メカ沢新一
One of the more famous delinquents in [[Sakigake!! Cromartie Koukou]]. Voiced by [[Wakamoto Norio]] and Jay Hickman.

Is notoriously bad with machines... 

[spoiler]...despite the fact that he himself is one, and everyone but the main characters do not seem to notice this.

Also, he later acquires upgrades that allow him to transform into a motorcycle.[/spoiler]
