General Grievous

Grievous is ruthless and cold-blooded, especially towards clone troopers and Jedi. He can become very angry if he is not given what he wants and will often bash the head of a nearby battle droid in.

Grievous, in addition to being the supreme general of the Separatist army, also has several lightsabers that he collects as trophies. He is believed to have killed more than 40 Jedi throughout his career as a general.

Grievous has several disadvantages, such as not being able to use the Force because he is a cyborg, and when he deploys his four arms, if he makes a mistake they can easily cut off an arm or a hand.

Grievous also has several advantages, he has supernatural strength, he has four arms that he can deploy whenever he wants, and he is quite tall measuring 2.16 cm (according to Google) he also has his speed that although it may seem that he is slow, he really is not. He can also lie on the ground and go like a spider when he has his four arms (you can see it better in Star Wars Battlefront 2 or in Revenge of the Sith)

Grievous has respect for few people, but among those people is Count Dooku, his master and Darth Sidius (I had nothing else to say and I put that thing xd)
