  == Secret Wars II ==  I seem to remember the following story being part of the secret wars II storyline, but my memory could be at fault. I think it deserves a mention in either the Mephisto or Beyonder sections. The following is from http://www.marvunapp.com/Appendix4/beyondersw.htm  (Amazing Spider-Man I#274) - As the Beyonder stood in space, he was attacked by a preemptive space fleet of aliens bent on destroying him. He wiped the fleet from existence, then did the same to the homeworlds the members of the flee emanated from. Realizing that certain cosmic powers still retained the memories of those beings, the Beyonder set out to wipe out those too, starting with Mephisto. Mephisto offered a wager to the Beyonder: Should Mephisto's champion win their duel, Mephisto's realm would be allowed to remain after the Beyonder wiped out the multiverse for a full day. The Beyonder chose Spider-Man to be Mephisto's champion, then chose the demon Zarathos as his own. Zarathos tried to corrupt Spider-Man by taking the forms of various people who had died in Spider-Man's life, but Spider-Man overcame the psychological torture and defeated the demon. The Beyonder allowed Mephisto's realm and the multiverse itself one more day of existence.
