The Boys creator Eric Kripke has a thing for the number five. He recently announced on X (formerly Twitter) that the hit Prime Video show will make its bow on their fifth season.

This announcement came ahead of the season four premiere on June 13, where we can see Jeffrey Dean Morgan join the cast with Homelander (Antony Starr) taking things to a whole new level.

Kripke wrote, “#TheBoys Season 4 Premiere Week is a good time to announce: Season 5 will be the Final Season! Always my plan, I just had to be cagey till I got the final OK from Vought. Thrilled to bring the story to a gory, epic, moist climax. Watch Season 4 in 2 DAYS, cause the end has begun!”

The post also had a heavily redacted script with the title Assassination Run. At the bottom of the script are the words, “See you for our final season, motherf***ers!”

He told Entertainment Weekly, “I'm excited to finally execute a 5-season plan. That's very exciting for me.”

The producer-writer referenced his plan to only have five seasons for Supernatural. It ended up with 15, 10 more than his original plan.

But why five?

“Part of it is such a wonky stupid screenwriter thing but three and five are the big magical numbers for writing. Three is movie acts, TV acts are five. Jokes are a runner of three for five. Five just seems like a good round number. It's enough to tell the story but also bring it to a climax without wearing out its welcome. It's been hard because I haven't been able to tell everyone. I was thrilled to finally be able to get the word out there,” he told the entertainment magazine.

And The Boys' upcoming fourth season will definitely feel like it's gearing up for a finale.

“That was part of my argument,” Kripke insisted.

“No one can watch this season without feeling at the end like ‘It's ending next year right?' So we might as well announce it so people can watch it with that cool epic heading-toward-the-end feeling, which is what I'm hoping for,” he continued.

However, just because The Boys is about to end, it doesn't mean its universe will as well.

“This story of The Boys will not continue on,” the writer explained.

“With any luck, Gen V will continue on, there will be hopefully a couple others in development that we're talking about that can continue on, but The Boys story ends in season 5,” Kripke added.

In a separate interview with Variety, he said that production for season five of The Boys will start in the middle of November which means that shooting will most likely go into the middle of 2025. The producer also spoke about adding A-list guests, and Supernatural fans might see an on-screen Winchester reunion of Jared Padalecki and Jensen Ackles (Soldier Boy).

As for the planned spinoff The Boys Mexico, Kripke said they're not ready to announce details just yet.
