Watch Nintendo's latest Super Smash Bros. tournament live right here

Mario punches Pikachu. Link slashes Samus. And that’s just the cosplayers fighting over swag in the parking lot of the San Diego Comic-Con! Inside that huge event, Nintendo is having those characters fight in the first ever tournament for Super Smash Bros. on the 3DS — and it’s happening right now.

Nintendo is gathering together Comic-Con attendees to battle it out in a big tourney for the upcoming four-player fighter on its 3D portable. The company previously held an invitational competition for Super Smash Bros. on Wii U at the Electronic Entertainment Expo tradeshow in June, but this is the first time the 3DS version — a similar-but-different Smash Bros. — is getting its turn in the spotlight. The portable game is due out first on Oct. 3, and the Wii U release will follow later this year.
