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.
He is a humanoid/ plant elemental creature, created by writer Len Wein and artist Berni Wrightson. Swamp Thing has had several humanoid or monster incarnations in various different storylines. He first appeared in House of Secrets #92 (July 1971) in a stand-alone horror story set in the early 20th century. The character then returned in a solo series, set in the contemporary world and in the general DC continuity.
