VIDEO : Captain Marvel Was To Debut In 'Avengers: Age of Ultron'

Comicbook.com reports 'Captain Marvel' is hitting theaters soon, but Carol Danvers' MCU debut was originally very different!

Captain Marvel almost appeared in Avengers: Age of Ultron in the post-credits scene.

[Captain Marvel] was in a draft. But to me, it would have done that character a disservice, to meet her fully formed... when 99% of the audience would go, ?Who is that??

So Thanos was chosen for the stinger instead, as his appearance served the plot of the franchise much better.

Captain Marvel hits theaters March 8th.
