Round 2! Seymour vs. Sigma

Also, I am not too sure if the Mortibody can actually be there in the field without Seymour. (While Anima is out there fighting.)

Mortibody completely relies on Seymour, it would even drain life from Seymour when it is hurt significantly. Also, isn't Moribody just a flying machine? (For that reason, I doubt that it can act on its own. Or it will perform rather poorly without Seymour's aid.)

Anima itself won't put forth much of a threat to Sigma. Pain is ineffective to Sigma, and Sigma can just beat Anima in his normal (size) form. More agile, easier to avoid damage. Sigma has different weapons, Light Saber, Death Scythe, Laser Beam, Homing missiles, and he can fly. Do not forget that Valguader will also be around, breathing out deadly fire and ice...(Fire and Ice....reminds me of Chocobo Hot and Cold...).
