Dooku and ANH Vader vs

Dooku and ANH Vader vs ROTS Sidious

Dooku and ANH Vader vs ROTS Yoda

These are two separate matches. Opinions as to whether the duo can defeat Sidious or Yoda.

Both matches are all out.

Vader wins both matches because he's the chosen 1 which makes him the strongest Sith ever

Well I think Tyranus is a top-tier saber combatant and powerful force practioner in his own right. Vader is nowhere near capable of challenging either Yoda or Sidious as far as lightsaber combat goes but he is quite powerful indeed with the force. Perhaps maybe superior to Mace Windu in the Force.

Where is the setting?

Anywhere you would like it to be.

Working together and Sidious is defeated.

No

Darth Vader has been stated to only have 80% of Sidious's power.

But's that's by ROTJ. This is ANH.

Was that ROTJ or ANH? Dunno...but either way Vader is quite obviously inferior to Sidious.
