Ego (usually mega stars don't likely work with each other box of self ego and can't share a superhero screen with each other)

Budget (when u are making a superhero movie there first thing u take is best VFX and graphics but most of the budget usually goes to the mega star which was castes for eg: bellbottom total budget was 70 crore and the star cast was akshay kumer .he charge about 30to35 crore for the movie which is half of production budget )

Small actors (as I said most of the movie budget goes to the stars acted. But when a small star casted in a superhero movie it usually became flop boz of lack of popular between audience .movies like bhavish Joshi is basically a indian Kick ass but lack of popular of the actor it's a massive disaster.

Story and character development (usually in 90s most of the super hero movies was made but most are copied from Hollywood for eg: superman india 1987.A total copy of dc character superman. No original story line and not a proper characters of movie.not only the Tollywood movie superman staring n.t.rama.)

Lack of communication with audience (there are may hit franchise of superhero in india like shaktiman &Krrish but both fail. Due to lack of usuall appearance.where skatiman was a bit franchise but it's limited on tv only. Where Krrish apper after 7to8 years after its origin. Most it's a hit movie. But most of it story revolves around one character.

Lack of comic (where most people will defend with marvel have a hit comics so it's easy for them. But india also have many hit character like nagraj,bhokal,chakra, inspector steel.they why we are lack of movies , it's usually boz indian audience don't respond superhero movies when a mega star casted. But it usually don't seen in Hollywood the first mcu movie was Ironman which have a budget of 14crore and at that time rdj was not a big star. And besides mcu and dc other superhero movie like Hellboy and Hancock was also a hit during its time. So it not about a hit comics )

At last we should consider superhero movies even it doesn't have a mega star

In my suggestion i say movies like 1. Mard ko dard nahi hota 2.bhavesh joshib 3.toofan 1989
