Fun

If you wanted to be recruited, you could just wipe everyone's minds and join later. With a grin, you walk through a wall and head downstairs, thinking about who you'd start with. Quite a lot of the Avengers were...attractive, to say the least. Wasp, Scarlet Witch, Spider-Woman, Miss - oh, Captain now isn't it? - Marvel, Black Widow...
Or maybe you should visit the X-Men, or sneak into the Baxter Building and steal away Susan Storm. Any of those options were possible - you were timeless now, after all.
