he also got hurt by superboy's heat vision too, point is it still boils down to the fact that once supes body recognizes an injury its gonna react. bobby would be fine in his system as vapor or water as long as he doesnt try anything but the moment just ONE molecule is ruptured(believe i said that before) his body is gonna combat that adverse reaction, like i also said before when reg. humans get injured our bodies react immediately as well but on a microscopic scale, supes body reacts on a macroscopic scale, or whatever terminology exists for something bigger and faster than macroscopic.😆
so as a result the only feasible way i look at this is if bobby can drain him faster than he can heal, which i doubt, in freaking sunlight no less. a couple pages back i showed supes being drained by a huge nuclear bomb. and he was restored after he drained solar energy from plants and trees, and that was in the abscense of sunlight.
point is contrary to popular belief if you drain someone of all thier moisture thier not gonna disintigrate into ash, but rather they'll look just like bodies that have been mummified for hundreds of years, or when they find frozen bodys in the arctic or something,(or like the pic i posted a few pages back) so as soon as bobby leaves his system he would regenrate all those damaged cells instantly, so again... we're talking about a temporary incovenience. but the thing is this battle would be so fast paced that i doubt he would get the chance to do that anyway, besides he would have had to do that after he was smashed to bits by supes anyway. so if we're judging this battle by who can incapacitate who first its obviously superman, but i think we all can agree that neither could kill each other.
