I dunno, I just know that I've seen plenty of Batman-only toy lines over the years. All I'm saying is, if you're going to make 85% of your DC line Batman, then why not just do a Batman line?
My take is…the current retail or management environment would only allow for single product line for DC, at least at the moment. Batman, while still quite popular, has cooled in the past decade relative to where he was in the late 2000s to 2010s, where the character was still receiving a steady stream of appearances in movies to maintain popularity (plus appearing on DC animated features and shows). A LOT of those initiatives have slowed, which I think has had the knock on effect of diminishing consumer momentum for the character on the whole.
When Spin Masters launched their DC stuff in 2020 with Batman, alone, it was fairly successful becuase, well, “Batman sells”. But the DC Superhero Spin off struggled to match that pace. To the point the line would get fairly hefty hiatus periods.
Mattel, with how they’ve shifted their management priorities over the past half decade, WANTS a line that provides a wide spectrum of characters at an accessible price point. After all, all those decades of DC films, shows and animated series are still floating around the myriad of streaming venues as well as Gunn’s more “open universe” perspective in the new era of DC films (2025’s Superman likely introducing many younger fans to Mr Terrific, Guy Gardner, Hawkgirl, AND Metamorpho!).
But history shows that Batman MUST be the anchor. He (and his broader “brand family”) are what is going to maintain this segment to allow Mattel to touch on a wider variety of characters
