Tell me this you guys... is a martian in DC weakened in the presence of fire or fire and/or heat? because having a weakness against fire can be dealt with.. its the heat that can be the problem. Because there are a lot of things that emit heat but not everything has to burst into flames. or am i being stupid and not realizing that you cant get one without the other?
the thing is if he has a weakness against heat than his eyes beams cant be heat vision either ( was always under the impression they were just beams of concussive force)
