Kobayashi Shinji (小林 信治) is a sanitary engineer who attempted Sasuke 10 times. Four of his attempts were cut from the broadcast.
His first appearance was in SASUKE 11 after he qualified for the tournament by placing third in the Monkey Bars event in Taiku Ookoku. In the tournament, he performed well, clearing the First Stage with ease. In the Second Stage, he set a time record which stood for several years until it was broken by Nagasaki Shunsuke in SASUKE 18. In the Third Stage, he made it all the way to the Pipe Slider, but could not keep the bar at the end of the track and his grip eventually gave way.
In his next two appearances, he failed to clear the First Stage. His SASUKE 12 performance was all cut and in SASUKE 13, he was digested. It is shown that he mis-hit the trampoline and could not grab any of the ropes on the re-designed Jump Hang.
In SASUKE 14, he blazed through the First Stage, clearing the new Ensuitobi quickly and pressing the red button at the end of the stage with his foot. He continued on through the Second Stage and cleared. He was the first to attempt the re-designed Third Stage. He glided through most of the obstacles and successfully cleared the new Jumping Bars and Climbing Bars. When he got to the new Devil Balanço, he was able to build enough momentum to grab the Pipe Slider, however when he attempted to grab it, he missed and the bar moved much further away from its starting position. He continued to swing, but the distance was far too great and he fell there. He was the only person in that tournament to beat the Jumping Bars and Climbing Bars.
He returned for SASUKE 15, wearing #98. There, he made it through most of the First Stage. However, on the Neshireta Kabe, he tripped on the small railing and made a desperate attempt to grab the rope, but failed. In SASUKE 16, he cleared the First Stage. However, he, like many that day, failed the Metal Spin, which had been altered since he beat it in SASUKE 14. He did not compete in SASUKE 17.
In the Shin-SASUKE era, he has competed four times, three of which have been cut. His performance has been lackluster as he hasn't cleared the First Stage. His only shown appearance was during SASUKE 20, where he failed the Jumping Spider. Before Shin-SASUKE, he was treated like a SASUKE All-Star, complete with theme song, In fact, Kobayashi was mistakenly called an All-Star on some G4 broadcasts. After SASUKE 21, he retired from SASUKE and no longer competed. He has failed the First Stage 7 times, the Second Stage once, the Third Stage twice and he has never made it to the Final Stage.
