Well, my Eeve, Hero of lvl 100, was hard to train and...keep. It help that Luke my Lucario was able to befriend it and keep an eye on it. He holds an everstone of his very own that he found on our walk through Johto, and he loves that it. His very own rock that he brags on about. I think, he can take care of himself, if not, Luke won't stop until he finds his companion for life.
