Hyperthermia is elevated body temperature due to failed thermoregulation that occurs when a body produces or absorbs more heat than it dissipates. Extreme temperature elevation then becomes a medical emergency requiring immediate treatment to prevent disability or death.
Who is Doomsday, and why should we care about his fight against Superman, Batman, and Wonder Woman? The latest trailer for Batman v Superman: Dawn of Justice gave us our first look at the really big, really bad muscle for the film, the monster known as Doomsday. The character/creature has a long history with DC Comics and ties to a few very significant events, namely the death of Superman.
So, even if Batman is able to target superman with kryptonite, he can go for sun bath in an instance and he will return fresher than ever. In a real fight, even if Batman has worn a kryptonite suit; superman could grab him and throw him into the space. FIGHT over!!!. Common on, he was able to throw island made of kryptonite into the space!!! My pick: Superman although Batman has got great movies.
