That describes most of the characters in this arc not named Goku honestly.
Its probably one of the biggest faults of this arc with how the story has been framed with characters disappearing on multiple episodes only to come back later. No one has really done anything "exceptional" other than eliminate a couple of mooks for each episode.
I would at least hope we could move past "it's just for money excuse" though considering the arc is one big excuse in itself to give the supporting cast something to do. The one thing Freeza has going for him is his personality in comparison to certain other members on the team I could mention.
Sure, but at least the rest of the characters don't feel as forced into the arc as Frieza does.
The best thing about Frieza to me was how satisfying his defeat was, and him being brought back again and again destroys that.
It doesn't help that his interactions with other characters have been done in the most generic "villain playing along with the good guys" way. He's just been boring since the tournament started.
