Apocalips

Apocalips is an android that used to guard Juperos long ago. It was created by the ancient civilization of Juperos before the whole city collapsed to the ground. Like most androids and robots Apocalips, too, survived the collapse. They were built to withstand any kind of damage and to last for a long time. Unfortunately none of the citizens of Juperos survived; all perish during the collapse. Its artificial intelligence has corrupted over the years and can no longer distinguish comrades from enemies. Sadly, the android is nothing but a mindless monster now.

NOTE: This monster is also known as Apocalipse or Apocalypse in other versions of Ragnarok Online.
