McFarlane Toys/Halo Series 8
From Halopedia, the Halo wiki
The series is unique in that McFarlane based the figures off of fan requests.
The Brute Captain figure is based off the Brute Captains from Halo 3: ODST. It is unique in that appears in the manner one would see them in VISR mode. It is armed with a Kewu R'shi'k-pattern plasma rifle and Spike Grenade and features 26 points of articulation.
Additionally, it is painted with glow-in-the-dark paint. However, the paint glows green, designating it has a friendly in VISR, despite the fact that Brutes are enemies.
The body is an updated mold of the Rookie's body, due to complaints about parts falling off, etc. However, there is still no weapon storage available, and the paint job actually makes him look quite unlike his counterpart in the game.
The figure also includes an ODST helmet that can be taken off to reveal Buck's face underneath.
This Master Chief figure is based off the Master Chief from Halo 2, as it has no battle damage on the chest piece and the visor on the helmet appears to be slightly wider, as it is in the Halo 2 game. It is equipped with dual Kewu R'shi'k-pattern plasma rifles. It features 26 points of articulation.
He is taller than the average Elite figure, but the mold makes him difficult to pose. His energy swords are also hard to remove, even more so than the Arbiter figure from Series 2. They are also block coloured a deep purple, instead of the traditional white fading into blue.
The UNSC Marine figure is based off the UNSC Marines that appear in Halo 3. It comes with a Battle Rifle and has 26 points of articulation. Interestingly, the Battle Rifle is the full-sized scale, used by Spartans, not the smaller one that came with the ODST figure, which is the same size as this figure.
As of now, there is only one color for the Ascetic Harness: silver, with red as a secondary colouring. This figure comes with dual Paegaas Workshop Spikers and has 26 points of articulation. Like all other McFarlane figures, you can interchange armor between the figures.
It is the first figure to come in the Ascetic Harness.
The Elite Combat figure comes in an orange color. It includes dual Paegaas Workshop Spikers and is an exclusive to Toys 'R' Us in the US and Canada.
The Spartan EOD comes in a white color, with green detail coloring. This figure is armed with dual SMGs and is an exclusive to Specialty Stores. Unlike previous Spartan figures, this figure has weapon storage on both legs. It has 26 points of articulation.
Spartan Mark IV
The Spartan Mark IV figure is based off the Halo Wars multiplayer figure. It is black in color and is equipped with dual SMGs. This figure is a Target exclusive.
