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_Minxis 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)
