First game was Gold so ...
1.Did solo run with Feraligatr (only catching the legendaries and buying a dratini)
2.Used a Masterball on Ho-Oh
3.Encountered a shiny pokemon (paras) on the forest near azalea after hearing the old lady say that "the forest is watched over by its guardian", catch the shiny pokemon, run out of battery without saving, assume that shiny guy was the forest guardian, get new batterys, spend 8 hours searching for "the forest guardian", get new batterys and realize it was a random encounter. (man that paras still haunts me ... if anyone has a shiny paras from the forest please trade it to me)
