Aron the Rogue Watcher (also known as Aron) is a dangerous alien supervillain from Marvel comics and an enemy of the Fantastic Four.
Aron was a member of the Watchers, powerful beings sworn to observe the universe but never interfere. Aron disagreed with this philosophy and broke away from his people as a dangerous heretic. The other Watchers tried to bring him to trial to manipulate the Fantastic Four.
The Rackcat pursues them persistently and Aron continues to observe out of fascination. Embracing a life of manipulation Aron travelled to Earth to begin his schemes and would also begin to spark a civil war against his own people. Eventually Aron's evil machinations were put to a stop by the Fantastic Four.
