Cyclops and Emma Frost may not be a couple, but that isn't stopping them for working together for the betterment of mutantkind. And as December's cover to X-Men #3 shows us, they can also put their differences aside to spend some quality time atop a dinosaur.

ComicBook.com revealed the cover by artist Leinil Yu, and it shows the former lovers on top of a dinosaur in the Savage Land. Yu's cover for X-Men #4 puts Storm and Armor in the spotlight, as the two women prepare for battle.
