The costume description for Grozz's High Republic Champion reads:
"Grozz would have made a great Jedi; he's extremely self-disciplined and honorable. The only problem would have been his love of gonkrock." -Zaina
Gonkrock is a musical genre introduced in Star Wars Hunters, and the type of music played by fellow Hunter, Rieve, in her band Corellia's Not Dead. Its name comes from the sound being amplified through GNK "Gonk" power droids.
The weapon wrap for this costume is the High Republic Branch. These are a pair of sturdy branches (maybe wroshyr branches from Kashyyyk?) decorated with the symbol of the Jedi Order.
The weapon description reads:
"Good thing Balada didn't give that furbag a lightsaber - imagine him barreling down on you swinging one of those!? He'd be TOO powerful." -Sentinel
The next Legendary costume for Grozz is Prematch Parader. This sees Grozz wearing a hooded jacket similar to what you might see a boxer wearing before his match. Aurebesh along the jacket's edge reads: HUNTERS OF THE OUTER RIM and CHAMPION.
On his back, it features his name in Aurebesh above a circular design.
The weapon wrap for this costume, Prematch Clubs, are large paddle-like clubs with turquoise embellishments. The symbol from the back of Grozz's jacket is also in the center.
The Ferrix Fighter is a reference to the Grapplers of Ferrix, the workers who dismantle starships in the first season of Andor. He wears the same helmet and overalls as Cassian Andor's friend Brasso. The game files refer to this costume as "Skilled Scrapper".
The description for this costume contains a quote from Diago, noting the reverence they have for the freedom fighters seen in the finale of the first season of Andor.
"Grozz told me about the scrap workers on Ferrix - their fight against the empire is a story close to his heart." -Diago
The weapon wrap for this costume, Ferrix Clubs, resemble the hammers wielded by the Time Grappler, who rang in the new day by smashing his hammers on an anvil atop a belltower on Rix Road. The hammers have the Aurebesh letter F, "Forn", for Ferrix stamped on them.
The quote from Zaina in the Ferrix Clubs' description directly references the Rix Road Riot in Andor:
"It doesn't take much to rise against oppressors - a simple worker's hammer will do. Or a thrown stone." -Zaina
Next up we have the Kessel Savior costume. In this costume, Grozz suits up as a Pyke sentinel, seen in Solo: A Star Wars Story, wearing the lead-lined work smock beneath a visored helmet. the game files name this costume "Kessel Liberator".
Around his neck, he wears the caretaker's code keys carried by the director of the Pyke Syndicate's operations on Kessel, Quay Tolsite.
Zaina's quote in the costume description references the primary export of Kessel: spice.
"Grozz's disguise might fool spice smugglers, but I'd recognize him an Arena-length away. I'd never tell him though - I do have a heart!" -Zaina
The weapon wrap for this costume, Saving Clubs, have a similar color and the same symbol as the arms on B8G-H0R from Solo, but the shape of the shoulders is greatly expanded. Aurebesh on the one club reads FREE.
The weapon wrap description references the Kessel Run:
"Wonder if Grozz ever made the Kessel Run. And how long it would've took him," -Imara Vex
First mentioned by Han Solo in A New Hope, we first got to see Han's Kessel Run play out on-screen in Solo.
The next Legendary costume for Grozz is Life Day Wookiee. This references the red robe worn by Chewbacca for the Wookiee holiday, Life Day, in 1978's infamous Star Wars Holiday Special, although Grozz's costume has a bit more embellishment.
The back of the robe features a large intricate tree design, better seen in the texture file.
The weapon wrap, Life Day Clubs, are very organic looking, with wooden tangles around some kind of green structure (maybe an egg?) along with sword hilts.
The next Legendary costume is Wookiee's Revenge. Grozz wears discarded remains of an Arakyd Industries Viper probe droid as armor, with the droid's large photoreceptors visible on his shoulders.
The weapon wrap, Vengeful Clubs, features more Viper probe droid parts fashioned into dangerous looking axe/clubs. The probe droid's many grasper arms can be seen at the bottom of each club.
The next costume for Grozz is Kashyyyk Champion. I'm not sure if this is a direct reference to anything, or just an embellished suit of Wookiee armor. The texture on his chest armor resembles the green material in the Life Day Clubs.
Zaina reveals in the costume description how highly regarded Grozz is on Kashyyyk:
"Grozz took me to visit his hometown and it's practically a shrine to him; there's even a museum there for his career as a pro-Huttballer." -Zaina
The Champion's Clubs are two large golden spiked balls, held in the palm of droid hands, with a ring of Aurebesh around them which reads HUNTERS, which Grozz wields like maces.
Next is another hooded robe for Grozz, the Pre-Match Robe. A palette swap of the Prematch Parader costume, it also has Aurebesh along its edge reading HUNTERS OF THE OUTER RIM and CHAMPION.
The weapon wrap, Pre-Match Clubs, is a palette swap of the very similarly named Prematch Clubs (without the hyphen), in green and purple accents.
The final costume for Grozz is Ferocious Fighter, which is a golden palette swap with the Ferrix Fighter costume.
And the last weapon wrap is Ferocious Hammers, a golden palette swap with the Ferrix Clubs. The game files refer to this set as "Ranked Recolor".
And that's all for Grozz! Next we will take a look at the Ugnaught Dizzy and his destroyer droid who compete as the Hunter team Slingshot!
