Character DetailsEdit

Physical DescriptionEdit

Lord Sam Sinister is mostly seen wearing a tan hunting jacket (later replaced by a black version with a white scarf), dark gray pants, and a white pith helmet, which was later swapped out for a top hat. He has an angry expression on his face with a red scar on his left cheek. He has a monocle over his right eye and a thin, curly mustache above his mouth. He has a goatee on his chin. His left hand is missing, with a hook in its place.


Lord Sinister is a very abrasive, cunning, aggressive, and intelligent villain. Highly selfish, he is willing to do nearly anything he can to get what he wants for his private collection, even if it means killing one of his own men. He usually becomes frustrated over his henchmen, such as Patrick, but still proves to be a worthy enemy to Johnny Thunder.
