As for Diezel's sprite, most likely it should have been in order to show how he looks before the fight, as with Sleazy Hyena/Mahir in GT, it also hints at his direct gaze, unlike the look during the fight where he looks at Mezz. I didn't get my answer about Mezz's sprites, where he's completely naked, covered in semen, looking back and looking worried. (The path to such sprites is: www -> img -> sv_actors -> Mezzsluttyclothed.png; Mezzsluttynude.png; Mezzsluttynudeunaware.png)
I do not know if they are used or not, but at least I have not seen them in my walkthroughs of the game. Sometimes there were moments when the sprites changed very quickly, literally for an instant, maybe in those moments you can notice them.
And by the way, why doesn't the Sleazy Hyena/Mahir icon have a transparent background like other characters like Mezz and boars? Instead, it has a monochrome background.
