Scaramouche the Merciless

Scaramouche the Merciless is a one-shot villain in the Samurai Jack series. He is a robot assassin capable of controlling objects with a flute and his voice. He is voiced by Tom Kenny.

Personality
Scaramouche is a very remorseless psychopath who who loves slaughtering villages to lure his enemies out for his own enjoyment. He is also extremely loyal to Aku as he always wants to please him and become his favourite assassin and servant by any means. Unlike other robots sent to kill Jack, Scaramouche is very boastful and talkative. Upon noticing that Jack was without his sword, he proceeded to mock him for it, to the point of calling Aku to boast that Jack had lost the weapon. He has a tendency to call anyone he meets as bae or baby, even his boss Aku. He is also extremely arrogant since he self-proclaims himself as Aku's favorite assassin while his power is vastly inferior to many of Jack's old foes like Demongo or even DJ Stylbator.

His arrogance leads to his downfall since he lets his guard down long enough for Jack to use his knife, which was imbued by Scaramounche's own magnetic force from his own knife, against him and cripple his neck (the source of his ability) as well as heavily injure him.

In the face of death, he praises Jack's fighting skill, likely a weak attempt to talk his way out of his fate, before Jack chops him in half with his own sword, showing an act of cowardice when losing.
