On the left is Captain Rex from a recent Rebels TV episode. On the right is Gideon Argus.

The question is, is Gideon an old clone?

This has been also been discussed over on BGG . While nobody really knows (obviously), I will echo my same sentiments I did over there:

That's uncanny. I can't imagine that's a coincidence.

Not sure why this is in campaign discussion. But pretty sure its coincidence. Black guy with white beard isn't exactly super natural. That'd be like saying Lunae Minx http://starwars.wikia.com/wiki/Lunae_Minx is Diala just because they're the same color/species.

I put in campaign because its relevant to the characters involved in the campaign? There's no "general crap" forum here.

I will apologize, I didn't realize it had already been discussed elsewhere. I only figured it out myself this week (I dont watch Rebels)
