Several wizards are all transported to Pelennor Fields to see who the mightiest magician in the multiverse is. The contestants are:
Raistlin Majere (Dragonlance)
Rand al'Thor (Wheel of Time)
Elminster (Forgotten Realms)
Voldemort (Harry Potter)
Quick Ben (Malazan)
Allanon (Shannara)
All the wizards are in their mortal forms and not allowed to use god powers IE Raistlin is not in his god form and Rand can not manipulate the pattern.
Gender: Male Location: 1/9.7'rd Horseman of the Apocalypse
Raistlin is physically sickly and dying. That said he killed the entire pantheon of gods in his setting and caused an apocalypse. He found a way to make one mortal, killed her and stole her power, than straight up rocked the rest of the pantheon.
