The recent Batman vs. Superman movie, was completely lifted, from a 1980's comic book story arc, known as The Death of Superman. It was a HUGE thing at the time, because , like the movie, they were going to actually KILL Superman. This was a MASSIVE event in the comic book world. And , like in the movie.......he does, actually DIE in the comic book, as well. Funeral, burial, the Whole 9 yards.
But where the movie ended.........is at the funeral. The comic books, then went on for MONTHS.......about what happened NEXT.............and he actually, sort of, kinda of returned, not once, not twice, but 4 different ways.
they introduced 4 new characters, all claiming to be Superman, but in some new changed form.
One of them, was in fact, STEEL. A big burly black guy....(a blacksmith, supposedly) -....who was buried in the rubble of the fight......but then emerges from the rubble...... determined to take Superman's place.
a little like Iron Man, I suppose, he fashions himself a SUIT, out of .......you guessed it........STEEL.......
(since Superman was the Man of Steel, get it) .......and starts fighting crime, under the name of STEEL.
(so he keeps the Big S, ya see? ) So he was a Black Superman, in that story arc.
The Others were Super BOY.....(a clone experiement, ended prematurely, so he comes out still a teen, instead of full grown) Cyborg.....supposedly Superman......but the damaged parts that killed him, were rebuilt with Robotics.....(but he's also more evil) ........and then also a Pure Kryptonian Superman, who supposedly is created with some Kryptonian device called the Eradicator. (Superman.....but colder, less human....more strictly logical......like Spock, kind of, who has lost all his humanity. )
The battle rages on for months, (in the comics) over which one is the TRUE Superman.......until at long last........the one and only REAL *dead* Superman, actually comes back to life and settles the matter.
That's why REAL fans of the *Movie* knew damn well he's not REALLY dead........and he will be back.
There was a "blink and you missed it" teaser right at the end, before the credits rolled.
(The dirt on his coffin started to levitate. ) it was like a split second.
Literally, blink, and you miss it.
