This will take place after Broly is recruited into the Frieza force and before they go to earth, so on with it
Prologue: on Frieza's ship Frieza had called Paragus and Broly to the command center to have a word with them.
Paragus: You called for us Lord Frieza
Frieza: Yes Paragus, i have called you here for a job for the two of you
Paragus: Lord Frieza what is this job you have for me and Broly
Broly: stays silent
Frieza: i need you two to conquer a planet that is called earth
Paragus: you mean the planet where Vegeta is on
Frieza: no this is a different one, from what my scouts have told me apparently 80% of that world's population has special powers and some use their powers to be heroes and others use them to be villains, they aren't too powerful so i am sure Broly can defeat the heroes in some time
Paragus: my lord if the people of that world aren't too powerful surly a simple battalion of soldiers could conquer the planet
Frieza: Yes Paragus however this is a test for you and Broly to see if you are truly devoted to the Frieza force
Paragus: It shall be done Lord Frieza
Frieza: good because we are nearly there
