I attempted to recreate it, and I used the save file I had from a few moments beforehand, but to no avail, it was a one time glitch... I will say that it scared me quite a bit, and that it gave me triple the most EXP that any other pokemon had given me from a battle at that point...
I guess just note that it was in the Ilex forest right after I beat the gym leader from the closest town... (I forget the town name for right now...) Thanks for the reply though!
