Ink Cat can down a bottle of liquor in a seconds, regardless of what form he takes at a time. He also has a rather high tolerance, not showing drunkeness until he's been at it all night.
Note: Ink Cat has many powers as a cartoon character that I realize might just be a little too powerful. Then again, it depends on what gifts other people have. So I'll list Felix's surreal powers, as they were in the cartoons, and if they don't sit right, I'll just limit it to Tail Shenanigans or something like that.
Ink Cat's tail is very flexible and useful. It can stretch and he can use it manipulate objects. When surprised or confused, Ink Cat's tail will become an exclamation point or a question mark. He can also remove it from his body and use it as a club, or shape it into something else, like a cane or a rope. He can even spin it very fast like helicopter blades. Link.
*Cartoon Form*Symbol Power:
There are a few times when something that Ink Cat does or something that happens around him is represented visually as a symbol. For most cartoon characters, these would simply disappear, but for Ink Cat, these are solid, and the cat can use them in a variety of ways. This includes the Zs that appear above his head when he's sleeping, the musical notes that appear when he plays music, and thought bubbles. When a question mark is not utilized, as often happens, it politely dissipates as Ink Cat moves on to the next thing. Of course this power is limited to worlds where these visual representations are present, such as comic books or cartoons.
Like Tail Shenanigans, Ink Cat's other body parts can be removed- for instance he can remove the top of his head as if it were a hat, and this causes no pain, discomfort or injury to him. These are just seconds long gags, however, and his body always reverts to the recognizable Ink Cat form. He also has limited shape shifting- able to take on the form of an object of similar size to himself as long as it's black.
Ink Cat can make his body narrow to fit through small openings, or he can hide behind something only a line thick, such as a street sigh. It's not the same as shrinking himself as well, rather he is so flexible that he simply makes himself fit into impossible spaces. I'm sure anyone who's had a kitten has seen them do something like this.
Similar to Symbol Power, but to the objects already in the world. The cat can sometimes cause an object to change into another object as long as the two look similar when drawn in ink. For instance, a deck of cards, being shuffled, can become an accordion, or a large flower can become a dress.
Hard to explain, but in his Felix cartoons, perspective means nothing. Things have a third dimension only so long as it's useful to the characters. Ink Cat can reach out and grab a door that's really behind him and several yards away, but he somehow bends the space so that it's within reach and only a few inches tall. He can take a hold of the horizon line in his hands and manipulate it- which overlaps with Symbol Power.
*Exceptions*The Plot Necessity Clause
: Of course, any of these powers can be negated when needed for plot or tension, or just for the rule of comedy. (What he believes to be) his home world is alive, and has much control over him as he has over it. It's just a back and forth.
The World Clause
: All of these powers are also dependent on just how cartoonish an animated world is. While Ink Cat will appear as a cat in every world that is animated in a two-dimensional style, not all of his powers will be allowed. For instance, given how King of the Hill is pretty much a sitcom in ink, he'd have no powers there, but in the Looney Tunes-verse, he'd probably have a lot.
In his human form, Ink Cat loses all of his surreal cartoon powers but for his epic drinking abilities. He does still have the ability to move, think, walk around, jump, fight, smile and can pretty do all the things an able bodied young man can do. There is one advantage over his cat form and that is that he has a voice and he can talk without the aid of speech bubbles.
*Out of Internet*
Ink Cat also has a curious amount of trivia about useless things, such as animals, linguistics, English and American history and certain TV shows and books that are from the future as far as he's concerned. He has no idea why this is.
