ComicVine is a fan-maintained database (with a not very transparent editing process). Plus, it's a very common phrase. The image itself is from the Public Enemies arc, which featured the fall of Luthor back into villainy.

Granted, his true colors are green and purple. It's entirely possible he'll don the warsuit. But a caption under an image on a fan site that is, potentially, there for years, is not an indication of what might happen on the show.
