Thanos & Darkseid at a GlanceEdit
Darkseid: Darkseid is an evil ruler of the fiery planet, Apokolips. He is an extradimensional being apart of the self proclaimed new gods who draw their power from another dimension. He has superhuman abilities and control over the Omega Effect, which 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 onto the target's soul, preventing it from escaping. Wonder Woman's bracelets, along with Superman and Doomsday, are some of 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 DC Universe. Apokolips and the New Gods live across the DC Multiverse. Darkseid also has a whole army of other New Gods with the same attributes as his, (except for the Omega Beams) that he can call on for assistance.
Thanos: In the Marvel universe, Thanos is a ruthless alien dictator from the moon Titan, who possesses many super powers and abilities, like a superhuman regeneration factor, teleportation, matter manipulation, and energy manipulation. He was formerly immortal because of Death's ban from her embrace, but this has been lifted.
If Darkseid and Thanos were in the DC universe/dimension, Darkseid could win if he used the anti life equation but in a one on one with no power ups besides natural powers Thanos wins, because he has a vast power difference to Darkseid. While his beams are very powerful, Thanos has a huge variety of powers without the Infinity Gauntlet, the blows from his punches alone can destroy planets, he's so strong he was on par and even overpowered an enraged Thor who has unlimited strength wielding the Power Stone which increases strength and power tenfold, where as Darkseid’s strength only sometimes rivals Superman’s, plus on top Thanos is one of the smartest beings in the universe, his matter manipulation is capable of downing someone like Silver Surfer and several other heroes.
Thanos is the most powerful super villain in the Marvel universe. Darkseid, is the most powerful in the DC universe. I'll let you take the decision, BUT, I'd still say firmly that Thanos could win. Thanos has super natural and magical powers and super human strength and can take down the Avengers and Justice League (only if it were in their dimension.) Thanos is much stronger and more powerful when he's at the universe which is the most favourable for the Infinity Gauntlet. Get on with it guys. Thanos could win, but it's up to you.
Who’d Win: Thanos
Make Your ChoiceEdit
Thanos’ main inborn ability is to absorb cosmic energy and use it to strengthen himself, both durability wise, power wise, etc, if Darkseid used his omega beams on Thanos he'd just absorb it and make himself unstoppable and completely destroy Darkseid, plus he is strong but his strength is only sometimes comparable to Superman’s, where as Thanos is immeasurable. But every time you see Darkseid, you see an avatar of him that is far weaker than his true self; meaning that he never actually left Apokolips and could destroy the Justice League.
So, Thanos and Darkseid are pretty close in strength.
