Typhojem survived an attack that erases a universe from existence. He was injured, but it wasn't fatal and he could have recovered quickly.
At the peak of his power, he had killed a Celestial in a single attack, and a single Celestial could create, destroy, remake, unite, and split universes with ease. In addition, they would be superior to Splendid Ap, who had created several universes both by accident and on purpose. But this is Typhojem, who is immensely enhanced by the Gems of Fury. So this shouldn't be used unless I want Gems of Fury Typhojem in the fight, but I'm just using Typhojem without any items he could use to buff himself.
In terms of speed, he should be far ahead of any Force user who can react in hyperspace, and hyperspace is known to have infinite speed. In fact, he is far ahead of FOTJ Abeloth, whose avatars can easily fight with beings in a state of oneness, and oneness allows the user to be one with the Force. Oneness should give someone a kind of omnipresence, to say the least.
As far as abilities go, he can overcome someone's mental defenses. Considering he's above FOTJ Abeloth, who's above DE Sidious. As such, Typhojem would have extremely powerful telepathic abilities at his disposal. As mentioned, he can resist existence erasure. He can project a portion of his presence. In all honesty, you can think of any ability that a Jedi or a Sith has, and he would be way, way above it. Soul hax, precog, energy absorption, etc.
So with all of that said, how far does Typhojem go?
Also, there's a bonus round with Nakhash replacing Typhojem. In short, Nakhash is so powerful that not even all the Celestials could stop him. The best they could do was flee from him and seal him.
