Angle Draw Sphere (also known as AxAyAzSSS or just ADS) is an original character for M.U.G.E.N made by pkrs. It is a very cheap character, being known to defeat cheap characters, such as the 2nd Death Star. It is the first known character to KO A-Bomb.
This character takes the form of a black sphere with a small crater in the center. It is mainly a proof of concept character that demonstrates that M.U.G.E.N supports the possibility of projectiles and lasers that are aimed at enemy characters, instead of being fired at specified angles only. It also shows that such attacks can be set to continually track the position of an enemy character or be aimed only at launch.
However, there are also many other proof of concepts showcased here. These range from the mundane (background effects and switching backgrounds) to much cheaper abilities, most notably the ability to reverse reversal hitboxes. This final feature allows it to devastate regular cheap characters and those designed to outright instant kill their opponent at the start of the match.
