Marvel Comics has sued NCSoft and Cryptic Studios, the makers of the popular MMORPG called City of Heros, because of what player might do.

Many speculate the reason for the lawsuit is that Marvel is making their own MMORPG game and fear that the established City of Heroes game will lower their market share.
