It remains to be seen whether this is the Ronnie Raymond fans know and love, or a potentially evil Earth Two doppelganger, but either way, Robbie Amell is back in his Firestorm outfit.

The photo, tweeted out by @Canadagraphs, shows Amell suited up and ready to flame on in his Firestorm outfit, complete with powered-up quantum splicer. While the tweet specifically points to "The Flash," it's also possible the actor is returning for an appearance on "DC's Legends of Tomorrow," as Victor Garber, aka Prof. Stein, aka the other half of Firestorm, teased last month in an Instagram post.

In early December, Amell tweeted his own Firestorm related tease, sharing a photo of the splicer with the text "Hello old friend." and a fire emoji.
