Again, not to pick nits - but does this have to be the "non-Star Wars" comic thread? I've always been of the impression that all comics were allowed to be discussed in the comics section, which would make this thread now officially off topic. Just my thoughts.
I would imagine El Chux, that like most other comics - time does not travel in a typical fashion in the G.I.Joe comic. Otherwise, in order for Snake Eyes to have been a Vietnam vet as he was said to have been in the original G.I.Joe comic series - he would've had to be between thirty and forty years old back in the '80s when he was created. He therefore would have to be in his fifties, possibly pushing SIXTY in the current book! Ninja or not...that's still pretty durned old to be fightin'! They'd probably have to be drawing Scarlet a bit differently also.
