Who are the main characters in Ninja Kids Story?

Often, the main characters are the ninjas themselves. They could be young trainees starting their journey.

The main characters in the ninja turtle story are the four turtles - Leonardo, Donatello, Raphael, and Michelangelo, and their sensei Splinter, as well as the villain Shredder.

I'm not sure specifically, but there could be the Ninja Kid himself as the main character.

Most likely, the main character is the boy ninja himself. There could also be his ninja master who teaches him the ways of the ninja.

The main characters in a Teenage Mutant Ninja Turtles kids story are the four turtles - Leonardo, Donatello, Raphael, and Michelangelo. There's also their human friend April O'Neil. And of course, they often face off against various villains like the Shredder and the Foot Clan.

I don't know for sure, but it could be the ninja himself or herself as the main character. Maybe there are also some opponents like rival ninjas or samurais.

Ninja Hattori is definitely one of the main characters. And of course, his master Kenichi should be there too.

I'm not sure exactly, but likely there are some cute ninja girls as main characters.

The super ninja boy is the central figure. But there could be other characters like his best friend who is always by his side during his adventures. And perhaps an antagonist, an evil ninja or a powerful sorcerer who is trying to stop the super ninja boy from achieving his goals.

Perhaps the main characters are siblings. A brother and a sister who have to face some challenges together. The brother could be the more adventurous one, always getting into little troubles, while the sister is the smart one who figures out solutions. There might also be their pet dog that tags along in their adventures and plays an important role in the story.
