In one of his quests to defeat Thor, Loki learns about an ancient artifact of Mephisto, brought to him by one of the agents of one The Demons Lords. Loki goes after this artifact and after months of searching finally finds the Lexicon. With little trouble, he solves it and Pinehead shows behind the walls to get him. Loki asks who is him, and he answers:
"I'm Pain. And i came to penalize you."
Loki then says he isn't going to hell without fighting. Who wins?
