Thanos and Darkseid are two similar and very powerful characters. I believe that if they were ever to face each other then the results (as well as the battle itself) would nearly destroy all the universe around them. If they were ever to face each other, who'd win? Let's find out!
Thanos & Darkseid At a GlanceEdit
Darkseid: Darkseid is an evil ruler of his own fiery planet; Apokolips. He is a god with superhuman abilities as well as control over the Omega Effect. This allows him to project eye beams that can not only incinerate or teleport but can also turn at right angles to catch their opponent. The Omega Beams,sometimes called Omega Sanction, lock on to the target's soul and therefore the target can't escape. Wonder Woman's bracelets, Superman and Doomsday are some of (if not absolutely) the only things to withstand a blast of his Omega Beams. Darkseid has a large set of other powers that make him nearly omnipotent. Darkseid is said to be hundreds of thousands of Earth years old though Apokolips lives outside the normal boundaries of time and space in the Universe. Apokolips and the New Gods live across the whole multiverse with only the single form they always have. Darkseid also has a whole army of other New Gods with the same attributes as Darkseid, barring the Omega Beams, that he can call on for assistance.
Thanos: Thanos is a ruthless dominator from a planet he has instilled great fear in and devastated. He is a titan that possesses many super powers and amazing abilities. Thanos's power is best shown through his encounters with others (a point that shall be addressed later on). He possesses powers like a superhuman regeneration factor and teleportation, matter manipulation and energy manipulation. He was formerly immortal because of Death's ban from her embrace but this has been lifted since then. He has wielded the Infinity Gauntlet before and eradicated half of all life in the main Marvel Universe with it, yet the Gauntlet is powerless outside of its home dimension.
Thanos kills Darkseid with one punch, though darkseid also has the anti-life equation, therefore this still means a mystery.
