Tac Nayn (aka T-9 Tacgnol) is the evil twin of Nyan Cat. He is a black-furred cat with a belgium waffle body, and a rainbow with different shades of gray behind him. His name is the backwards spelling of Nyan Cat, and his signature music is the Nyan Cat theme reversed. He also has dark red angry eyebrows, red eyes, a white frown, but keeps Nyan Cat’s pink cheeks (in a darker shade). His background is red with floating skulls, contrasting Nyan Cat’s blue with stars. Nyan Cat supposedly defeated him on Nyan Battle, but he is still alive. Tac Nayn also killed Donut Pusheen on Nyan Battle. T-9 is probably the only Cat that could’ve defeated the Nyan Cat, but the Donut Pusheen saved the Nyan Cat.In the Nyan.cat (website),He is till flying to the left but the rainbow looks like he’s flying backwards.
