artificial intelligence ennemy (fight game)

Hi, i’m programing a fight game, and i want to know if somebody can help me, i want an artificial intelligence script for the ennemy,
my game is a classic fight game, 2 characters (you and the ennemy).
(Sorry for my bad english i’m french)
thank you to those who want to help me

if you can think of the players abilities, creating the functions that he makes, then the enemies are the same. Just call them at random.
