Frieza vs planets of superhumans
Frieza vs ALL of the Namkien race and all of the saiyan race (excluding Goku, Trunks, Gohun, Vegeta) that was on the bardock saga... the entire planet full of Saiyans.
They are aware Freiza is on the planet and everyone has gathered around to confront him (everyone is transported to planet Namek).
Frieza can not destroy the planet and every 30 minutes that past he is reverted down to a lesser form. He starts off at his most powerful form... 30 minutes pass he goes down to his next form.
Can he win this?
