Marvel Studios has officially released the third Avengers: Doomsday teaser trailer, and this time, the spotlight is put squarely on the X-Men.

Professor X (Patrick Stewart), Magneto (Ian McKellen), and Cyclops (James Marsden) are featured in the preview, which paints the picture of yet another bleak future for the mutant team. The X-Mansion is in ruins, and Scott Summers appears to be the last one standing against the massive Sentinels.

"Death comes for us all, that’s all I know for sure," Magneto can be heard saying. "The question isn’t are you prepared to die, the question is who would you be when you close your eyes?"

The fourth teaser leaked online earlier today, featuring Black Panther, King M'Baku, Namor, and The Thing. According to @MyTimeToShineH, despite talk of fifth and sixth sneak peeks being on the way, only four are being sent to theaters. That means the final teaser will be officially released this time next week.

Fortunately, we won't have long to wait until seeing more from Avengers: Doomsday. Marvel Studios is expected to pull back the curtain on Doctor Doom in a traditional trailer that debuts during next month's Super Bowl.

Back to the X-Men, and love or hate 20th Century Fox's mutant franchise, it looks like the MCU has nailed these characters in what will likely be their final appearance before the post-Avengers: Secret Wars reboot helmed by Jake Schreier.
