Black Knight (FE) vs Nightmare (SC)

The evil knights from Fire Emblem and Soul Calibur duke it out.

Black Knight from Fire Emblem has Alondite, Imbue, and Eclipse, no blessed armor and no Nihil (ie: RD incarnation)
Nightmare from Soul Calibur has Soul Edge and is separated from Siegfried (ie: SC3 or SC4 incarnation).

If Eclipse activates, Nightmare is allowed to transform into Night Terror.

Nightmare, pretty easily too.

Nightmare wins and without going Night Terror.

Is anyone going to vouch for Black Knight, or do I have to play devil's advocate and put a few words of support in for Black Knight?

I’ll vouch for Black Knight since no one has done so.

The Black Knight was able to fend off the entire Laguz Army by defeating Skimir
He fought Tibarn, the king of hawks, to a draw. Tibarn is one of the most powerfulest units in FE, he has enough speed to double strike Ashera and Black Knight himself, yet BK fought him to a draw.
Black Knight can also teleport to distant locations, he teleported right in front of an attack to save Micaiah.
Black Knight also has the eclipse ability, which basically allows him to defeat any opponent in Fire Emblem, even Ashera (if she didn’t have mantle), if it activates. This ability negates his opponent’s defense and quintiles his strength, which equals instant kill with any weapon. Its activation rate is based off his skill, which is 40%. Thus Black Knight has a 40% chance to win every swordfight.
