Couldn't they just make a suit for Touya/ Dabi?
I've been thinking about it a lot and i just can't help but wonder, if endeavour didn't fuck up as a father and actually tried to find a solution to Touya's quirk incompatibility couldn't there be a way to actually build a suit for Touya?
Since he was a kid and when he became dabi too we notice that his flames, despite his body, don't immediately melt him like they should, for example blue flames are incredibly hot and just using them in your first would literally melt it within seconds.
So I think he kinda had some kind of resistance, but simply his mother's ice resistance prevailed and left him with a flawed resistance that still hurted him.
But since we saw in his final battle that he did have the possibility to produce both ice and fire makes me believe that a suit could have worked.
Let me explain, so, we know he's resistant to ice, so the suit can pump sub-zero liquid coolant (like liquid nitrogen or a specialized chemical refrigerant) continuously against his skin without giving him hypothermia.
As Toya's core temperature spikes from fire production, the internal suit absorbs his body heat into the liquid before it can burn his skin or melt his outer tissue, stabilizing his temperature at a safe threshold.
I think the suit uses highly conductive internal wiring(made of materials like synthetic diamond or heat-conducting graphene) that runs from his core along his limbs to his extremities. That way Heat naturally flows from hot to cold. The conductive channels siphon the massive thermal energy generated by his organs and route it away from his vital center, driving the energy straight down his arms and legs to prevent localized internal cooking.
Then there's an ejection system that expels fire. The thermal energy routed from his core builds up inside some gauntlets. Once the pressure or heat reaches a critical limit, the vents mechanically open, blasting the built-up heat outward in focused, high-pressure streams of plasma or blue fire.
I think a suit like that genuinely works, and since at some point he could've unlocked ice the suit wouldn't be even needed anymore (maybe).
Let me know what y'all think
