Ryan Reynolds may have just thrown the Marvel fandom into overdrive. The Deadpool star posted a cryptic image on Instagram late last night — a black-and-white Avengers logo, defaced with a bright red spray-painted “A” in Deadpool’s unmistakable style — sending fans into a frenzy over whether the wisecracking antihero is finally joining Earth’s Mightiest Heroes.

A year after he joined the MCU in Deadpool and Wolverine, Ryan Reynolds seems to be teasing a Marvel return in an upcoming Avengers movie. Reynolds took to Instagram to share the tease. In the picture, which you can see below, the Deadpool actor posted the Avengers logo with what looks to be the anarchist symbol spray-painted over the top.
