Rattata helped me own my rival's level 74 Empoleon. XD It could have owned it, but then it wouldn't have been level 1. (frowns) So technically, I could have owned Empoleon, but I didn't want Rattata to level up. XD
About my Torterra and Gyarados owning a level 100 Infernape, I was battling my cousin who had a level 100 Infernape (that I trained!) and it was a double battle. I had already knocked out the rest of his pokemon and only Infernape remained. I'm pretty sure that Gyarados used waterfall and Torterra used Earthquake and owned my cousin's Infernape. (sighs) Fond memories.
