In B&W2, there's the Lion, Ape, Wolf and Cow. You also get the Tiger if you've ordered the Collector's Edition.
All the animals are pretty much the same, with the exception of their fighting styles. Some like the Tiger and Lion stirke fast but don't pack as much of a punch whereas creatures like the Ape are slightly slower, but much more powerful. If you want humour, go with the Cow as he can be quite funny. Hope that helps :: .
Well now....
The Lion is my personal favorite* i made it a liger as in half tiger half lion*
he is stron and can be agressive
Ok one thing in BnW 2 is that you can make your creature A war mashine or a cudly crazy cool pet.
all the animals are almost the same in strenght and smarts, but differ in agillity.
like a bad wolf can beat a good cow that hasent been trained to fight, but a evil bull *cow* that is buffed and mad can easily kill the wolf or anything else . hope i helped
but its better for you to find out and chose.
