Okay, so it has been established that people that can spontaneously combust can melt the chip. What about people that can survive being set on fire? Or people that could potentially melt/short/damage the chip with any other type of energy like/other than fire?

Karla here can absorb and redirect large amounts of energy. Her powers make it so that she can survive explosions, fires, and energy attacks (yet, for some reason, not bullets of knives).

Would she be able to short out the chip somehow by either overwhelming it with energy or somehow being set on fire? Or does it have to be a total molecular immolation to melt them?
