The verdict: A coin flip, with Loki by a hair

Fight rules: both fighters at their peak, no preparation, no allies, only their own powers and personal gear. A win is a knockout, a restraint they can't escape, or a forced surrender. The percentages are fan estimates, not official information.

Doom's edge

A will that has broken mind control for decades, so Loki's illusions and charms find little to hold. Doom is also the stronger sorcerer, with armor and science on top, and Loki avoids fair fights; under this site's rules he gets no time to set a trap.

Loki's edge

Millennia of sorcery, illusions and shapeshifting, an Asgardian's strength and durability, and a schemer's habit of winning before the fight starts: his trick on the Hulk is how the Avengers came together (Avengers #1, 1963).

Odds against every version of Doom

Doom's chance of winning, version by version. The strongest Doom here, God Emperor Doom, wins >99% of the time; the weakest, Fox Doom (2005), wins 11%. The last column says what moves each version away from classic Doom's 42%.

Loki is the son of the Frost Giant king Laufey, raised in Asgard as Odin's son and Thor's brother (Journey into Mystery #85, 1962). His scheme to trick the Hulk brought the Avengers together (Avengers #1, 1963). He died in the Siege of Asgard (Siege, 2010), came back as a child (Journey into Mystery #622 to 645, 2011 to 2012) and remade himself as a god of stories (Loki: Agent of Asgard, 2014 to 2015). With Doom he has been a partner more often than an enemy: Loki recruited Doom for his council of master villains in Acts of Vengeance (1989 to 1990), though Doom sent a Doombot in his place, and both sat on Norman Osborn's Cabal during Dark Reign (2009).
