Suggested by Destroyer Now this is a really close battle between two of Marvel’s top heavy hitters. Both of these characters can easily end the planet in an instant. I would say that Thanos has more hax with the Gauntlet while Jean Grey definitely has the better long range options. In a fist fight Thanos is winning this one but he’ll have a hard time keeping up with Jean Grey in the air. So it can go either way but ultimately I trust Thanos more with his tactics and more attack options. Thanos wins.
