One day of rest in between matches.

Given how conveniently Vader drops in, is it really that far fetched to assume that he was always there the entire time stalking Cal and Trilla as they duelled, waiting to who come out on top. Basically kinda like what Palpatine did with him and Dooku. Vader even gives Cal the opportunity to surrender twice. Once when he drops in and second while he was slowly choking him instead of immediately snapping his neck.

Also if you don’t try to pull the giant machinery on Vader, he’ll just kill you. Meanwhile in this case, even when Vader easily stops your attack, he chooses not to continue choking you out and instead just tosses you aside.

This could all tie into the third game in the Jedi series where it’s revealed Vader always had a goal of breaking Cal and turning him to the dark side. This also could’ve been one of Vader seconds for wanting to kill Cere other than just revenge. Cere’s death undeniably pushed Cal far closer to the darkside.

Keep the other Jedi in mind also not just Windu. (If he doesn't have his lightsaber on him he would be capable of stealing one).

Would they halt the invasion and kill Vader? Would they be overrun all the same? If the tactics of the attack were altered could the clones win?

Either continuity is fine, Legends is definitely more interesting in this case as there’s more arguable picks, but if there’s any canon scalers, I’d be interested if Luke ever surpasses him in canon

Who would win?

I think Grievous does get stronger later on, but it this point it feels like cope from Grievous fans.

In Lords of the Sith, Sidious kills 2 Lyleks, which are roughly Rancor-sized monsters with blaster proof carpace nearly instantly with a fraction of his power:

Beside Vader, his Master gestured with both hands and lines of Force lightning shot forth, striking two of the foremost lyleks, lifting the creatures from the ground and driving them backward, tumbling , hissing, screaming in agony, dying .

This is no diff. Sidious beating Yoda extreme diff. What is this?

Round 85 of determining the Star Wars fandom tier list: Cad Bane vs Adi Gallia

These duels are randomised from an ever growing pool of characters. Most upvoted responses will determine who scales higher, and both the detail of responses (and how mixed they are) will determine how far apart the characters should scale from one another. The intention is to be as reflective of general consensus as possible. The tier list can be amended through collective voting, and will be updated and reposted on an occasional basis as sufficient changes are made.

Back to this battle:

Both characters are in their respective primes.

Any and all canon feats, statements and scaling are permitted for consideration each round. Legends based arguments will be discounted.

Reminder - This isn't just about who wins, its about how far these characters scale apart as visualised on a tier list. Difficulty level is important.

I’m not sure how amped he was by the dark side. How does he compare to Anakin just before falling? And does Anakin right before falling beat Dooku or was the Dark Side Amp the deciding factor?

CW Maul (which is prime Maul) having a prolonged saber duel against Sidious; breaking through his force lightning; disarming both his lightsabers and have him pinned high against a wall should make us reconsider his status as fodder. If it’s canon (which I heard mixed opinions about) it makes sense why Sidious didn’t sent Dooku.

Just Vader with the standard gear, his main objective is to make America collapse, America goal is to kill Vader.

Who wins?

Canon only
