LMFAO
This is unironically actually an interesting thread.
1. Ragdolling and toying with Mace and Oppress using a fraction of his power
Yes
2. Solo'ing the B-team within seconds while fighting Mace
Not sure if his fighting style would take them out as quickly, but I could still see him disposing of them very casually.
3. Overpowering Mace Windu and nearly overwhelming Yoda with Force lightning
I'm not so sure about that. Even if he can quickly learn Force lightning, he may not have the mastery with the technique to use it to the same potency Palpatine did. It's possible, but not clear.
4. Unbalancing the Force so much a prophecy is needed to stop him
I don't think he would know how to do that.
5. Creating lightning storms across the galaxy with his hologram
I wonder if that was more a passive reaction to Sidious's presence rather than a conscious effort on his part. I'm not sure if Vader would know how to do that, though he'd likely have the power to.
6. Shrouding the long term precog of the entire PT Jedi Order 24/7
He wouldn't know how to do that, and Sidious apparently has a special talent for it.
7. TP'ing and draining tens of millions on Byss 24/7 across the galaxy with minimal effort (initial Byss feat)
He probably wouldn't have the mastery to do it, though with some training he should have the power to..
8. TP'ing and draining 20 billion people on Byss 24/7 across the galaxy with minimal effort
He wouldn't have the mastery and that this point Palpatine is likely outright more powerful too.
9. Burying the Lusankya while mind wiping witnesses
This Palpatine is likely more powerful than Vader, but Vader may have the power to do the TK - not sure about the TP.
10. Destroying a New Republic fleet with Force storms
He doesn't know how to do Force storms, though he likely has the power to.
11. Force choking Dooku through a hologram from across the galaxy
I could actually see that tbh.
12. Beating Yoda
If properly motivated and in the right environmental circumstances, Vader should be able to win.
