Furitve assimilation -
The user subconsciously nullifies the minds of others to easily merge into a group. Can walk into a restaurant and immediately assume a waiter, or go into a crime organization and assume a the role of domestic servant.
The user feels the general emotions of a society or group of people by having an internal social mirror. The user can mingle into any situation.
Doing it again,
Animal DNA assimilation - can transform into an animal-like state when they come into contact with an animal's blood.
edit Capabilities
In this state they take on the characteristics, abilities, memories and powers. They can also take the form of humans who's blood that they come into contact with.
Dangerous Side Effects
However it must be noted that by doing so the user is at the potential risk of having his/her mind overcome by the creatures memories and instincts. As a result the user may turn on his comrades and may never be able to return to his original state.
Also anyother DNA assimilation done prior would either be cancelled out, or (worse) build upon the newly assimilated DNA causing the user to lose more of his humanity.

THEY KNOW MY NAME!!!
edit: Lol, my powers own yours.
