A full circle novel is a type of novel where the story comes back to its starting point in some way. For example, the plot might begin in a particular setting or with a certain character situation, and after all the events and developments, it returns to that same state or place. It gives a sense of closure and completion, as if the story has made a full journey.

A 'full circle story' is a narrative that comes back to its starting point in some way.

One of the best Fantastic Four stories is 'This Man, This Monster'. It delves deep into the concept of identity and how appearance doesn't define a person. It shows the Thing's struggle with his new form and the contrast with a character who desires to be like him. It's a classic that really explores the emotional depth of the characters.
It's tough to put a precise figure on it. The Fantastic Four franchise has a rich history of comic book releases. There are countless regular issues, spin-offs, and limited series. So, there could be thousands when you consider everything.
Certain variant covers or signed copies of Fantastic Four comics can be valuable. Issues that introduce important characters or have significant plot developments often command higher prices in the collector's market.
