The Nightbrothers harass you endlessly as you navigate Dathomir.  They are “skinned” in-game as both red and yellow (similar to Maul and Savage Oppress), so there is repaint opportunity for Hasbro.
The figure would basically be a shirtless Darth Maul.  Like it or not, it would sell and sell well.  Additionally the Nigthbrothers in the game are further distinguished by their weapons.  The in-game Tactical Guide designates Nightbrother Warriors, who use melee weapons, and Nightbrother Archers, who use energy bows (and get annoying at times).  Hasbro could potentially milk the tooling for two separate figures with different accessories.  As they are a somewhat non-descript enemy, they are tough to place higher on the list, but fans of the game would be sure to buy multiples.

If Hasbro released a yellow skinned Nightbrother Warrior and a red skinned Nightbrother Archer, I would probably buy three of each and mix and match the accessories.
