What is the name of anime show that was shown late at night on toonami and had a cat women chasing some one in episode she bath lava?

You're likely thinking of "Black Cat".

Here's why:

* Cat Woman: The protagonist, Train Heartnet, has a partner named Eve who is a skilled assassin and has cat-like abilities. She's often portrayed as having cat-like features, and even wears a cat-themed costume in the anime.

* Lava Bath: There is a scene where Eve is submerged in a pool of lava-like substance, which she is able to survive due to her enhanced abilities.

This scene, while not exactly a "bath," is a memorable one where Eve's unique abilities and resilience are highlighted.
