What's the grammatical structure of this sentence?

Question

Does this sentence "as were all things Thanos" means "as if all things were Thanos?" If so, is it common to reverse "were" while omit "if"? Could anyone help with its grammar or structure? Greatly appreciated if more examples could be given, many thanks.

Here is the sentence in the context:

With Spider-Man safely earthbound, Iron Man attached himself to the ship and began using lasers from his gauntlet to cut into the hull. A piece flew out and Tony hoisted himself in. Looking around, it was like nothing he had seen before, yet strangely familiar, as were all things Thanos. Ghosts floating in his mind for six years ever since he first made contact during the climax of the Battle of New York. Pressing a button, his boots activated stealth mode and he silently began to examine the invading ship.

I had to look up Thanos to understand the usage. For anyone else who doesn't know, he's a fictional supervillain appearing in American comic books published by Marvel Comics (hence, a natural enemy of superhero Spiderman).

Standard English syntax would require an adjective / adjectival phrase after the noun phrase all things. In a typical context such as All things bright and beautiful, we can interpret the syntax as a "reduced" version of All things which are bright and beautiful.

But in OP's context, Thanos is a proper noun, not an adjective, so it's a slightly stylisted / non-standard construction which we can understand as a reduced version of all things concerning Thanos. That's to say everything to do with Thanos, everything about him was simultaneously both "previously unseen" (unfamiliar) and familiar (it's up to the reader to imagine for himself exactly what that might mean or feel like).
