Does this count?
In the Lapis Ward Pokemon Center there's a guy who talks about The Savage. The story he gives there is pretty brutal, but it's not completely made up.
When Reborn was an on-line Pokemon league, there was a real guy calling himself Savage who ran a mono-Water team. All well and good, until he gets to Shade -- and finds, to his horror, he has absolutely nothing to counter his Shedinja. Presumably, once you submitted your team for the League, you couldn't make any changes without starting all the way over, from the beginning. So this guy throws himself into fight after fight, and loses every time... he did eventually beat him, but it came down to a PP-stall war. Unfortunately the logs are lost, I was only told this by another user.
