Malicious is a biological super-weapon created to bring peace but instead was used for evil. No Government, or Alien Race can create such a powerful weapon and not have it under their control. That's the very reason Malicious has a weakness; Human Blood! They've made him so that if he doesn't get coded Albumin every few hours from a Human source he is basically going to go Supernova and end life itself, something which he has sworn to protect. His Myriaxium Core, which is his beating heart of a dead star, is designed to release all of its energy upon his reluctance to take Human lives.
