20 Insane MCU Moments Marvel Didn't Show
7. Cap Teams Up With Red Skull (Avengers: Endgame)
Stephen Freely and Christopher Markus wrote every idea possible for Avengers: Endgame and tried to stuff as much as they could into the film. Freely and Markus had many contentious discussions on where each Avenger would go during the time-heist. In the end, they decided Black Widow and Hawkeye would head to Vormir to collect the Soul Stone, which is guarded by the Red Skull. Since this relic can only be obtained with a sacrifice of love, Black Widow kills herself.
This may be one of the most powerful moments in the film but Freely and Markus originally had Captain America heading to Vormir. Since Cap is the only character to have history with the Red Skull, it would have been amazing to see two bitter enemies forced to ally against a common foe.
It's frustrating that we never saw this confrontation, moreso because we know for a fact they crossed paths when Cap returned the Stones back to their original places. It would have been funny (and awkward) to see how Cap reacted when he learned the Soul Stone was in possession of his arch-enemy.
