Stan is the enemy of Gooooooooooooooooood. It is a ✧✧✧✧✧ (Ultra Hard) difficulty boss. However, it can not effect you because he is at another cosmo-reality. But he is so powerful that he can trick your mind from that far.
Satan was a member of the Red Prime. God wanted that group to respect and take care of the first human. Every one except Satan did it. Satan said "You created me from fire. But you created him from soil. I am better than him." Then God downgraded Satan's power. Satan is so angry with the first human and his generations.
