"Eureka!" is an interjection used by Miles Edgeworth in Ace Attorney Investigations: Miles Edgeworth and Gyakuten Kenji 2 when he works out a clue at a crime scene. His father, Gregory Edgeworth, also used it for the same reasons.
- Japanese: "Kore da" (これだ！; literally "it's this").
- "Eureka!" only has voice acting and speech bubbles for Japanese and English. This is due to Ace Attorney Investigations: Miles Edgeworth not being localized in any other language, unlike previous Ace Attorney games.
Eureka is an interjection used to celebrate a discovery, a transliteration of a word most famously attributed to the Greek scientist Archimedes. The word comes from the Ancient Greek word "heúrēka" (εὕρηκα), meaning "I have found (it)".
