Strongest 40k character/thing that MCU Thanos can fight

[Masonicon]

what's the strongest character/thing from Warhammer 40k universe that MCU Thanos(with all 6 infinity stones) can fight?

[The Arbiter]

I'm not intimately familiar with 40K, but one would imagine being able to snuff out 50% of a Universes life would put him up there.

I know there are various "gods" in 40K but I don't know their feats.

outside of the warp, there really isn't much to challenge him.

inside of the warp? not sure what big T can do, mainly due to the very nature of the warp itself.

Keep in mind that reducing the universe's population as dramatically as he did with the snap would have SEVERE repercussions in the warp as it would effectively cut off half it's food supply

the Necrons would love him

what about slaanesh? if any of who thanos snaps out are eldar, wouldn't just make him/her stronger since he/she eats eldar souls?

[Hiromi]

Don't think it necessarily makes him stronger, so much as it's just something it does, sides I don't even know if that's still a thing since Ynnead's awake/exists now, in any case even if it does still work that way the amount of souls it got would be relatively trivial as it'd only be the Dark Eldar that were killed, since all the Craftworld would either be on the craftworld and thus protected by the infinity drives or have soul stones, and Eldar are relatively insignificant anyway, the loss of all the trillions of human minds it draws power from would be FAR more noticeable

I'd say Thanos just being in the warp would naturally amp Slaanesh and Khorne due to their natures as embodiments of excess and murder respectively, as they'd just be feeding off the all excessive murder he's running around causing. Which would further throw things outta whack for a valid comparison. But as the 40k Chaos Gods don't really have much in the way of feats that I know of, I'd say Thanos beats them, but will acknowledge I'm not the most adept with 40k lore, so they could have feats that put them at skyfather level, so IDK.
