Loki vs Khan
Loki and Khan(reboot version) face off in the zombie-infested land of World War Z. Khan has the bigass minigun style phaser he used against the Klingons in Into the Darkness. Loki has his spectre, but isn't allowed to use any of its more exotic abilities like mind control, illusion casting etc.
Battle is to the death. Whoever loses gets resurrected in the real world and has to sleep with the main character of "My 600 lb life".
With the above mentioned motivator, who wins?
