Arrowverse Fans Are Loving Grant Gustin's Green Arrow Butt in New "Elseworlds" Poster

Fans just got a pretty major dose of "Elseworlds" in the event's new poster -- but one character's pose has caught quite a few fans' eyes.

The CW recently released a new piece of key art for the upcoming three-night Arrowverse crossover event, which you can check out below. The poster features the event's slew of characters, including Barry Allen/The Flash (Stephen Amell) and Oliver Queen/Green Arrow (Grant Gustin), whose identities have been switched thanks to a warping in reality.

While fans have already seen what Gustin looks like in the Green Arrow costume, this particular shot (and the pose he's in) has garnered quite a reaction. As some have been quick to point out online, Gustin's Green Arrow appears to be channeling the "Hawkeye Initiative", as the pose he's making looks physically impossible, and just so happens to show off his butt.

Here's a round-up of some of those tweets.
