Who will win Lssj3 Broly vs Bills?

Answer 1

Bills.

Proof: Akira stated that Super Saiyan God is stronger than a Super Saiyan 3. Means Super Saiyan God Goku is stronger than LSSJ3 Broly, Legendary or not, makes no difference.

When Goku turns into a Super Saiyan 3 against Bills, Bills easily flicked him with a finger and he actually defeated him without even breaking a sweat. So if Goku, in his SSJ3 form, can't beat Bills, then there's no way Broly can have a better chance against him.

(If you're one of those Broly fanboys going to justify Broly by claiming that his power's growing then it won't work and it's already stated because if Broly's power do grow, wouldn't he turn into a Super Saiyan 3 in the Movie 10, it's obvious)

Not just him, even Ultimate Gohan, who is stronger than Super Saiyan 3 Goku can beat him.

LSSJ3 Broly is only around Kid Buu Level, but only weaker. Kid Buu would able to beat him too.
