Comic Book Threads Why make this the final season of 'What If'? To replace it with an Exiles series. What has worked really well for Marvel? The X-Men. What do the showrunners seem to really want? A team of variants visiting alternate takes of Marvel worlds and stories. With Exiles you can have a semi-consistent team and have then carry arcs across different worlds. The other Watchers in the trailer might EXILE the one we know and we're getting mutants.
