Uh...weird, I don't remember going to Johto...or really anything from when I was 9...

(this gap in data is based on the fact that my Gold version was stolen and written over by some mean twin girls who lived down the street from me at the time D< and I had a shiney Gligar at the time too TT^TT so IC, something terrible happened to Aaron while on his journey through Johto that caused him to loose all his pokemon, his Gligar became a monster and he is so tramatized that Prof. Palm has to use Drowzee to wipe his memory, with the data deleted for good messure)
