Bad Batch

Cool to see Trace and Rafa show up!
Seems like it almost has to be Ashoka they spoke to at the end, but there are a couple of other possibilities. Saw Guerrero has already shown up, so I don't think it's him, but it would be an easy tie in to what they've already established. Could be Obi-Wan, but I don't know that he's tied to them at all in the plotlines as they've been established.

I'm thinking they're going to have to operate on Wrecker's skull shortly. Wondering if once they do, they'll figure out a way to capture Crosshair and remove his as well.

I'm also wondering if any of them are going to end up being Wolffe or Gregor from Rebels. Wolffe was too well spoken to be Wrecker, though he was big enough. Maybe Gregor, but he doesn't have the gruff voice of Wrecker.
He is a little wrong in the head like Wrecker, but it seems like Wrecker is more just a simpleton rather than having "mental difficulties" like Gregor seemed to have. So I doubt Gregor is any of the others unless one of them suffers a head injury.
