While only a 5POA (point of articulation) 3.75" figure from the basic SW range, this Rex figure is still great to complete your Star Wars REBELS Ghost crew – especially since he plays a larger part in Season 3 of Rebels (as at Oct 2016). He has a nice likeness to the aged & battle weary Rex we see in the cartoon, and also includes his old Clone Trooper helmet (though it is a tad larger than the helmets on your other Clone Troopers from the Clone Wars range). Collectors like myself will always have a soft spot for Rex (old or young) because has and continues to be such a great character.
