Jumbor Barutronica (Japanese: 重機人間ユンボル, Hepburn: Jūki Ningen Yunboru) is a Japanese manga series written and illustrated by Hiroyuki Takei. It was serialized by Shueisha's shōnen manga magazine Weekly Shōnen Jump from December 2006 to March 2007, with its chapters collected in a single tankōbon volume. Two one-shot chapters were published in Shueisha's seinen manga magazine Ultra Jump in October 2009 and February 2010, and after that, Takei relaunched the series under the title Jumbor in the same magazine in July 2010; the series has been on indefinite hiatus since 2015.
