To the average gamer without much knowledge of the series, the most iconic part of the Ace Attorney series is almost certainly the speech bubbles that pop up on the screen. Name every one that appears in the main series Ace Attorney titles.
This only includes bubbles that appear in the 6 main series games, and the game in which said bubble debuts in also disregards spin-offs.
One specific bubble is in Japanese, so just typing the letter O will work. I chose O because I’m confident everyone will get the first one right.
