Hayate Gekkou was the examiner of the preliminary third portion of the Chuunin exams. The name “Gekkou” means “moonlight” and “Hayate” means “quick as wind” or “hurricane”.

Little is known about Hayate’s abilities, except for a move which he used on Baki that failed. This technique is called Dance of the Crescent Moon, which is an advanced technique that creates multiple clones of the user while the real person attacks from a blind spot from above. Baki comments that the village has talented ninja, seeing Hayate can use this technique and has mastered it at such a young age. From this we also know that he owns a katana, and possesses great speed, as he demonstrated during the Chuunin Exams when stopping Neji from attacking Hinata.
