Characters that can beat Nihilus ?

Malak?

I actually think so... ^
Just wait for the roasting

Oh yeah, tentatively.

I have no idea why the early answers were so exclusive.

Do you think Marek could replicate Revan's feat of disintegrating Nyriss?

no

Honestly, yeah. I mean, Nyriss is impressive only because she could disintegrate some Force users on a nexus with a charged attack. I think it's fair to say that Galen is above that.

Also unless if you think Vitiate >>>>>>> Sidious, powerscaling seems to make that clear.

Note: Revan didn't just flick his finger and kill Nyriss; he redirected a very powered up attack she made herself. It's impressive but calling it a one-shot is kind of unreasonable.

Vader level and up.

The Star Forge's "Drain" has nothing to do with Malachor V's "Drain".

Eh, not necessarily. The way I see it, Darth Nyriss was channeling her energies for *twenty seconds*. Said energy was potent enough to disintegrate her or Scourge/Surik combined. Revan was capable of shitting out more energy than that in under a second, suggesting he could easily disintegrate her with his own power as well. I wrote a blog about it here: http://comicvine.gamespot.com/profile/darthant66/blog/revans-raw-power-overview/97193/.

I'm not sure if blocking an attack is analogous to being able to produce it yourself. By that logic, Revan > nexus Vitiate, since he knocked his bolts back at him.

That's with a lightsaber. Not comparable to Tutaminis at all.

There's still Starkiller advancing on Palpatine in that case. He could block Palpatine's lightning but couldn't injure him.

Also, Revan chose to use tutanimus instead of his lightsaber not only there, but also against Vitiate's charged attack. Was it actually the better option?

That's not a comparable example either. Starkiller barely contained Palpatine's Lightning - Revan bent Nyriss' back at her and destroyed her with it.

For the latter case, Revan's lightsaber got completely ignored at that point and it seems to be bad writing. That being said, he probably knew that it wouldn't work against Vitiate's charged-up Storm, so he decided to go for Force Absorption and suffer fourth-degree burns.

I don't think Revan would have used tutaminis if he thought there was another option. Vitiate's lightning might have been too powerful to block with his lightsaber. Of course that's speculation, but it's the only thing that makes sense.
