Zero Sluggers

The Zero Sluggers (ゼロスラッガー) are double Crest Weapons similar to Ultraseven's Eye Slugger that are wielded by Ultraman Zero, Darklops Zero, and Ultraman Belial (as Zero Darkness). They can be used in combat and fire beams.

Name
Their name comes from Zero's name and his father, Ultraseven's, iconic crest blade, the Eye Slugger. The word Eye was instead switched for Zero.

Usage
Like the Eye Slugger, and all crest weapons in general, the Zero Sluggers can be used as projectiles, or as hand-held blades. Like all Crest Weapons, they can cut through dense materials. Energy can be directed into them to improve their cutting ability.

Unlike his father, Zero can use his blades to fire an Ultra Beam.

Thanks to his empowerment and various forms, Zero can use them for other means. This includes combining them into one larger crescent blade, known as the Zero Twin Sword (ゼロツインソード) and multiplying them and controlling them mentally. As Ultraman Zero Beyond, he has 4 of these Crest Weapons, however they are non-detachable and energy projections take their place when used in combat.

Zero Slugger Gear
In 2010, Tsuburaya Prod. and Televi-Kun launched a competition called New Power-up Armor Design Contest (新強化アーマーデザインコンテスト) for the readers to design armed forms of Ultraman Zero, where he would turn his Zero Sluggers into battle armor.

After the competition was over, the two winning entries made their appearance in Ultraman Festival 2010, as Zero splits into three and the two copies initiate the Zero Slugger Gear (ゼロスラッガーギア).

Two armors had been identified, namely Super Form (スーパーフォーム) and Keeper Form (キーパーフォーム) respectively.

Normal

 * Zero Slugger Attack (ゼロスラッガーアタック): A slashing attack with the Zero Sluggers.
 * Zero Twin Sword (ゼロツインソード): The Zero Sluggers turn into a crescent-shaped blade using the Plasma Spark's energy.
 * Plasma Spark Slash (プラズマスパークスラッシュ): A slashing attack with the energized Zero Twin Sword.
 * Combination Zero (コンビネーションゼロ): A combination attack with Ultraseven using both the Eye Slugger and the Zero Sluggers. The bladed projectiles circle around each then cut apart an enemy.
 * Reflection (Name Unknown): Naturally resembling the Eye Slugger, the Zero Sluggers are capable of acting as mirror-like substances, which he used in a strategized attack against Virainias and his Tyrant.

LunaMiracle Zero

 * Miracle Zero Slugger (ミラクルゼロスラッガー): Zero can generate three pairs or more of his Zero Sluggers, controlling them all mentally. He can bring them together in an attack similar to Combination Zero.

Zero Darkness

 * Dark Zero Ripper: An unnamed technique that was used on Glen Fire, it uses the Dark Zero Sluggers. He slashes the opponent in a blink of an eye, tearing through their flesh.
 * Dark Zero Twin Shoot: A dark version of Zero's Zero Twin Shoot.

Zero Beyond

 * Quattro Slugger (クアトロスラッガー): Zero creates projections of the 4 non-detachable Crest Weapons on his head and launches them at his target(s).
 * Beyond Twin Edge (ビヨンドツインソエッジ): Zero can wield two Zero Twin Swords made purely of energy, at once. They are also somewhat capable of ranged attaack by launching energy slashes.

Variations

 * Darklops Zero Sluggers (ダークロプスゼロスラッガー): A variation used by Darklops Zero. They lack the Zero Twin Sword form due to their robotic nature.
 * Darklops Sluggers (ダークロプススラッガー): Variations used by the Darklops. The models are no different to the ones used by their prototype, Darklops Zero.
 * Orb Sluggers (オーブスラッガー): A pair of Crest Weapons used by Ultraman Orb Hurricane Slash or Emerium Slugger, both of which tapped into the power of Ultraman Zero. These weapons visually resembles the Zero Sluggers in a light blue hue and are created by tapping into Zero's power. Unlike more conventional Crest Weapons, the Orb Sluggers are permanently attached to Orb's head and when in use, only energy projections are released.

Trivia

 * They were originally called the Double ISluggers (Pronounced Eye Sluggers), during Zero's development phase, when he was called Ultraseven AX and was all red, until it was changed as it made Zero more like another revamp of his father Ultraseven.
 * In Ultraman Geed, Darkclops Zero had fired his Darkclops Zero Shot while holding the Darkclops Zero Sluggers. Prior to wielding Darkclops Zero Sluggers in his both hands, blue projections is seen while being summoned from his hand similar to that of Orb Sluggers.
