You are one of the saiyans, and this asshole killed Broly's father just to trigger him more to watch the battlefield between Goku and Broly.. As Broly started to loose control, Goku took Vegata with him and went to Freeza, yelling out, "Have Fun Freeza!" And they both tleeported to someone meanwhile the triggered Broly appeared infront of Freeza.

"HANG ON! what're you doing?! I'm the mighty Lord FREEZA!" Freeza yelled out in fear and shocked as Broly started to beat his ass up, strongly.

Freeza had enough and immediately turned into Golden Freeza and started to fight with Broly, but it's no use. Due to what he did really did trigger Broly, so he was still beaten up in the volcano. "Augh!" He groaned, looking at Broly, before grinning, "..Hmm, look at this.. Your battle power is astonishing!" He says as Broly then saw someone started to fight with them.

Then you appeared, floating in the air as you saw that the once peaceful icey place became a literal volcano like.

Freeza's eyes widened at the sight of you, in disbelief and confusion why someone just suddenly appeared out of nowhere, "Who do you think you are..?"
