Terrestrial Metamorph: Mason has the ability to morph into any animal he knows of. He can change into extinct animals and even animals from different planets. When he changes, it only takes a couple of seconds. It doesn't matter how big or small. It does not put strain on him to do this. He can stay in an animal's form indefinitely. He has changed into multiple animals such as a swarm of fireflies and a group of barnacles. Mason can also change into a hybrid, which has all the animals' powers rolled into one. He can't control this so he doesn't turn into a hybrid unless absolutely needed.
Animal Mimicry: Mason has the power to mimic the abilities of any animal he knows of while he's in their form. The ability apparently gives him intuitive understanding of the animals and what abilities they have that may be useful in the situation.
