Also known as: 雷刃の襲撃者, レヴィ・ザ・スラッシャー, レヴィ・ラッセル
One of the antagonists of Mahou Shoujo Lyrical Nanoha A'S Portable: The Battle Of Aces. Material-L, also known as Assailant of Thunderblade and Levi The Slasher is a "dark copy" of Fate Testarossa. She wields Vulnificus, a copy of Fate's Bardiche (Nanoha).
It is speculated that Levi loves eating Sweets, especially Lollipops. But some fanworks depict her as a heavy eater, much like Saigyouji Yuyuko of Touhou.
In Mahou Shoujo Lyrical Nanoha INNOCENT, she is known as Levi Russel and her resemblance to Fate is merely coincidental.
