The mask it has is temporarily.
The Hixo Armor is my own idea of my own Spartan armor from HALO franchise series, it can survive heated areas for 24 hours it can also survive heated water and extreme cold temperatures but for 12 hours. It also has jetpack system build into it (with the us of 7 minutes) just without the thing on it’s back like in HALO 4 which the weapon would phase throw it.
The main weapon is called the RI-70(Rampage Incineration) its a submachine gun, single shot or triple shot weapon that can penetrate almost any material.
His side arm pistol called M-16(Meltdown) this weapon shots pistol size bullets that can over heat flesh, metal, etc. like lava but a few materials can be affected to it.
The last picture with two other figures is his team there are others to come so its a small team for now.(the masks they currently wear are temporarily as well)
