Warehouse Agent - Undead. Dark, 3-star.

Zombie, 1200 ATK/900 DEF

Old Bone is the Guardian of the Origin Circle, which holds some of the world's most well-known artifacts - such as Thor's gear.

Thor's Gear Spell equip. This artifact can only be equipped to a Warehouse Agent. The Agent then gains 1000 ATK. The Undead Agent, if on the field, will gain 1000 DEF

(This is because OB was created to protect Thor's stuff.)
