Rage Amped Luke (ROTJ) vs Office Palpatine (ROTS)

Fight takes place in Palpatine's office 30 feet apart Luke is dark side/rage amped like in ROTJ and stays in that mode the entire fight Sheev is in character same as when he was in the office duel. Cannon feats and scaling only for this fight.

Bump

I don't think Palps Lightning gets significantly more powerful from ROTS to ROTJ so I'd still say Palps wins that way eventually, if he just doesn't win in Lightsaber combat.

Bump.

Base Luke already wins mid diff

There is nothing specific that says he does in canon, but logic would indicate it did. Palpatine had decades to hone his craft and fully research the dark side, something he did not have during the prequels. Stands to reason he did get stronger.

However, Canon Luke has some of the best force feats in canon, pre-ROTJ.

Would have to back Luke here personally.

What happens to Luke is detailed in the second clip of the OP.

Canon: Luke.

Legends: Sidious

Base Luke wins and Sidious is fractionally slower from Dark Side degradation

...Please tell me this is Canon, not Legends. If it's Legends, he gets annihilated.

Palpatine.

Canon really has Luke with 2 years of training above Anakin and Mace, yikes.

Luke

Luke stomps

Sheev. Luke‘s strength could be a problem but Sidious has every other advantage

Even with the most absurd Vader scaling you can imagine, Luke gets utterly spanked.

OP says Cannon feats and scaling only for this fight.

Oh, thank God.

Luke still gets annihilated.
