>>9554601His cockpit actually opens up, too - but you have to bend his nosecone down first. Inside is this weird mechanical block that has a peg hole in it; not sure what it's significance is, but once it's out, it leaves a space large enough to fit a Headmaster/Titanmaster/Primemaster, as demonstrated by Cogman here (the only Headmaster I own. I've mentioned my dislike for the concept of Headmasters before). The top of his backpack opens up (right behind the green canopy) to reveal a pair of sockets that perfectly fit two more in folded up configuration, meaning he can hold a total of three little companions at once. Also forgot - the purple Autobot insignia actually rotates around to reveal a red Decepticon one, so you can have him change factions on the fly.
