Raditz vs Samuron

[KyuubiAhri]

can the potara fusion of Sauron and Saruman win?

 

[Captain Cadaver]

Via magic hax, they rape.
Via raw power, they still zero-diff due to Saruman getting Moon Level scaling from Gandalf equalling a Balrog, which aren't too far below Tilion, the embodiment of the moon. Even if taking into account Piccolo's Moon Bust, the power up Fusion brings would be enough for Samuron to easily solo the Saiyan Arc.

In their true forms, either of the two solo the Freeza Arc.

 

[Darker]

DBZ characters don't have any resistance against magic, so they wouldn't just stop at the Freeza Arc.
