Grox is an inhabitant of the Crimson Waste. Huntara sought out her help in The Valley of the Lost, but Grox had already agreed with the Horde to turn over Huntara when she made contact with her old friend.
Grox appears to be a similar species to Grizzlor; she has a dark purple mane of hair framing her face, with eyebrows of the same color. Grox's eye is purely yellow, while the other is covered by a black eyepatch. She also has robotic arm with a red scarf wrapped around it.
She has no moral compass, unstable in nature, and is a traitor.
Grox had appeared to already have had somewhat of a history with Huntara, in The Valley of the Lost), Huntara had been glad to see Grox, though Grox betrayed Huntara by turning her over to the Horde, reminding Huntara to never trust anyone in the Crimson Waste.
