What worlds/factions would you like to see thrown into the same universe?

What worlds/factions would you like to see thrown into the same universe?

Not as in "who would win?", but rather who's interactions would be most interesting?

I would put Wayne and Stark industries as opposed super conglomerate mega companies. With the caveat that each is deeply suspicious of the other.

>not adding in Weyland-Yutani
It's like you've never even gone one a bug hunt before.

>Tfw you realise the BIONICLE universe and the Transformers universe share the DC universe
>Tfw no crossover happened

Elminster in Dark Sun.

Even though I'm not that big a fan of Attack on Titan I've always wanted to see how bad Kratos or The Incredible Hulk would fuck up the titans and some people.

Also anything with modern soldiers going into a high fantasy setting makes me diamonds.

I would insert the Halo franchise into the Star Wars expanded universe, it would be extremely interesting to see how the various factions and characters would interact.

I'd Stark industry and Lexcorp big-ass technological armsrace and dick-waving contest.

It would be capitalism at its finest

oh and Wade and Slade banting

>Who's interactions would be most interesting?
Transformers in any Sci-fi setting. Stealthfully infiltrate the Imperium or the Empire or whatever sci-fi setting.
But cybertronians are spread out to be a universal threat so you'd end up with cool micro stories.

>Transformers and Dr. Who are already tangentially a thing, forgive the marvel part.

At the very last minute before they land on their respective adopted worlds, Tzeentch switches out the contents of baby Kal-el's spaceship with that of the XI Primarch's incubation capsule.

I assume that being raised by the Kents Mr. (?) XI turns out more or less the same, personality wise. However if he decided to go into superheroing he's still gonna make for a very different Superman:

>can't fly
>no heat vision
>no x-ray vision
>not as physically invulnerable as Kal-el
>can't bench-press the planet
>fuckhuge stature, meaning a secret identity probably isn't possible

Kal-el on the other hand...so much depends on what kind of world he lands, who raises him, does he or does he not get corrupted by Chaos, and if/when the Emperor finds him, how do they react to each other? Clearly Emps is going to be like "whoa, I don't remember designing this" but on the other hand, a Primarch who grants you instant air superiority wherever he's around would be quite the bonus. Not to mention the whole bench-pressing the planet thing.
