- Kakababu: Kakababu is the disabled former Director of the Archaeological Survey of India, whose real name is Raja Roychowdhury. He is from a migrated Bengali family. His family origin was from East Bengal. In one of the earlier stories, it is said that Kakababu lost one leg in a jeep accident in Afghanistan, several years ago, and walks with the help of a crutch. However, in "Kakababur Prothom Abhijan", it is revealed that Kakababu lost his leg when he jumped off a cliff to help his friend Kamal. This accident however has not crippled his strong mental will and physical strength. He is much sought after by the Indian intelligence to solve critical cases of crime. He has worked in CBI for some years as an advisor. He has been trapped and captured by enemies on several occasions, but escaped unhurt, or nominally hurt. In solving cases of crime, he has traveled to several parts of India and the world. Each new adventure takes him to a new destination. He is excellent in fencing, revolver shooting, and swimming. His age is estimated to be over 60 at present. On a few occasions, he used the crutch as a weapon.

He has also been trapped on several occasions by ruthless enemies. He is an excellent swimmer and an outstanding athlete. He is the best friend of Jojo.
- Jojo: Real name is Rajat Bhattacharya (as mentioned in "Santu o Ek Tukro Chaand") The best friend of Shantu and equals his age and they both studied in Presidency College. He was very close to Kakababu like Shantu and Jojo also loves him a lot. He was introduced as a character to give comic relief, resulting from his habit of telling lies but not for bad will, but creating imaginary stories about his dramatic life experiences with his astrologer father.
- Biman Banerjee: A pilot of Air India, neighbour of Kakababu and Sontu. He got involved in some of Kakababu's adventures like Khali Jahajer Rahasya, Kakababu Here Gelen? etc.
