How can it be a spoiler if it's in the trailer?
Spoiler culture is just getting silly now.
Depends on how you define a spoiler, there have been trailers that LOTS of stuff.
Like from the Soylent green famous plot twist to the infamous BvS that tells the whole story to the classic Amazing spider man that shows the literal last frames of the movie
This is an info that have been kept from all the 2(maybe 3) usa trailers till now. It is a japanese trailer that is showing 2 seconds if the character.
