Sarge is one of the more eccentric characters in the series, as most of his actions and ideas involve violence, even when it's illogical. Although far from being as detached from reality as Caboose, Sarge's constant military rambling, illogical solutions, and irrational tendencies have suggested that he is one of the less sane characters in the series.

Being a military man, Sarge is very determined, mostly to unreasonable levels, as he still persists to fight the Blues despite knowing the truth of both sides. Sarge is also incredibly adamant as he refuses advice from others while believing that he is right. However, Sarge has the ability to be a loyal and compassionate leader, as he explains all the positive traits of others with a bold speech in Rally Cap and Reckless and has come to rescue his troops and others from mortal danger as seen in Upon Further Review and True Colors.
