Roy Killin, a guy who saves people from danger and leaves alone the people who can take care of themselves, he doesn't show up often, as soon as he finishes the person attacking, he quickly run away, no one knows why, he has no friends and doesn't spend time making any or taking the thanks he deserve, he has trained up his pokemon for years and years, making him a strong fighter.
in reality, his family was killed by a person who went attacking people, he didn't want that to happen to the others, so for the rest of his life, he went saving people and not made any friends, didn't even take the thanks, because he did it for himself, in his mind
He was walking along a lonely route near by of Fortress City,with all his pokemon out as usual
Roy enjoys walking in the woods and enjoying the nature, but if he saw any fights between pokemon or someone being attacked, he doesn't like it and he sents all his pokemon to stop them, he loves watching friendly pokemon fights,though
He suddenly heard footsteps running towards him, and he hid in a bush with his pokemon back in their pokeballs
[take the footsteps as you, if you like]
