In both Ultimate Alien and Omniverse, Gwen has shown the ability to transform to Anodite at will and not only when she feels extremely angry, sad etc. However she transforms into he Anodite form only in case of emergency, as if she use a great amount of her powers, while Anodite, she will forget everything.

Hope that helped :)
