Thanos:
Has the infinity gauntlet, which gives him total control over all of reality.
Immortality
Invulnerability to even adamantium, the strongest substance on earth.
Super strength.
Darkseid:
Omega beams: just insanely powerful and injure you to the brink of death, and don't stop until they hit their target.
Immortality.

Edited by TheCaptainM91: 5/16/2015 8:11:05 AMEveryone here knows about the Infinity Gauntlet and Thanos... then Darkseid would have the Anti-Life Equation, which allows him to dominate the will of any sentient race, among other reality altering powers that twist and distort freedom. That, or Soulfire Darkseid.
