"Sidious destroying a fleet in a degraded clone body while missing a hand in an instant (Legends)

Vitiate draining Ziost

Nihilus draining Katarr"

Using legends feats is cheating, everyone is op in legends.

Yep. Also question ive had for a while. In legends is Nihilus the most powerful sith ever?

Not really.

His power to end life on a planet is more of a hax, it's not like he's the Sith version of Galactus.

Technically the most powerful would be the cloned body of Sidious in Dark Empire and the Sith Emperor with complete ritual.

Out of these: Anakin controlling the Son and Daughter.

Other: Luke moving a black hole
