Well, let me make this clear;

I'm surprised there were no ads for an Xtreme 3... even if there were, I'd like to have a little say about the Maverick bosses.

The Xtreme 1 bosses were 4 from X1 and 4 from X2. When Xtreme 2 got announced, I thought the other missing Mavericks from the same games would be coming. But only 2 from each of the first 2 Super NES games came, and Blast Hornet, Volt Catfish, Overdrive Ostrich, and Tunnel Rhino stole the show-- uh, I mean, game.

So if any ads were planned for an Xtreme 3, I think only Blizzard Buffalo and Toxic Seahorse would have made it, and the rest would have been brand-new and never-seen-before, let's say: Diamond Cheetah, Dive Bullfrog, Elm Marten, Magma Vulture, Shadow Chihuahua, and Sword Skunk.

All the other Mavericks were modified after small creatures, and those Mavericks being in the game with Buffalo and Seahorse probably would lack in fun, balance, and difficulty, so that would make sense.
