Interested, but this mention here gives me pause.

<Snipped quote by Retired>

What standards are you imposing for your selection? The three properties you listed aren't giving me a very clear idea of what you do or don't want.

There are no specific set of standards. At least, not in the sense that you might be looking for. This RP is designed so that character creation is rather open-ended. There are some things I absolutely won't consider, such as a massive transforming Autobot for obvious reasons, or fourth wall breaking characters for the purposes of maintaining a consistent tone. 

These are going to be characters that were forced into gladiatorial death games, and must now traverse different worlds. Being able to relatively blend in - hence no Transformers - to varying environments might be useful. I also am trying to keep a mostly serious tone. Lighthearted posts can and will happen, of course, but having a Steven Universe or Blossom tagging along with Moon Knight and Cyclops would probably be narratively jarring. Those are things I would be hesitant or outright unlikely to accept. But it's hard to say for certain until and if I see such concepts.

If you have something more specific in mind that you're wondering about, feel free to ask. But there aren't any hard "you must do this" rulesets in regards to characters. For the most part, I think advanced roleplayers are capable of determining what makes the most sense when it comes to fitting setting and tone. With me, having a cohesive, coherent narrative is the most important thing.

What would you think of a Star Wars entry, such as, a mirror universe where Palpatine was a good guy for instance?

I think it could be just as feasible as most other concepts. I will say, though, that everyone should consider how much a character might be a Gary/Mary Sue. I absolutely will accept powerful characters, but keep in mind this is a group RP and so no single character should be able to solve everything. And the Force can very much be a "I solve this singlehandedly" powerset. 

I would recommend people consider DC and Marvel properties primarily as that is the majority of what will be explored throughout the RP. However, there's nothing inherently wrong with Star Wars or other properties outside of those sources, and a SW concept will be judged equally alongside everything else. Just keep in mind that, while non-DC/Marvel entities are allowed, the focus will be on those two.

On a more serious note, though, I’m ruminating on a Steve Rogers as Nomad concept in a time line where the Axis won WWII and the U.S fell to Fascism. Some real Man in the High Castle shit, if ya dig me.

That concept would fit beautifully with one of the alternate worlds I have planned for the group to land in. One of the original realities I had planned to touch upon from the very first rendition of this game is very similar in premise to that.
