Tac Nayn (pronounced Tac-9) comes from an alternate dimension where everything is the opposite of our universe. Nyan Cat's cuteness created an embodiment of pure evil: Tac Nayn! Every 22,079,460,347 years Tac Nayn's universe merges with our own in a battle for reality supremacy. Donning the evil belgian-waffle armor Tac Nayn cannot be harmed by our puny mortal weapons; only his arch-nemesis Nyan Cat is powerful enough to tear through his golden, delicious hide. This is why Tacnayn shouldn't be a girl.
