Who could beat Lord Nyax in a fight?

Besides NJO Luke, could anybody beat Nyax in a fight? DE Sidious? Lomi Plo?

Most of those people?

Out of curiosity, how could most of them beat Nyax when he held off NJo Luke and a few other Jedi all at once?

Since neither Nihilus nro Nyax speak (well, Nihilus does. But presumably no one understands it...he probably communicates telephatically like Nyax)

The two would have a great convo.

Nyax: I want to eat people.

Nyax: I want that energy that is somehow under the Jedi Tmple.

Nihilus: I like lots of Force energy. I think I'll take it.

Nyax: Nuh-uh! I found it first!

*Nyax ignites all teh lightsabers*

*Nihilus drains him*

*Victory fanfare*

I doubt he could beat Sidious in the force.
PS: We can't choose more than 1 person in the poll...

Most of the people, plus Kyp, Exar, Sekot and more probably could.
