In issue #200 of Archie, the Egg finally cracked. Eggman went insane after Sonic destroyed his Egg Tarantula. He started to go insane from his many failures and the "betrayal" and death of "his children". Look at Archie Eggman's page on this wiki or Mobius Encyclopeadia to get a better understanding.
