this chat upon examining the Parking Lot B Block:
Show Maya the photo of the Steel Samurai after the first day of trials and Phoenix quotes Alice in Wonderland.
Phoenix: [Will Powers] doesn't seem the type, does he. (Curiouser and curiouser...)
The Gatewater Hotel becoming famous for an illegal wiretapping operation. The hotel name and the event reference the Watergate Complex in Washington DC, which lent its name to the scandal that brought down Richard Nixon (although the real thing is today just apartments and offices, back in 1972 one of its buildings was a hotel).
In Case 2, Detective Gumshoe asks if you remember his name. Choosing one of the wrong options nets you this gem:
At one point, it even has a weird internal shout-out by Maya suggesting Phoenix spice his name up by calling himself "Naruhodo A. Wrighto". "Ryuuichi Naruhodou" is Phoenix's name in the Japanese versions of the games.
And in case you're wondering why the o is shorter in the version proposed by Maya, "Naruhodo"(short O) literally means "I understand" or "I say" in Japanese and is Nick's nickname in the Japanese version.
Ace Attorney: Trials and Tribulations
Judge: "I-I'm a spoon!? I'm no spoonybard, I'll have you know!"
The CD from Furio Tigre's office and the virus it contains is labelled "MC Bomber." When Maya tries to remember the name later she comes up with MC Screwdriver and MC Hacksaw, but doesn't quite hit it.
When uselessly presenting evidence to Sister Bikini, the conversation with her goes like this:
Bikini: I don't know anything about it; I don't care about materials things. I'm some sort of immaterial girl.
Probably the same guy who sang Gumshoe's other favourite, "No motive, no crime..."
If you examine the other side of the Suspension Bridge, Maya will suggest to Phoenix that he should train with her, since it would be great if he could have spiritual powers too, leading to this comment:
Phoenix: "But then a miracle happened. The kind people like Mr. Tigre like to say never happen."note A localization hiccup in the bad ending of the second game included the line "The 'miracle' never happen," which underwent Memetic Mutation.
An easily overlooked one, because you have to pretty much intentionally mess up. But when cross-examining Dahlia Hawthorne, if you pick the wrong choice towards the end of one cross-examination, Phoenix will exclaim how his intuition was wrong. Godot responds: "Intuition...? Truthiness has no place here!"
Capcom also does a shout-out to its less-known survival horror series, Dino Crisis. The first DC game took place on Ibis Island in "The Republic of Borginia." Two key characters in Apollo Justice are from the Borginian Republic, suggesting a very bizarre intercontinuity canon.
Judge: I do hope this latest accusation is well-based.
Phoenix: (I wouldn't have put it quite so lyrically, but it's true.)
Apollo shows some theatre prowess by referencing Oedipus the King when you examine the back of the brooch found on the floor of Lamiroir's dressing room:
Apollo: A sort of pin-fastener for attaching things to clothes. Not a safety pin-type, though.
Trucy: So if it's not a safety pin...
Trucy: ... is it a danger pin!?
Apollo: I suppose if you stuck it in your eye, then yeah, sure. note For those who don't get it, using his mother's brooch pin, Oedipus stabbed himself in the eyes and made himself blind. It becomes Hilarious in Hindsight later when you realise the full truth of the brooch's owner
Ace Attorney Investigations: Miles Edgeworth
Several Internet memes have appeared in Investigations, including, but not limited to: Over 9000, "relevant to my interests", the Badger Song, etc.
In case 2, there's a bit of an internal reference, where examining a few books will eventually lead to reading about a "working name" for iFly Airlines. That name being GoYou Airlines. GoYou is the name of the airline in the Japanese version.
"It's a cage inside a cage that is this prison cell. It's like... Cageception!
In case 4, Edgeworth comes across a lit up model of a pony that "Sparkles in the twilight". He also doesn't get the suggested contradiction in a winged unicorn.
When Kay suggests that the hidden 51st floor might be accessed by a secret portal, Ray tells her that it's not the time to be thinking with portals.
During another point of case 4, Kay is losing hope due to being framed as a murderer and since she's lost her memory, is almost sure that she's done it and is asking Edgeworth to give up on defending her. Edgeworth replies by telling her: "If you don't believe in yourself, believe in the me that believes in you!"
She also describes the monster as the fiercest creature "this side of the Pacific Rim"
Likewise in case 5, presenting a Moozilla-related piece of evidence to the largely uncooperative John Marsh will cause Kay to unsuccessfully attempt to bribe him with candy in order to make him more talkative, causing her to remark that even her candy crush attack didn't work.
After a small spat between Justine and her son John, Edgeworth quips that children don't understand their parents. Kay counters that sometimes the reverse is also true.
In the second trial, the murder weapon on first glance bears a striking resemblance to Yuna's summoning staff.
When Athena stumbles upon her first dead body, Phoenix remarks that she turned five shades of pale... but at least it wasn't fifty.
A former pro wrestler becoming the head of a community. Not the first time in a Capcom series.
Also, a wrestler and mayor who is very much a Papa Wolf.
Athena later suggests to Apollo that he should also become a pro wrestler and adopt the moniker of The Amazing Firebrand.
While in court, Florent L'Belle's green hair dye job combined with his pale skin, purple suit, and cologne-spraying flower makes him look a lot like The Joker. His expressions and mannerisms are especially reminiscent of the incarnation from The Dark Knight Returns.
However, said purple suit combined with his normal sculpted blonde hair and the fact that he owns a line of cosmetics suggest that he may also be based on a certain other comic book villain: Adrian Veidt.
This bit when Filch is under suspicion of having been at the crime scene (And he never told anybody.)
Trucy suggests that Phoenix and Apollo form a comedy team called Agni & Rudra. This could be a reference to the names of the two ultimate dragons in the first Breath of Fire I, or two bosses from the third Devil May Cry.
Or more likely a reference to the two Hindu gods, Agni and Rudra, which the video games are also referencing.
When using Athena's emotion matrix for the first time in case 2, if you pick the wrong emotion, Athena and Apollo's ensuing dialogue is the first few lyrics of Comfortably Numb.
In case 5, Phoenix says "Failure is not an option here!" to himself. Made all the more appropriate by the fact that the case involved a space mission gone wrong, two if you count the related one that happened seven years prior.
The whole "HAT-1 Miracle" is pretty much a direct Shout-Out to Apollo 13. A space mission where the astronauts miraculously survived despite several major problems that was later made into a movie.
