Had the series had more seasons, they would have featured...
- Kodiak Bear vs. Alaskan Moose
- Spotted Hyena vs. African Wild Dog, and the matchup would have whole packs on each side rather then just one-on-one.
- Killer Whales vs. a Humpback Whale.
- Elephant Seal Vs. Leopard Seal
- Indian Rhino vs. Gaur
- Komodo Dragon vs. Water Buffalo: Since the show was made when it wasn't known they were venomous, that wouldn't come into play for the dragon.
- Wild Boar vs. Black Bear
- Dog vs. Coyote: In a Formula-Breaking Episode, they'd actually be able to bring in one of the subject animals (whtever dog breed selected in question) rather then mechanical models.
- Tibetan Mastiff vs. Snow Leopard
- Caucasian Shepherd vs. Asiatic Black Bear
- American Bison vs. Texas Longhorn: scenario for the fight would be an stray bull from a ranch wanders off and encounters a herd of bison and ticks them off.
- Golden Eagle vs. Eurasian Eagle Owl
- Bald Eagle vs. Sandhill Crane
- Orangutan vs. Sun Bear
- Wedge-Tailed Eagle vs. Red Kangaroo
- Cat Vs. Red Fox
- Bugs vs. bugs (such as Tarantulas, Scorpions, and Centipedes)
- The series finale? Human beings, with melee weapons being tested (though for balance, guns nor bows are forbade).
- This troper made a full 12-episode hypothetical list of what Season 2 might have been like.
