General Grievous

General Grievous is the supreme cyborg commander of the CIS Droid Army and a major antagonist in the Star Wars universe. He first appeared as a minor antagonist in Season 2 of the Legends 2003 miniseries Star Wars: Clone Wars, and later served as the main antagonist of Season 3. He is also the secondary antagonist of both Star Wars: Episode III - Revenge of the Sith and the 2008 TV series Star Wars: The Clone Wars, and a posthumous antagonist in the 2019 video game Star Wars Jedi: Fallen Order.

Why He Rocks

 * 1) He is a very intimidating threat in the Legends continuity and the 2003 series.
 * 2) He's shown to be a great warrior. As he fought 5 Jedi and kills everyone of them.
 * 3) His backstory is a bit heartbreaking, where he lost his love interest and his people suffering from starvation.
 * 4) His hatred against the Jedi is pretty understandable, seeing how he was lied to by Count Dooku.
 * 5) His voice in the 2003 series sounds really threatening compared to how he sounds today.
 * 6) He is basically a foreshadowing of Darth Vader.
 * 7) His fighting skills are awesome in the 2003 series.
 * 8) His design is unique.
 * 9) His character development is pretty good in legends, unlike how he was portrayed in Revenge of the Sith and 2008 series.
 * 10) Iconic theme song.
 * 11) Some memorable lines like "Run Jedi, run. You have only prolonged the inevitable." "Jedi scum."

Bad Qualities

 * 1) Sadly, he was butchered in Revenge of the Sith and the 2008 Clone wars series. As he treated to be much weaker in both and even died in a pretty lame way.
 * 2) He talks too much.
 * 3) He gets beaten by gungans, when he should've have killed them in a second.

Trivia

 * In his first appearance in the Legends miniseries Star Wars: Clone Wars he was significantly more powerful than in his later appearances, being able to defeat multiple members of the Jedi council at once with relative ease.
