Mephisto vs Lex Luthor...
Mephisto is on the prowl for valuable souls and has now targeted Lex Luthor...
As is standard, Mephisto gets 1 month to learn all there is to know about Luthor (via living minions looking to gain favor with him, the souls of the dead in his possession, and by sending demonic spies to watch him) before striking...
Mephisto cannot harm/kill, use mind/emotion control, or take Luthors soul by force; he must convince Luthor to give it up freely and willingly (Mephisto is allowed to lie and use trickery like there is no tomorrow however)...
Can Mephisto get Luthor under these conditions?
Or is Luthor able to resist the Devils charms?
