Who is this character and who's outfit is he wearing? سہارا for who can answer it right~

It's Excalibur from Soul Eater wearing Mephisto Pheles' outfit from Blue Exorcist

Well, I know that the character is Excalibur (FOOL!), but I'm not sure who's outfit he's wearing. I mean, It looks deathly similar to his own, but, I mean it's different. IDK.

Excalibur

Excalibur from Soul Eater
