White Tiger resembles a tall and muscular humanoid in what is or may not be a white full body tiger suit with gray stripes and yellow eyes. In the dark, his stripes appear purple and his eyes green. However, his suit may actually be his real body, as his mouth was seen opening on his "mask" and he was seen licking his "fur". His nature as an actual feline is further enforced by the fact that his fur has the same allergic reaction on Major Glory that an ordinary cat's fur would.
Through all of his appearances he has never spoken a word, only making meowing sounds like a cat, leading some to believe he is incapable of speech or to question whether or not he is even really human. Despite being called "White Tiger", he acts more like a common house cat, doing things such as purring, playing with yarn, drinking milk, chasing mice, enjoy being petted, using litter boxes and clawing scratching posts.
White Tiger has been known to team up with fellow Justice Friends member Valhallen and both seem to get along like old classmates, showing that they have been friends for quite a long time. White Tiger has some hostility towards Krunk due to the latter's attempts to get of him for Major Glory's sake in "Can't Nap". Despite this, during their first meeting they seemed to get along well, like a little boy who had just found a stray kitten in his home, and he was one of the many who tried to remove a nacho chip from Krunk's tooth in "Pain in the Mouth" in order to end his tooth ache.
White Tiger possesses the power, speed, reflexes and claws of a tiger but each attribute is enhanced to superhuman levels. Allowing him to move at amazing speeds and cut down anything in his way to pieces with relative ease. His claws are so strong they can even cut the nigh-invulnerable Krunk, however they are powerless against the mighty and thick hide of the fearsome Badaxtra. While his speed and reflexes are superb, he was still easily outmatched by the invincible Rasslor. However, the fact that he was one of the few heroes summoned by Rasslor to represent his planet shows that he is one of the most powerful heroes on Earth.
