This robot paper model is the Noisy Boy (The Steel Samurai or The Manga Mangler), a Japanese robot, created by Tak Mashido , who fought Rubicon for the WRB belt in 2016 and lost by luck, based on the American sci-fi sports drama film. The paper model is created by DreamWorks II Distribution Co., and there are simple and detailed two versions.
Noisy Boy had a WRB record of 15-1. His only WRB loss was to Rubicon in 2016 which was a close match up until the third round where Rubicon got lucky with an uppercut that knocked out Noisy Boy.
Later, he was sold to Charlie Kenton who took him to the Crash Palace to fight, and arrogantly decided to fight him against Midas , one of the strongest bots there, and lost with Noisy Boy losing an arm and his head. [Source: wikia]
