I was a little surprised to see Frieza return in the storyline. But for the most part, I liked his story in Dragon Ball Super. Some of his old followers use the Dragon Balls to bring him back to life.
He trains and becomes a rival to Goku. Using his golden form and some trickery, he manages to defeat Goku somewhat.
But Frieza is horrified when Vegeta reveals that he can turn Super Saiyan Blue too.
But at the end of the day, Goku kills Frieza to prevent him from destroying the Earth.
Goku goes to hell to recruit Frieza for the tournament of power. Which was very awkward for all parties involved.
He does okay during the tournament of power, though he spends a lot of time hiding and just plotting nefarious crap.
Everyone was surprised to see Frieza granted his life back. Then he admits that he’s not going to change. You would think Frieza would learn by now.
