I've got tons of ideas for model animations if you want them. I've got most of the major pokemon games, so I can help out with any animation questions you might have.
-Sceptile line: The first stage primarily fights with its tail. The other ones are made to be like raptors, so attack animations involving their claws (all 4 sets) would be the best to go with.
-Charizard line: Attack animations involving claws and breath attacks would be best here.
-Venusaur line: If you can make vine like extensions on these guys, you could use the vines to make whip attacks along with some tackle attacks.
-Meganium line: See above.
-Blastoise line: The first 2 stages primarily fight with their heads (or shells) and breath attacks. If you can put a joint at the base of the cannons, they can move for projectile attacks.
Feraligator line: Fights mostly with its bite, claws, and breath attacks.
-Steelix line: Fights with tackles and by slamming its massive tail.
