I An Italian Dragon Ball channel made a video about EML, I asked him if the Italian version of the magazine also stated that Super Saiyan Dai San-dankai was 10x stronger than SSJ1.
The website has a page called: The Weekly ☆ Character Showcase, every Tuesday, they present the biography of a character from the franchise, whether from the manga, anime or film. And yesterday the character of the week was the Supreme Kai of the South (anime version).
Well, I wanted to know...
First evidence:
In a dialog between Gohan and Piccolo, Piccolo says that knowing Goku's personality, he will fight the mysterious opponent in the first match using all his power.
Second evidence:
Anyone who has the game could send me images from the game's encyclopedia about the new DLC: Story (including notes) and characters (only Goku, Uub, Vegeta, Goten, Trunks, Pan and Piccolo).
