The Avengers is a Loyalist Space Marine Chapter of unknown origins and Founding. Nothing else is known about them in Imperial records, except that they were created some time after the Second Founding.
The Avengers Chapter primarily wears bone white Power Armour. The Aquila or Imperialis on the chest, the power pack and shoulder plates are red. The trim of the shoulder plates is bone white. The white squad specialty symbol (Tactical, Assault, Devastator or Veteran) is indicated on the right shoulder plate.
A black Roman numeral centred on the squad specialty symbol indicates squad number. The identical iconography (mirror images), on both knee guards, indicates company number in accordance with the Codex Astartes.
The Avengers' Chapter badge is a white maltese cross, with a roundel in the centre. A large white skull sits in the centre of the roundel on a field of red.
