Darkseid, the Lord of Apokolips and Thanos, the Mad Titan, are unquestionably two of the most fearsome villains their respective universes have to offer. Created in 1970 by the King of Comics himself, Jack Kirby, Darkseid has gone on to make a name for himself as one of the most powerful entities in the DC Universe. Since making his cameo debut in "Superman's Pal Jimmy Olsen" #134, Darkseid has arguably become the greatest enemy Superman, and even the entire Justice League, have ever known. Ruthless, calculating and fearless, Darkseid will stop at nothing to see the universe bow to his will.

Ever since his debut in 1973's "Iron Man" #55 by writer Mike Friedrich and writer-artist Jim Starlin, Thanos has been a plague on Earth's Mightiest Heroes and Marvel cosmic at large. A warrior literally willing to raise an army and massacre his own people to prove his love for the personification of Death, Thanos has been the wielder of the universe altering power of both the Cosmic Cube and the Infinity Gauntlet. These two tyrannical dictators are both obsessed with death, destruction and power, so it should come as no surprise that they have a lot in common, but can you tell who said what?
