6 Best Uses For Henry Cavill In DCEU's Future

6. A Mentor In A Supergirl Solo Movie

Zack Snyder planted the seeds of a future Supergirl appearance way back in Man of Steel, with an opened pod visible in the background at the Fortress of Solitude. While having refuted this claim in the past, he recently changed his mind in the wake of the Snyder Cut announcement, even declaring that Supergirl herself will appear on HBO Max in his new cut of Justice League.

Separately, there have been talks in the past few years of a Supergirl movie in development as part of the DCEU, and it would seem like a missed opportunity not to cast, and introduce the character in the Snyder Cut, even if only as an amuse-bouche to her own movie.

But importantly, the character of Supergirl, while fleshed out well enough in her own right, exists because of, and was inspired by, her cousin Superman. With Cavill's future more secure as the man of tomorrow, why not place him as Supergirl's mentor in the movie, showing her the ropes and teaching her how to use her powers?

Considering that Superman was forced to kill his only other Kryptonian brethren in Man of Steel, the impact on him having not only someone of his own species, but indeed his own family, with him on Earth, would be a truly interesting sub plot for Cavill to play.
