Stop using Quicksilver in X-Men film or prohibiting use of name by Marvel.
Quicksilver and The Scarlet Witch belong in the Avengers Universe far more than the X-Men Universe. Their history in the Avengers is far more extensive and their characters have played pivotal roles in many of the Avengers story lines. If the new X-Men film needs a speedster for a key sequence they can always use Northstar. This move by 20th Century Fox smaks of pettiness and comic book fandom should consider strongly boycotting the new X-Men film as a response.
