@UltimateHero0406: The second video is stylish, though the first is outside the game canon. I'm not saying that Sonic and Shadow do not have some measure of durability and strength, it just is nowhere near X and Zero's level and not close enough to make a difference here. Heck, by feats, Mega Man and Bass outclass Sonic and Shadow in durability, firepower, and strength (surviving 12,000 degree C heat, temps near Absolute Zero, lifting giant robots and fortresses, and so forth).
One of the reasons Sonic can dodge Eggman's robots and his projectiles is because they do not have sufficient speed and reaction time to track him. X and Zero do not share this problem. I've outlined their speed and reflexes and the supersonic threats they've conquered earlier in the thread and will do so again if necessary. Sonic is not going to be able to evade threats that can react and target him at his level of speed. That's a problem, because speed is the source of his primary defense and offense.
Not to mention one of X's base forms is capable of launching hails of large plasma blasts that track their targets regardless of evasion and strike with 100% accuracy (Mega Man X:Command Mission).
