Between Echo and Hunter

I suppose it's going to be Echo, given the many fan predictions about an upcoming Clone Underground show starring Echo and Rex. He needs to stay alive for that, that's for sure.

Not to mention, he is machine more than human and anybody that knows how to repair protocol droids can revive him if he perishes.

Echo

I’ll place my prediction now: I think Echo is as good as dead. Realistically, if he survived, he’d probably have ended up with Rex, Gregor, and Wolfe. But alas.

I could see any combination of the other three surviving and going off into hiding, but my gut tells me Crosshair will probably sacrifice himself, and Hunter and Wrecker will go their own way.

I think Omega will either go with the surviving members of the Batch or end up with Ventress before eventually re-emerging post-ROTJ.

This comment will probably age poorly.

I’m thinking Echo and Wrecker will be safe, given how little we’ve seen from them and underdeveloped both are. I could see them simply retiring to Pabu and living solitary lives with Omega. Now we still don’t exactly know what the finale’s runtime will be and as such, how many major deaths we can expect. With only one in mind, I’m between Hunter, as the squad’s leader and Omega’s father figure, and Crosshair, as per typical redemption arcs go.

I say Hunter, Wrecker and Echo will come out of this alive

Omega. Everyone else does when Darth Vader shows up.

^ Omega is too obvious of an answer because she's just a kid. Please pick somebody else.

I did. I picked Echo. But in reality I think they’ll all die except Omega.
