(Warning - the following contains theoretical SPOILERS for future episodes of DC and the CW's Legends of Tomorrow. Proceed with whatever level of caution that suggests to you is wise...)
Now, DC and the CW's Legends of Tomorrow may already be filled close to bursting with superheroes, villains and vaguely anti-heroic folks in capes, but that doesn't mean that the rest of its debut season isn't set to bring us a whole heap of additional DC 'legends' to keep them company.
In fact, as it turns out, the good folks over at DC might just be hinting at who we're going to see. After all...
It Sure Seems as Though DC are Teasing the Arrival of an Iconic Super-Team
(Note, this is where those aforementioned theoretical spoilers come in...)
Specifically, that one, just above - the Justice Society of America.
The reason for that particular suspicion?
DC Keeps Teasing Ex-JSA Members on Instagram
In fact, as part of an extended teasing of the show's Easter eggs, DC's official Instagram account has been teasing long-standing JSA members for a while now, from Dr Mid-Nite (above), all the way through to his contemporaries...
And even honorary JSA member...
All of which - combined with the presence of founding members Hawkman, Atom (albeit an alternative version of the hero) and (the Jay Garrick iteration of) The Flash in the Arrowverse - suggests that the JSA might not actually be all that far away from making an appearance.
Keep your eyes peeled for Mr Terrific, Wildcat and Spectre then, gang...
