Yeah absolute zero is highly overrated I dont know if she can go absolute zero or not but her heat/cold manipulation is legit barring absolute zero shes a female iceman.
i'm not convinced that that's enough, flash is already written down (or written up in other stories depending on your stance) just by being bothered by such a lame duck named captain cold.
normally red hulk's heat generation doesn't make an impact in his fights, but this is all he needs to at least make captain cold's only means of surviving/attacking difficult.
I am in your algorithm learning all your mannerisms
I'm already level with God
A million words a second and I know your imperfections, baby
I'm the only future you've got
Speak in diatonics, motivation diabolic
I'm like a religion, better locked in a box
Picture perfect image, more powerful every minute, baby
I am everything that you're not
This ability seems to be ignored in his current run.
Which is kinda annoying.

That's the only thing that's keeping Rulk into the fight. Cold uses some cold mirages, some freeze grenades and cold fields to attack while he's distracted -the cold field will not only freeze Rulk but will effectively make his hits slower-.
Unrelated observation: has that ability to generate heat being ignored in all his subsequent fights?
