The Champion is a trainer in Project Pokemon that you have to obtain the Champion Badge. As some of you may know, the Champion is actually Gary who for some reason has Arceus. To try and fight this trainer you ust defeat all of the elite four and enter the final room. When you beat him you get a plaque which makes you able to get more rare pokemon than the ones you can catch without it. For example, When you beat him the plaque makes you able to get Giratina and Spiritomb from Lavender tower.
that's all I have for right now.
p.s. I apologize for my friends editing this, one edit they made was the ditto and the Kentucky fried chicken with magikarps thing. I just wanted to make this page helpful for people.
