We previously gave you the heads up on a Guinness World Record attempt at SDCC by Bandai, Toei, Funimation and Bluefin to set the world record for the largest gathering of a Kamehameha attack and now we have the video. The assembled group shattered the previous record of 250 by gathering 786 DBZ fans.
Goku voice actor Sean Schemmel led the attack, ahead of today's 30th Anniversary Dragon Ball panel (which will have more on later).
