The Iron-Masked Marauder is skilled at hand-to-hand combat but does not have good balance. His primary combat relies on Pokemon that are brainwashed by his Dark Balls. Once caught, The Pokemon are extremely loyal to him and attack without regards to previous friendships and loyalties. It is not known how he got them, but it is possible that he invented them.
The Iron-Masked Marauder is one of the first example of a most evil villain wholly without redeeming qualities within the Pokemon franchise- he was cruel, ruthless, cunning, selfish and generally uncaring of whomever he hurt. He was a outright depraved psychopath by nature, and willingly abused both humans and Pokemon in his scheme to take over the world, even planning to betray and overthrow his boss Giovanni. Even Jessie, James and Meowth were horrified by his cruel and sadistic methods. He was the first of the kind of the series- he would later be followed by similar villains such as J and Grings Kodai, who drew similarities from the Marauder from their occupations and technology used.
