As above. What do you paint up all of those little Primaris helmets on your bases and enemy models as? Like, say, on Abaddon's big spiky star thing or his base, under the new-old Noise Marine's hoof or on the new Chaos Marine sculpts' power packs? Do you paint it up as one of the Chapters you play, or do you have a "whipping boy" Chapter you prefer to beat the Warp out of?
Edit: After a moment's research, it turns out the newer CSM actually don't have Astartes helms impaled on their power packs. I know such a Chaos power pack exists/existed, in plastic, no less, because I have a friend who took some new CSM, some FW World Eaters pauldrons and some Khorne Berzerkers and did a nice kitbash for properly sized Berzerkers. At least two of the models have power packs with Astartes helms speared on them.
