April O'Neil (Sarah Michelle Gellar)

In TMNT (2007) April and Casey Jones are living and working together in a shipping firm, engaged in a relationship. It is she who finds Leonardo in Central America at the start of the film, having been in the area seeking an artifact for Max Winters. No mention is made of her past as a journalist, but it is instead implied that she has taken up archaeology as a career.

She has taken up martial arts training from Splinter, purchasing a yellow bodysuit with armor plating from Japan and becoming skilled in the use of katana, apparently leaving behind her past as a 'damsel in distress'. This is demonstrated as April and Karai fight it out while Casey, Splinter and the turtles battle the Foot in order to save Leonardo.
