Woodney is a character with a few extra pounds who attempts to imitate Train by dressing in black, referring to himself as the "Black Cat" and having a "thirteen" tattoo (albeit in Arabic numerals, drawn and erased everyday though not always on the same arm) He meets with moderate success as a sweeper by using the Black Cat's reputation to intimidate his enemies, but this tactic can backfire when he is faced with powerful criminals. After an encounter with the real Train, he gives up imitating him and attempts to become his disciple, but Train convinces him he would help more by being an informer to them. In the Anime, the only main difference in Woodney is that he keeps on following the group, instead of turning into an information broker, and is the cause of some humorous moments. Unlike in the manga, Woodney caught on faster to realize that Train is Black Cat. He appears to have a crush on Silphy in their first meeting.
