Forms

 * Default Form (Eisenmeteor): Spear that splits into 4 jagged ends that curve inwards, resembling a jaw. It can give off a small timed explosion or binds her enemies' hands. (Unnamed)


 * Velocity Spear, Silfarion (音速の鎗 シルファリオン Onsoku no Yari, Shirufarion): Spear with a triangular, arrowhead-like spearhead that increases Knightwalker's speed dramatically, however it's speed was matched by Scarlet's Flight Armor. Spear also improves jumping power of user.


 * Vacuum Spear, Mel Force (真空の鎗 メル・フォース Shinkū no Yari, Merufōsu): Spear with a wide spearhead with the endges on the side curving inwards close to where the spearhead is mounted, and a glowing orb connects to the shaft. It enables Knightwalker to perform a vaccum wave against the enemy.


 * Explosion Spear, Explosion (爆発の鎗 エクスプロージョン Bakuhatsu no Yari, Ekusupurōjon): Spear that creates explosion around the point that the spear hits, Scarlet, however, used the Flame Empress Armor to decrease the damage. Explosion does not damage to Knightwalker.


 * Gravity Spear, Gravity Core (重力の鎗 グラビティ・コア Jūryoku no Yari, Gurabitikoa): Spear that unleashes an orb of strong gravity. Used to stop Scarlet's Heaven's Wheel Armor attack.

 * Saint Spear, Ravelt (聖鎗 レイヴェルト Kiyoshi Yari, Reivu~eruto): The strongest form of the Ten Commandments. The spear head has the same shape as Ravelt in Rave Master, albeit shorter. It is made by the best blacksmith in Edoras, and its power is strong enough to shake the world with a single hit but destroyed by Scarlet's Fairy Armadura attack.


 * Cannon-Spear Form (Million Suns) : A form of her spear that seems to be able to blast shots of energy that can pierce through objects and foes. The name and full ability of this form have not been revealed yet. (Unnamed)

Trivia

 * In addition to sharing the same name, Erza Knightwalker's weapon also uses the same abilities as the Hiro Mashima's previous work, the Ten Commandments. However, instead of using a sword, she uses a spear, and the kanji sword (剣) is replaced by spear (鎗) for it's abilities.
 * All names and powers identical to Rave Master's Rave Ten Commandments although whether or not it possesses the remaining forms (Eisenmeteor, Million Suns and Sacrifar) is unknown at this point.
