See the floaty skulls floating around Tac Nayn,well those are part of his planet's atmosphere. The pure evilness of Tac Nayn and his alien friends. (that is if he had friends;3) The evil of him made the air like this. The planet he lives on (Tac-9) used to be earth-like and filled with Nyan cats until 2 nyan cats breeded a bad nyan,a Tac Nayn. The aura emmiting from Tac turned all nyans bad except for Nyan Cat. It escaped, leaving Nyan world to become Tac-9
