Who can oneshot Darth Zannah?
This is a speculative thread for comparing and contrasting force abilities in the VS forum. With or without being amped and without referencing characters like. Valkorion, Luke, Sidious, Talzin etc.- what unamped force users could ragdoll or destroy Darth Zannah with lightning, drain, telekinesis, or telepathy? Have these characters successfully penetrated the barriers of other force users, and why do you believe they can oneshot Darth Zannah?

Depends.
A superior lightsaber duelist(I.e Vader, Dooku, Kun, Mace, and in the right moment, even Maul, Anakin, and Obi) can keep her backpedaling and outright beat her quite solidly, in a duel.
Force gets more complicated: Masters of Telekinesis(i.e Vader, Dooku, Mace, Galen, Revan, Jaden to an extent, and Caedus) would dispatch her rather casually in Force Power, mostly due to Zannah's less than impressive force showings. However add Illusions to the mix, and you have to look at each characters individually, in regards to Willpower, couple this with questions such as;
Does the character themselves know illusion based powers?
Have they demonstrated a resistance to/or something similar to illusions?
Have they studied holocrons? If so which ones?
The list goes on, and on, and on.
That's how I see it, anyway.
