Well, when...Jetfire was dying, he gave Optimus Prime his wings, and jets, which allowed the Autobot Leader, to save the day! Hopefully when, Sentinel Prime, goes to that big scrapheap in the sky, Optimus will be allowed to be around for...Transformers 4, even if the, Master of...Bayhem, leaves to direct something else! I...Love the look of Sentinel Prime, and do not get why so many people hate on this...Epic, Transformers Franchise!
