-There was a small invitational tournament during the event including 8 competitors from both the fighting game and Pokémon communities. The grand finals match was between Rip(Pikachu) and Justin Wong(Weavile) with Rip coming out on top.
The event was streamed on twitch.tv (although not all matches could be streamed obviously)
