The Ace Attorney games are filled with shout outs. They can be almost from any popular sources, specially on 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 Baby that it carries around in a cart, it becomes a full on Lone Wolf and Cub reference.
The CD from Furio Tigre's office and the virus it contains is labeled "MC Bomber." When Maya tries to remember the name later she comes up with MC Screwdriver and MC Wrench, 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.
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: (Really? "I see dead people" sounds more like a cause for alarm to me...)
There's a reference to the Police song Roxanne in the same room.
Namely, when you examine a red siren Apollo tells Trucy not to put on the red light.
Gavin's song Atroquinine, My Love might be a reference to the Jethro Tull song Aqualung (which includes the line "Aqualung, my friend" quite a few times).
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.
Case 4:
Judge: I do hope this latest accusation is well-based.
Something similar happens in Investigations, when a young Franziska says that she will whip Yew into shape.
In case 5 of Investigations, Edgeworth says that Larry Butz has been the world's largest source of Trouble with a capital T.
In case 2 of Investigations, there's a bit of an internal reference, where examing 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.
Edgeworth: And where were you when you experienced this... calm?
Lance: Our family garden, of course! Where else could it have been!?
Edgeworth: (Well! Excuse me for asking! This child is more princess than prince...)
In case 2, examining the Mr.iFly Piggy Bank's writing will prompt Edgeworth into this comment:
Edgeworth: I've seen it a lot lately and it's been bugging me...why does [[http://en.wikipedia.org/wiki/Apple_Inc. no one know how too properly space and capitalize]] anymore...?
Unorganized
At one point, it even gives 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/ I say" in Japanese and is Nick's nickname in the Japanese version.
