The Avengers have disassembled! Due to injuries, treachery, and villainous time travelers; Earth's Mightiest Heroes are now defunct (on the east coast). What a sad day for the legions of Avengers fans! However just because the heroes are gone, that doesn't mean evil takes a vacation! And when crazy things start happening in New York City, one avenger (or pseudo-avenger) answers the call…Edwin Jarvis!
