Possible Republic Commando Full Squad

Not likely at this time.

This Scorch isn't the one from Delta Squad. He's the one from Bad Batch Season 3. He's the only member of the squad who's been made canon at this time.

Don't get me wrong. I'd love nothing more than to be proven wrong. It'd just be extremely unlikely as CG doesn't dip their toes too much into non-canon characters and, if they were to do so again, Delta squad's not likely to be very high on the list of choices

The entire Delta Squad has been made canon since their little cameo on Clone Wars
But Scorch is the only one who have had more screen time in any show
