Gamorreans
The two piggish brutes looming behind Fett are Gamorrean guards, which Jabba the Hutt used to employ as well. That didn’t work out well for Jabba, so it remains to be seen why Fett would renew their contract when he took charge. Gamorreans are typified as dumb, savage, stinky, and very loyal (justice for Voort “Piggy” saBinring, the Gamorrean X-Wing ace in Wraith Squadron in the old EU!), so they were likely working for Jabba’s former majordomo Bib Fortuna when Fett murdered him at the end of The Mandalorian’s second season, and just stuck around.
