Thanos was certainly a presence before Avengers: Infinity War.

We heard Loki mention him in the first Avengers film and even get a glance of his visage. And Nebula talked about him during The Guardians Of The Galaxy Vol. 1 as the father of both herself and Gamora.

What we didn't know about Thanos is that he had an almost completely different aesthetic on the concept artists' page before he made it to full terrifying chin-presence in Avengers: IW.

Take a look:

Yeah, Thanos was almost wearing an entire white suit and DJing a white party.

Crazy, right?

Just kidding. But we would pay money to go to that party.

THIS is how Thanos looked in the film:

Okay we'll stop pulling your leg now.

This is REALLY what Thanos looked like in the film:

And here is an early design of the Crimson Chin's alter-ego himself from a member of the movie's team:

We immediately can see his face is pretty similar, if not a bit more purple than crimson.

What is not similar, at all, is the costume.

For one, it looks like a bit like athleisure.

For another, though, it does make Thanos look a lot different than the Marvel heroes.

The look from the film is almost an Iron Man/Thor look.

It has the same basic shape, complete with shiny chrome helmet.

That other Thanos almost looks like a different RPG class of Thanos before he levels up.

Here are the two side by side.

The new Avengers: Endgame is slated for release on April 26, 2019.

In preparation, you can study up on Avengers: Infinity War, available in multiple formats here.

Thanos will likely sport a newer look in Endgame, too.

Here are some fan theories:

Which one is your favorite Thanos *look* so far?

And is it April yet‽
