Spellcasting
Cait has an inherent talent for spellcasting. He has offensive, defensive, and healing spells in his arsenal, allowing him to adapt to the needs of any given situation. Smaller scale spells take little time to cast, and can be done with simple gestures. Large and more potent spells take time, focus and preparation in order to cast them successfully.
Veils
Cait is able to create illusions, an inherent ability shared by all of his kind. He can use these illusions to become invisible to the naked eye, to conjure the image of people/objects/creatures, or to alter the area about him. Handy for concealing his presence/the presence of others, or for causing a chaotic distraction.
Shapeshifting
Cait's natural from is that of a black and violet striped Cheshire cat, but his shapeshifting ability allows him to change his appearance to whatever he chooses, including the cat boy form he uses for hero work. Human, animal, mineral, it doesn't matter so long as he knows what it looks like. The more intimate he is with the subject he's changing into, the more accurate the shapeshift. He's capable of taking on any gender he chooses, but more often than not he tends to stick to male gender.
Feline Physiology
Cait's body is built for agility, flexibility, stealth and speed. This is certainly the case when he is in his true feline form. He is able to orient himself in midair so that he always lands on his feet, a feat he can accomplish no matter form he is in. He can reach speeds of up to 30 miles an hour in short bursts. His clavicles float in his musculature and he has a compressible rib cage, like any normal cat. This allows him to squeeze in and out of tight spaces. When in humanoid form, he loses out on some of his physical prowess, but still maintains some benefits. While his speed is not as pronounced, he can run faster than most normal humans. He is double jointed in many areas, which gives him a good deal of flexibility.
Feline Senses
Cait's senses, especially when in feline form, are greater than that of humans in many cases. He can hear a full two octaves higher than a human, allowing him to pick up on high pitched noises that would otherwise go unheard. His ears can also swivel to help him locate the source of the sound. His sense of smell is roughly a thousand times more sensitive than a human's. His pupils dilate in a manner that gives him an almost panoramic view, giving him heightened peripheral vision. He is also able to see in ultraviolet, allowing him to pick up on visual cues that would otherwise be missed without advanced equipment. True to cat form, he has incredible night vision. When in humanoid form, most of these sense remain unchanged, save for his sense of smell, which becomes significantly dulled.
