A Mobian Coyote who used to have a cowardly streak, but grew to become a loyal steed to the Freedom Fighters. Antoine is a swordsman, very headstrong but subsequently particular about culture and class. Has an overexaggerated French accent alongside all that. Has become the love interest and spouse of Bunnie in most recent material.

I understand nobody can reliably be Rob Paulsen (because I know how much of a legend he is), so I understand if your take on Antoine isn't... that. In any case, I always imagined Antoine to sound a bit older than he did in SatAM anyways, so here are some voices that I believe could fit with that:
