Awesome character, whose fate yet remains unknown. I think this clone was the perfect choice to be the founder and leader of the 501st during the Clone wars and right-hand man to Anakin, given his rather aggressive and "badass" nature. It will be interesting to see what happens to him by the end of the show? What are your thoughts on this? I personally think, that he will be killed off by the end of the show and that there are several very interesting ways this could be done that could tie in nicely with the events in ROTS. Some things to look at:- - It's important to take a look at which clones are leading the 501st during the end of the clone wars and attack on the temple in ROTS. It seems they are Clone Commander Appo and Sergeant Fox (going by wookiepedia). - Important to look at other key 501st members like Fives, Echo....who were inducted into the 501st by Rex himself, and consider their fates. - I guess an interesting fate would be that Rex, unlike probably 99.8% of other clones, will disagree with Order 66 and turn against and be killed by members of the very team...the 501st, that he founded. - Scenario: Rex is about to "execute" a Jedi in accordance to Order 66, one that he grew fond of, only at the last second to point his blaster to either side of the Jedi and take out the clones next to him, along with several other key clones - perhaps even Fives and Echo (who perhaps agree with order 66, like most others), only to perhaps be killed by Anakin himself (then as Darth Vader), or gunned down by the men who will succeed him - Appo and Fox, after receiving a beating from Anakin. Anakin then promotes Appo and Fox after Rex is killed and raid the temple/continue to raid the temple.
