Obliterator from the Cleaved chapter.
The Cleaved are a warband of Chaos Space Marines of unknown origin who serve the Plague God Nurgle.
The Cleaved wear pale, flesh-coloured power armour that seems to have a strange, oil-like substance constantly oozing from the joints of the armour like black blood. What remains of the Chaos Space Marines within their sealed armour, or how they have been mutated to release such a discharge, none can say.
