Arrow’s newest episode was an eventful one. Not only did Season 7’s overarching storyline take some major leaps forward, “Spartan” also dropped some pretty great cameos for hardcore DC fans. This episode teased the prospect of seeing both Green Lantern John Stewart and the Metal Men one day join the Arrowverse.
Maybe these cameos will never amount to anything. But we can dream, right? Here’s a closer look at the significance of these teases and what it could mean for the Arrowverse after Arrow wraps up at the end of the year.
Green Lantern John Stewart
In the traditional DC Universe, John Stewart is one of several Earthlings to wear a Green Lantern ring. An ex-military man and current architect, John is among the most disciplined members of the Green Lantern Corps. He’s also among the most popular Green Lanterns of them all, thanks in no small part to his starring role in the Justice League animated series.
