True Berserker's True Name is unknown.
Berserker appears as a robot with spider-like legs and a lion motif.
While his identity remains unknown, it is known that his Noble Phantasm has enough power to impede True Caster's and Francesca's magic, disrupt Saber's Excalibur, and he possesses the natural opposite to True Assassin's Shadow Lantern Skill, due to having invented the lightbulb.
