LegendaryBroli

well yeah it is tough to say but they did mention broly was born with a power of 10,000 and for his own father to get a mind control device to try to control that power it seemed that broli's own power was multiplying over the years up to the fight with Goku in movie 8.

But if goku had turned Super Saiyan before broli's actual transformation and probably did, he would be credited as the legendary Super Saiyan.

However there lies the problem first vegeta stated that power triggers the transformation but then theres the statement "pure of heart" and "anger" come into play since vegeta went Super Saiyan himself after the frieza saga and at the time vegeta just wanted to be the top dog.

But for the sake of arguement lets say goku is the legendary Super Saiyan.
