Brutal AI

Brutal AI
Brutal AI is a well-knew AI that makes characters be agressive,combo even more than usual and win more power by attacking,it is kind of cheap,since it can make characters like Super Mario beat Sonic Exe.

It is a fairly common AI,present in Super Mario(Due to his attacks are easy to combo,it can make him deadly),Super Luigi(Same as Super Mario) and Will Of Prison Flame(A cheap Mario variation).

Brutal AI and Cheap AI
There's difference between the two:

Brutal AI prefer to use combos and make the enemy go to the edge of the scenary,and start beating up him,occasionally using specials and hypers,but experienced mugen players may discover how to beat that AI,and the Brutal AI becomes just a small challange for them.

Cheap AI uses specials and hypers whenever it is possible,they attack ussing OHKO moves and they tend to have some kind of charge power or be easy to combo,thus making him gain power in a major speed,there's almost no way to kill a Cheap AI character(Like A-Bomb),unless using characters that are even more cheap(Like God Of Chuck Norris V3) or characters that are programmed to have some sort of switch if a cheap character appear(Like 20000).

Trivia

 * Altough Brutal AI is some kind of cheap,it isn't considered cheap because there is ways to beat a Brutal AI character without using cheap characters.
