Hayate Gekkō

was the examiner of the preliminary round portion of the Chunin Exams.

Part I
At first sight, Hayate appeared to be not in the best of health, as he had an unexplained chronic cough and bags under his eyes. He is scheduled to be the proctor during the final rounds of the Chunin Exams, and so oversees the preliminary matches that will decide who advances to the finals. After the preliminaries are completed and the participants are given a chance to train and recuperate, Hayate learns of Sunagakure and Otogakure's plans to invade Konoha by eavesdropping on Baki and Kabuto. Before he can tell the Third Hokage what he has learned, he is killed by Baki. Genma Shiranui replaces Hayate as proctor for the finals.

Abilities
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. He also possesses great speed, as he demonstrated during the Chunin Exams when stopping Neji from attacking Hinata.
