*facepalm* That’s just an old superhero trope. You could’ve put any team of supers in there and it would still work. People are so obsessed with references that they see them in generic stuff like that.
The Justice Leaguers are in a perfect V formation; the EqG characters, not so much. And the individual poses only match in one or two cases. Calling it “a reach” is being charitable. (Though Tonarella is positive about it, at least, framing it as an homage instead of a ripoff.)
