NIX

NIX is the protagonist of the whole plot of CATRIX, finding his missing human 'Butler,' Master JACK.

Nix usually behaves superciliously to others, but he is also a rational thinker in an emergency.

His impoliteness sometimes harms other agents’ heart, but his humorous and energy still makes other agents appreciate him as a great agent.

NIX’s fire element attack is so powerful that even he cannot control his power and often burns his tail.

NIX’s fur color used to be white, but he became gray due to an 'incident' from CATRIX.

If you want to see his past white fur, you can check it by playing Rags2Riches, the prequel game of CATRIX.
