LUFFY POWERS :
Luffy ate Devil fruit and became Elastic however he is Dumb, he Evolved some of his Powers and Never admits Defeats!
Luffy's only weakness is his Dumbness.
Reed is Elastic and Super Genius. He got his Power from Outer space Experiment.
Reed does not possess superhuman speed and strength, he is not a master of fighting. Reed tends to rely more on his intellect in a battle then his elasticity.
