I honestly think the YRF Spy Universe had the potential to become something really special, but they focused too much on making every movie bigger instead of making every character unique. 

A cinematic universe shouldn't just be about crossing over actors, it should be about crossing over characters that are so different from each other that you genuinely can't wait to see them interact. Right now, if you really think about it, Tiger, Pathaan and Kabir all end up feeling like different versions of the same elite spy. They're all incredibly skilled, all have the same end goal of saving the country and most of their personality comes from one-liners and action scenes. The differences are there on paper, but they rarely feel meaningful.

Tiger is actually the one character I wouldn't change much. He's the old-school field agent who's been through everything and values relationships over blind duty. He already has a clear identity. Also can't give much charector to salman khan he would still be salman khan 

Pathaan is where I'd make the biggest changes. The movie briefly hinted that he wasn't in his physical prime anymore, but then immediately forgot about it. I'd fully commit to that idea. Make him older, heavily injured and no longer the best fighter. Instead of punching his way through every problem, make him the smartest guy in the room. A genius inventor who builds gadgets, explosives and crazy plans to solve impossible missions.

The story should have focused with him making a unit made up of physically broken agents that everyone else has written off. People with prosthetics, old injuries or disabilities who are considered "finished" by the system. They're the team that gets sent on missions nobody else wants because, in the eyes of the agency, they're already expendable. That immediately gives Pathaan a completely different role in the universe.

Even his missions would be different and interesting in each sequel 

Kabir is probably the biggest missed opportunity for me. The relationship between him and Khalid should've been the entire focus of the first movie instead of something rushed for the dumbest twist ever. 

Spend the whole film showing Khalid trying to earn Kabir's trust through training and missions because Kabir killed his father and can never fully trust him. Slowly build that mentor-student relationship until they genuinely feel like family. Then end the movie with them finally trusting each other, but suddenly kabir is the one turning traitor.

The next film is where everything falls apart. It is revealed Kabir uncovered a shadow organisation operating inside Indian intelligence and goes rogue, forcing Khalid to hunt down the one man he respects the most. It would be chase movie with kabir trying to uncover the shadow organisation while khalid is chasing him

They can end the trilogy when they defeat it but the main focus would be to show a side of being a spy that is on the run kinda like winter Soldier but keeping the emotional focus the khalid and kabir relationship centered around trust and loyalty 

Alpha is the one I'd completely reinvent. I wouldn't even make her a spy. I'd make her an assassin who was kidnapped as a child and raised in labs to become the perfect weapon. She has no social life, no friends, no understanding of what a normal childhood even looks like. Her entire existence revolves around getting the approval of the man who raised her, even though he only sees her as proof that his experiment worked.

Like that was the most interesting part of it but they didn't even give it a minute to explore and creating charector that we would love to see interact than just actors in each others movies

There are many such concepts that the universe introduces but then nose dives into stupid 80s cliche of plastic surgery twin sisters separated at birth etc

What Spy Universe Could have been
