FYI, that's the Integrity Toys Jem, only available at SDCC in 2012. I wish they'd used a vintage Jem doll, though they probably couldn't get the poses that they wanted with a vintage 1986 doll.

Eagle Eyes will note that Joe is supposed to be a Talking Commander from 1970 but his dog tag doesn't actually go into his chest- rather it sits on his neck. Methinks that he's a Land Adventurer posing as a Commander. Trying to impress Jem? -Omar
