The Champions of Thanatos primarily wear black Power Armour. The insets of the shoulder pauldrons are bone. The Aquila or Imperialis on the chest is yellow. The black squad specialty symbol (Tactical, Assault, Devastator or Veteran) is indicated on the right shoulder pauldron. A white Roman numeral centred on the squad specialty symbol indicates squad number. The colour of the shoulder pauldron trim indicates company number in accordance with the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), etc.
The Champions of Thanatos' Chapter badge is a large, white skull with stylised, black wings protruding from its sides, centred over a pair of crossed ebon scythes, on a field of bone.
