I wondered - could AI go tarder? here is the result:

Hello, this is Copilot. I can try to flesh out the synopsis into a plot summary with actual Fantastic Four characters, based on the selected text from the web page. Here is my attempt:

• Origin and Discovery: The Fantastic Four (Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm) are a team of scientists and adventurers who gain superpowers after being exposed to cosmic rays during a space mission. They learn to use their abilities and become public heroes, attracting the attention of other Marvel characters such as Spider-Man, Black Panther, and Nick Fury.
• Mystery and Suspense: The Fantastic Four also notice a series of strange break-ins at various locations, such as a military base, a museum, and a bank. The culprits are seemingly ordinary people with no connection to each other, but they all have a small clay figure in their possession. Reed deduces that someone is using mind control to manipulate them, and traces the source to a sculptor named Phillip Masters, who is the father of Alicia Masters, a blind artist and Ben's love interest.
• Conflict and Betrayal: Reed confronts Phillip, who reveals himself to be the Puppet Master, a villain who can control anyone he makes a clay replica of. He has been using his power to steal valuable items and information, as well as to test the limits of the Fantastic Four. He also reveals that he has made puppets of the entire team, and activates them to turn them against each other. Ben, who has been spending time with Alicia, is the first to fall under his control, and attacks Reed, Sue, and Johnny at the Baxter Building, their headquarters.
• Resolution and Showdown: The other three manage to escape and track down Ben and Alicia, who are held captive by Phillip at his workshop. They free Ben from his influence and confront Phillip, who unleashes his army of puppets, including some of the Marvel cameos from earlier. A chaotic battle ensues, with the Fantastic Four fighting their friends and foes alike. Reed manages to reach Phillip and destroy his puppet-making device, breaking his control over everyone. Phillip is arrested and taken away by S.H.I.E.L.D., while the Fantastic Four and their allies celebrate their victory. The movie ends with a hint of a bigger threat looming in the horizon, as a silver figure flies across the sky.
