Fan Casting Post-Credits Scene in The Champions of Shazam!

After Sabbac's defeat, Black Adam decides to stay in Kahndaq. In a moment of the night, he is called by a mysterious hooded figure: - I imagine it's you they call 'Black Adam'. - And would you be? - I knew about you for what you did here, although I also know that you and Superman already had a... disagreement. - Where are you going with this? - I think I have an offer that might be of interest to you. It's not like Justice League is going to do it. Teth-Adam decides to accept the proposal, as he walks alongside the stranger. Before the screen goes dark, the figure asks a question: - Do you believe in Fate, Black Adam? - Why would I believe it? - I thought you would say that (laughs).
