Mace Windu and Anakin Skywalker vs. DE Sidious

Swap them out for the B-team vs. Sidious fight

Full knowledge

Vaapad Mace
Peak IH Anakin

edit - BONUS ROUND: Peak Mace and KF Vader

Sheev.

God Emperor Sheev Wankatine.

Sheev.

Eh, if it was KF Vader I could potentially make a case for the two winning, but IH isn’t strong enough for that and Mace definitely can’t beat Sheev on his own by ROTS. They need at least Yoda and/or someone else like the Outlander or unchained Vaylin.

Vaapad!Mace is sub-ROTS Sheev and Anakin only scales to Yoda via Dooku stomping who is only as powerful as ROTS Sheev due to knowledge, not power. So yeah, DE Sheev murks.

Sheev

Sheev stomps.

Sheev, duh

I don’t see the two overcoming him in any way.

The Emperor

Sheev effortlessly.
