Morgan Le Fay has used the Twilight Sword and the kidnapped Scarlet Witch's powers to transform the modern world into her own medieval playground:
Let's watch George Perez and company give us Arthurian versions of 30+ Avengers, shall we?

Gosh I love comics.
Still, Morgan Le Fay, Kulan Gath, etc...why do all of these villains want to turn modern-day into a copy of their home time periods? You'd think that constantly getting their ass kicked back then would make them less nostalgic for home. Plus, indoor plumbing, right?
All I know is, if I were to wake up in say the 26th century and somehow had ultimate power, the last thing I would do is transform everything into an ersatz late20th/early 21th century cosplay fest. But maybe that just proves that I'm not sufficiently evil...
