Monolith

Monolith (石頭) is one of Lexaeus's weapons in Kingdom Hearts 358/2 Days. It is a moai.

It is also notable that since the description for "Mystery Gear" states that it brings out the user's personality, this may be a reference to the fact Lexeaus tends to be "stone-faced".

Design
The Monolith is seemingly made entirely out of grey rock. Its “blade” takes the form of a moai in profile, while its counterweight is a flat section of rock that juts out from the back of the moai’s head.
