Grand Finale! Samus vs Raziel

Well, the whole Screw Attack could possibly be negated by Raziel's TK abilities. Remember, enemies are more susceptible to TK when they're already airborne. If she tries to stay in Screw Attack, all he has to do is pull her back down towards him.

On top of that, I have a genuine concern as to whether or not Samus' Power Armor would absorb the damage from Raziel's Wraith Blade at all. Her ability to take damage is not based on the strength of the metal, but on the strength of her energy shields that surround the armor. When her shields run out of power, she's dead. The actual metallic composition of the armor can't withstand attacks after the shields dissipate. With that said, Raziel has shown the ability to attack through energy-based barriers in both Soul Reaver 2 and Defiance, and as such, the wraith blade might be capable of cutting through her shields.

But, then again, that's entirely speculative, and only based on a few examples from the games. Either way, it's a possible flaw in Samus' defenses.
