Tusk

Tusk is a ‘Human’ who came from another dimension where all people look like him, he wants to destroy our universe and recruit people from our universe such as Karaka, Swift and Karo.

Tusk nearly destroyed our universe in S3 Ep9 but Carl managed to stop it from happening...

Tusk is believed to be more than 200 years old, as people in his universe live up to 1000 years old.
