In addition to these tools, Roger has exhibited extraordinary physical conditioning throughout the series, and has been shown many times to be much more physically capable than most humans. Of particular note is his strength; he has been able to carry Dorothy on several occasions, once even holding her while jumping down around 15 feet, while it has been shown that any other character in the series who has attempted to so much as move her can hardly even budge her. Also, during his brief hand-to-hand fight with Alan Gabriel (who has been shown to have superhuman capabilities), he was able to not only hold his own, but floor the cyborg during their initial exchange. This level of physical ability is never explained, but the final episode of the show suggests, in one of several flashbacks that are themselves never explained, that Roger is himself an android not unlike Dorothy, designed for the purpose of piloting Big O.
