A Leaked Footage of Dragon Ball Super: Broly x Tokyo SkyTree Has Been Revealed!
Well, nothing about Broly was revealed and it is just maybe a promotional thing to hype up the fans. I am pretty sure they wanted to refer ‘Broly’ as the fighter with ‘tremendous power’ or someone with the ultimate power. Then, Frieza asking about the secret to Saiyan’s strength also relate to the Origin of Saiyans theme of the upcoming movie. Also, below you can see all the other stuff that was revealed in the Tokyo SkyTree event! Enjoy!
