They might be from a different Earth, but The Fantastic Four know a thing or do about tradition. Not only does The Fantastic Four: First Steps include a mid-credits scene, but there's also a fun surprise if you wait all the way until the end. Like we mentioned, there is one mid-credit scene and another in the post-credits.

The "Doomsday" plot leak also seems to confirm the big fight at the X-Men mansion in the universe where Monica Rambeau ended up at the end of "The Marvels." That universe's anchor being is a Professor X (Patrick Stewart) variant that Doom wants to kill. Interestingly, Earth-616 and Earth-10005 -- where Monica is -- are on a collision course.

First Steps" has a thrilling ending that teases Dr. Doom and where the MCU goes from here in "Avengers: Doomsday."
