It's also confirmed that some of the creatures stated will have the ability to transform into different "forms" based off a variant/deviant monster relating to them. Some forms will obviously be stronger in other monsters compared to others, but regardless they usually give the creature a boost in strength, agility, etc, as well as possibly a small height/length increase. Most are based off existing forms, but a few are of my own. More info on the custom ones will be announces at a later date.
