He most likely has done very limited training at best. You guys are missing the point. If Gohan can become a Super Saiyan 2 with rage, of course Broly could too. That fact that his body brings out this transformation has to mean that it is for a reason. To be worse than the standard goes against his character. You guys realize Broly is way superior to Gohan right? If Broly fucking trained like Goku and Vegeta, jesus fucking christ, he might be fighting Beerus one on one or some shit. Broly's potential is unreal. Vegeta without super specialized training was 18,000. Broly without specialized training was in the 100 billion range.
