Ep 25. The Sentry Sinister

The Fantastic Four are back in action for episode 25 of the first season, titled "The Sentry Sinister." The episode begins with the team enjoying a well-deserved break at the Baxter Building. However, they quickly realize that their peace and quiet is about to be disrupted when a strange energy signal picks up on their radar.

Without hesitation, they spring into action to investigate the source of the signal, which leads them to a mysterious structure hidden deep in the heart of the city. As the team approaches the building, they are confronted by an army of robotic sentries that seem to have a single mission: to stop the Fantastic Four at all costs.

Undeterred, the team springs into action, using their powers to neutralize the sentries as they make their way deeper into the building. As they progress, they begin to notice that the structure seems to be more advanced than anything they've ever encountered before, with hidden corridors and secret labs hidden behind impenetrable walls.

As they continue their search, they encounter the mastermind behind the structure: The Sentry Sinister. This powerful and enigmatic villain seems to have an almost supernatural control over the technology that surrounds them, and the Fantastic Four quickly realize that they're in for a fight unlike any they've faced before.

With the Sentry Sinister's arsenal of weapons and gadgets at his disposal, the team struggles to keep up with his limitless power and relentless attacks. As they battle their way through the building, the team soon discovers that the Sentry Sinister has a personal grudge against them, and that he will stop at nothing to see them destroyed.

Despite the odds, the Fantastic Four refuse to back down, and they continue to push forward into the heart of the Sentry Sinister's lair. As they reach the final confrontation, they realize that the only way to defeat this villain is to work together and use every trick in their arsenal to bring him down.

With their combined powers and cunning, the Fantastic Four are able to overcome the Sentry Sinister and put an end to his reign of terror, but not before they learn a valuable lesson about the dangers of relying too much on technology. The episode concludes with the team returning to the Baxter Building, exhausted but victorious, ready for whatever the future may hold.
