High Magistrate Greef Karga is a fictional character in the Star Wars franchise who appears in the Disney+ television series The Mandalorian.

Elements of the character's background have deliberately been kept mysterious, though it was revealed in the first-season finale that he was previously a disgraced government official, and Weathers said his backstory would be further developed in the second season.

For his performance in the second season, Weathers was nominated for the Primetime Emmy Award for Outstanding Guest Actor in a Drama Series.

[10][11] Greef next appears in "Chapter 3: The Sin", during which he informs the Mandalorian to bring the captured Grogu directly to the Client.

[12] Greef only survives because he had two ingots of beskar, a rare steel that the Client provided as payment for the Grogu's bounty, inside his vest pocket where he was shot.

[16][18] During their voyage, the party is attacked by pterodactyl-like creatures, and Greef receives a poisonous slash that would have been fatal,[18][20] but Grogu uses the Force to heal him.

[17][18] The plan goes wrong, resulting in the trio becoming pinned down inside a bar by Imperial officer Moff Gideon and his stormtroopers.

[22][23] At the start of the first-season finale "Chapter 8: Redemption", the group engages in a brief gunfight with the stormtroopers after the IG-11 arrives with Grogu to provide assistance.

[22][24] The group escapes the building via the sewer system,[24][25] where they travel to a hidden Mandalorian covert and find most of the warriors there have already been killed by the Empire.

Greef is present when IG-11 sacrifices himself to eliminate a large number of stormtroopers to ensure the group's escape, and he survives an attack by Moff Gideon in a TIE fighter, which the Mandalorian repels.

[24] Afterward, Greef decides to stay behind on Nevarro and rebuild the Bounty Hunters' Guild,[24][26] and he invites Cara Dune to work as his enforcer,[8][25] which she accepts.

Now the magistrate of Nevarro, he worked to eliminate all Imperial forces on the planet, aided by Cara as his marshal and an unnamed Mythrol as his assistant.

The scientists attempt to destroy the evidence, but before they can do so, the Mythrol uncovers a recording from Dr. Pershing that reveals he had been transfusing Grogu's blood, which has a high 'M-count', into test subjects.

The Mandalorian flies from the base to retrieve his ship, using his jetpack, whilst Greef, Cara, and Mythrol steal a stormtrooper transport.

Greef kills the last scout trooper, but TIE fighters launched from the base chase after them, disabling the transport's cannon.

As the TIE fighters close in on Greef, Cara, and Mythrol, the Razor Crest appears and destroys the Imperials.

After the Mandalorian receives the promised repairs to his ship and departs from Nevarro once again with Grogu, Greef is visited by New Republic pilots, who invite him to help stop whatever the Empire is planning.

In "Chapter 21: The Pirate", Gorian Shard attacks Nevarro, seeking revenge on Greef for killing one of his men.

In "Chapter 23: The Spies", Greef gifts the Mandalorian with IG-12, a rebuilt IG-11 which now serves as a mech suit for Grogu, allowing him to communicate saying "yes" or "no".

[35] Greef is a mysterious character,[7][36][37] and Weathers has said it was a conscious decision by the writers to keep aspects of his history and motivations cryptic: "There's some real strong indications that give you some idea of who he is, but we never let on completely.

[40] Greef Karga was first publicly unveiled during the Star Wars Celebration convention in Chicago on April 14, 2019, along with the character Cara Dune.

He felt there was a theatricality and "larger than life" quality to the character, and he deliberately performed some of his lines in a showy and melodramatic way as a result.

[54][55] Weathers called The Mandalorian one of the "most exciting projects" of his career,[36] saying: "Being a part of this is one of the greatest things that's happened in all of the years that I've been in entertainment.

"[1] He said he was very impressed by the quality of writing in the scripts,[56] and that he particularly enjoyed his character's shifting allegiances and unpredictable about-faces: "It's much more interesting to play someone who is not all of one thing, not one-dimensional.

"[7] Weathers said he knew little about Greef Karga's backstory before playing the character, and that he did not want to know it because he felt the mystery helped him convey a sense of ambiguity.

[59] Weathers said he particularly enjoyed working with the director Deborah Chow during the filming of "Chapter 3: The Sin",[14][59] because she had planned what she wanted to do for the episode very precisely and meticulously in advance.

[14] Weathers' action sequences in "Chapter 3: The Sin" took a particularly long time to film due to the many elements involved in the shootout scene.

[22][63] After the first season concluded, Weathers thanked his fans for their support, writing: "Your enjoyment and appreciation for the work done by the creators, directors, cast and crew fills us all with pride.
