The Black Primer is a Lexicon that can be wielded by Zexion in Kingdom Hearts 358/2 Days. It is the form the Lexicon takes when not equipped with any Gears.


The Black Primer is a rectangular lexicon. The top and bottom sides are concave and the spine of the book sports a white, hour glass-shaped symbol lining it. Both covers are dominated by a large, dark grey "X". These marks are rather uneven and blotched, and they are each surrounded by a grey border. All of the other visible spaces on the lexicon are black.

"Black" refers to the weapon's dark coloration. A primer is a textbook used to teach basic concepts. An encyclopedia is a reference material that covers a wide range of subjects.


Black Primer's normal ground combo consists of a slash straight down with the spine up, a sweep from Zexion's upper right to lower left and back, and a wide angled telepathic swing that serves as the finisher. The Y-Combo chain consists of a sweep from left to right, a wide slash upwards, and flinging the Black Primer forwards while spinning.

The aerial combo consists of two quick strikes on an angle, and spinning the Black Primer forwards for the finisher.
