Amidst the chaos of the isolated singularity that was Fuyuki in Japan, the Holy Grail war was leading to the near destruction of the whole city as areas were in flaming rubble. Due to her recent defeat by the overpowering servant Saber, she lost utterly and the effects of the singularity caused Medusa to become corrupt and end up a rogue Alter servant of her former self, that being a Lancer-class. She was garbed in a tattered black cloak which only partially covered her strapless dark top and skirt combo, having a longer cloth on the front. She also wore dark gloves and partially armored boots. Her pale purple hair was as long as her own body which complimented her pale complexion

It's been some time now since her defeat and she took it upon herself to even go after innocent people as well as having just recently turned her own master into a stone statue. She stood with a sinister smirk in the center of her little "Garden" of petrified statues which were due to her Mystic Eyes as the fabled Medusa of myth, now a rogue servant willing to cut down or toy with unsuspecting people or creatures spawned from the Holy Grail. For the hell of it she even used her sleek chained scythe to behead a few of the statues which bled somehow. For that brief moment she was blissfully unaware of any other potential victims in the vicinity, being lost in her sadistic high as her hood covered her faintly glowing pale yellow eyes

"How delightful..not even those other servants were satisfying enough to fight."
