Er how about Magneto ripping a train in half in X1, or Rogue absorbing Wolverine's powers so the stab wound he just gave her healed not killing either of them or an unconscious Rouge subconsciously absorbing Wolverine's powers so all of his injuries come back. Or Nightcrawler taking out the White House staff with ease using teleportation, or Magneto breaking out of prison by forming small metal balls out iron injected into a guards blood, or Storm using a field of Tornado's to shake off two fighter jets, or Mystique infiltrating Styker's base by imitation Wolverine then Stryker, or Jean using her powers to simultaneously stop a wall of water and lift the X-jet, or Superman saving the plane, the bullett to the eye scene, or using heat vision to melt debri that is falling onto innocent people or Superman travelling above the clouds to be bathed in sunlight when in a weakened state.
PLEASE, one thing people cannot claim of Singer is that he doesnt use imaginative ways to display powers.
