Zero Sluggers

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

Name
Their name comes from Zero and his father's iconic crest blade, the Eye Slugger. However the 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 directed into them directly 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 and multiplying them and controlling them mentally.

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 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.

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.
