Captain Marvel joins the League while Superman is off-world.
While being interviewed, Marvel sorta endorses Lex Luthor’s presidential campaign. This gets him called on the carpet by the League - mostly Superman.
While at a charity function given by Luthor, Supes overhears Luthor talking about a “device” and his “escape plan”. Supes finds a device under the plaza where the event is taking place. Supes evacuates the plaza and goes after the device (supposedly a kryptonite powered generator).
Marvel comes in and he and Supes have a wicked knock down drag out fight.
I didn’t know Marvel was so powerful!
Of course, I’m on Superman’s side. Luthor is slime and Marvel refuses to see it.
Can’t wait for the conclusion!
