NOTE: Difference between the beastlings and the metamorphose power. The beastlings only have part of the animal and usually those physicality attributes are permanent (Take Inuyasha as an example) As for the Metamorphose power, you can transform into a different person or into different kinds of animals.
Since angels and Drakens transform into; in the first case a big bird or have wings, and the second into dragons; this isn't part of the metamorphosis powers, again they are automatic attributes set for those Races. Same goes for the lycan transformations.
