The Super Friends never had this much intimacy, manly tears or phallic imagery. Lots of things in this comic would be bromantic on their own, having them all in the same story (and everything about the penis aliens, right down to the "mating ritual") seems like really-not-an-accident. If it is accidental, then a whole lot of effort went into elements of the story that seem awfully orthogonal to the idea of "SuperFriends Bats and Supes have a play date" that you're reading into it.
