A character of mine is able to heat himself up to extreme temperatures (with required secondary powers to both survive and avoid completely destroy everything in a certain radius around him). I also heard different materials have their conductivity changed based on temperature.
What would be the effects of repeated lightning strikes if
a) He can only heat himself up to fractions of said lightning strikes
b) He can match the temperature and/or surpass the lightnings' temperature
c) He is immune to heat-based damage no matter how high
The reason I am asking is if heating the human body somehow increases conductivity, the current from the strike will just flow through the person and pass harmlessly through.
Edit: If the air around him heats the plasma and one of the required secondary powers involve him moving oxygen to himself to breathe, will the above question be meaningless since plasma conducts electricity well.
