Here's a branch for guys who like to read about transformations in which the transformed becomes more bear-like. This includes hair growth, gains in girth, muscle growth, size changes, age progression, mental changes, attitude changes, etc...
The end result, however, may go as far as to make the transformed non-human like a were-bear, gorilla, Sasquatch, yeti, Neanderthal, beast-man, savage, wild-man, etc...
