How to make a character who can control fire and is immune to damage from it?

Eventually, you hit results on the radiation table where if you don't roll, you can't get a critical success and won't get better. Above 4000 rads you get worse even on succesful rolls.

I'll confess that while the table does add to the realism of radiation results, I don't much care for the additional complexity. It probably should've used the disease or poison mechanics.

It's more about what is conducting the heat than the exact temperature. You don't take damage from the blast of 450 degree air from opening your stove the way you would from getting hit by 212 degree water.

With humans, we generally take fatigue from making our core temperature move away from 98.6 too much or too fast or really from dehydration from our bodys' attempt to avoid that. We take damage when something causes our cells to burst usally from going above 160 degrees F or below 32 degrees F dependent on thermal conductivity.

I have no idea how you could make easy to use and remember rules that would come close to that level of accuracy.

Write invulnerable to fire on the character sheet, call it good.

I'm pretty sure that only works for you. Most everybody else probably would want a point cost or something.

I guess if someone wasn't willing to just "write it down and call it good", then they might be willing to pull Invulnerability to Fire from 3rd Ed, and use that as a point value. Arguably, whether you try to build invulnerability via Insubstantiality, Regen, high DR, high Cosmic IT:DR, or maybe others, the costs start converging towards similar values to those given in 3rd Ed (they're often somewhat more expensive, for inarguably less true invulnerability, but still). For the sake of argument.

Resistant (Heat) (Occasional) (Immune, *1) is the RAW method.

(GURPS Powers, pg 118 - 119) for how to calculate "Invulnerable to Fire".
DR 30 (Limited (Heat/Fire), -40%), usually. You can do the Insubstantiality build it suggests, and add Cosmic (Rules Exemption; Can Shield Others w/ Body), +50%, so that you can shield others behind you while not suffering the effects yourself if you want that functionality.

IIRC, Control allows for a certain amount of DR against the element you control (unless that's one of RPK's house rules.) I'd consider subtracting that amount from the DR you need to buy.

For standard Powers, its a Power Block Stunt [Powers.p168].
PK's House Rules (#4) makes it a normal effect, or doubled when used as a Stunt.
