I voted J-E-N-O-V-A. Challenge is also a good theme.
This poll seems to be for special boss themes (i.e. excluding normal bosses and final bosses). Otherworld (well, an arrangement of it that wasn't released in the soundtrack) was played during FFX's final battle, and both Dark Messenger and One-Winged Angel were final battle themes. Beatrix's battle theme is there in the poll, it's called the Sword of Doubt.
