The trials and tribulations of a superhero kid and his evil twin.
The first great series to showcase on Newgrounds. Still a favorite!
A strange cartoon about a creature who loves to touch rusty metal.
Box against ridiculous opponents such as a hick, an old man, and a cross dresser to try to become number one!
If you are old enough to remember Mike Tyson's Punch-Out, this game is kind of like that, except with a bit of 3D movement and hand drawn looking graphics. The game features 10 opponents and 2 mini-games to strengthen your fighting powers. Each of the opponents has a different fighting strategy that you will have to figure out. If you get stuck, there is an awesome walkthrough that can help you out.
If you find any glitches or have any suggestions on how to improve the game, please let me know.
