Undead RVD's "Super Ninja" Edges:
Melee: Both are very sharp and very deadly. One thing that gives the Digistruct Blade the advantage, is that it is a Digistruct weapon, meaning that if its blade were to be destroyed, the blade can easily be reconstructed. Kai's Monomolecular sword is quite deadly but is also quite breakable and, worse yet, CAN'T be reconstructed at the spot. Range: The Elemental Kunai have a far greater level of variety and versatility over the hardly-used Palm Blaster. As such, the Kunai feel to be the more effective tool. Speecial: Between the two, I give it to Decepti0n. Unlike Tactical Cloak, Decepti0n is more than invisibility but also... well, deception. It creates a hologram of himself that is lifelike an almost every way and can fool even keen-sensed enemies. Tactical Cloak is quite useful but Kai has too much pride to use it effectively, using it rather to escape like a pussy than to eliminate his foe.

Overall:
Kai is only deadly to enemies who are at a disadvantage (e.g. are untrained, are terminally ill). Take away any advantage and he will go down hard. Zer0 is deadly to enemies who have an advantage (e.g. far greater in numbers, far larger and tougher). It is also unfair to say that Zer0 is not as adapt with his sword as he is with a Sniper Rifle; personally, I think he is BETTER with the sword than Kai, who utilizes much more basic techniques. The real way I see it going down is that Zer0 activates his Decept0n, which will not only deceive and distract Kai but will also allow him to insta-kill the Cerberus assassin with a sword through the back.

VOTE: ZER0
