What do you mean portray? Like make a character of one? That's not something I planned for, and they are (spoilers) a hivemind so Seekers, Hunters, their big boss, that's off the table, but I guess if you wanted to make an alien... It'd have to be really well done, I planned on a few Streamer Realms but I hadn't really accounted for another planet like Earth with it's own species and stuff to be like... on the map I guess? Aside from the Seekers I mean, and we do go to Earth right after, it'd potentially totally change the dynamic of interacting with mundanes...

But yknow what, I'm open to the idea, though they'd have to be in the same boat as everyone else; their world may be more or less advanced but for the most part no supernatural Streamer powers, it'd be all new to their world as well and your char wouldn't have any advantages over the other Streamers. Unless it was like a minor biology thing like good nightvision or something.
