History
Wade Wilson resorted to dealing with Mephisto while trying to get revenge on the Wade Wilson of Earth-616, who had overthrown him from his criminal empire. Wilson offered his soul to Mephisto in exchange for opening a gate to Hell and letting the Infernal Hulk return Earth, but the demon tricked Wilson and made him go to the torture pens before going to the arena of tainted souls, stating that he would release Wilson in a few decades or centuries maybe.[1][2]
