Main characters
Tin Goyenda is the tale of three teenager detectives. They are investigators and adventurers.

The three teen friends, Kishore Pasha, Musa Aman and Robin Milford formed the Tin Goyenda. Sometimes Georgina Parker (more commonly referred to as Jina) with her pet dog Rafi accompany them.

Kishore Pasha
Kishore Pasha, a Bangladeshi-American, is the leader of Tin Goyenda (Goyenda Prodhan). His parents died in a car accident when he was 7. It was described in the first part that the accident occurred when they were returning home from Hollywood. In the original 'The Three Investigators' series however, the character Kishore's name is 'Jupiter Jones' and nickname 'Jupe'. According to the cover pages of the original series Jupe was a 13–14 year-old white American with black hair. His father and mother were both professional ballroom dancers and died in a car accident when Jupe was 4 years old.

Kishore's father's name was Zahed Pasha. He is shown living with his uncle Rashed Pasha and aunt Maria Pasha. Mr. Pasha owns a junkyard known as Pasha Salvage Yard. Kishore is a born actor, an electronic wizard and the locomotive of the Tin Goyenda as well. He was a child actor.

He has two dogs named 'Titu' and 'Bagha'. Obese in childhood, he maintains a strict diet. He has no interest in girls and is quite shy. He does not like to draw attention from public and likes to work behind the scenes. He has a habit of biting his lower lip when in deep thought.

Bearing an athletic figure and great strength, he is the team muscle. Often he uses his head as a weapon to headbutt the belly of the enemy, especially to clear his way. Musa Aman can fight any living thing, but he is scared of ghosts. When excited, he sometimes utters the word 'Khaichhe' () (though literally meaning eaten, here it means 'Damn it!'). Often he provides the comic relief. Musa lives with his parents: Rafat Aman, special-effect technician in a film-producing company. Musa hates to read books. He has a great passion for animals. Insects and soldier ants are attracted to him for some special element in his blood. Occasionally, he argues with the female character Jina. He has a younger cousin named Fariha. Loyalty to the team, deep respect for the teammates and occasional heroism: these qualities set Musa apart from other characters. He has faced life-threatening risks many times for helping others, including a time when he climbed a burning house to save a little boy.

Robin Milford
The ancestors of Robin Milford came to America from Ireland (In the original series- Robert Andrews, nickname Bob. According to the cover pages of the original series he is a 13–14 years old white American with golden hair). He is a nerd/ bookworm (although Kishore also reads). He is also known as the 'moving encyclopedia', he is the researcher and documentation specialist. He works part-time in the Rocky Beach Library and the leading local music company. He collects information related to their cases. The first book shows him as a skinny and short boy, but he grows taller. Like Musa Aman, he lives with his journalist parents. His father Roger Milford works for 'Los Angeles Times'. Robin is seen as an expert mountain climber, though it is mentioned that he broke his limbs several times when climbing mountains.

Sources
Most of the books were adaptations, mostly from western writers. This lack of originality was criticized.

It was initially based on The Three Investigators. Later books were based on other western detective juvenile thrillers.

 Authors 
The first 40-45 stories are from Robert Arthur, Jr's The Three Investigators. These stories have David Christopher on them.

Original 'The Three Investigators (1964-1987)' series published by Random House (world's largest general-interest trade book publisher) in English had 43 books written by Robert Arthur (10 books), William Arden whose original name was Michael Collins (13 books), Nick West (2 books), M. V. Carey or Mary Virginia Carey (15 books) and Marc Brandel (3 books). Two movies in English were made by a German-South African production house. The first movie was ‘The Three Investigators and the Secret of Skeleton Island (2007)’ and then ‘The Three Investigators and the Secret of Terror Castle (2009)’. These two movie plots were slightly different than the books and the updated story included technologies like GPS and mobile phones.

11 books became the next series called 'The Three Investigators Crime Busters (1989-1990)'. Two of these books were written by original series writers, one by William Arden and another one by Marc Brandel. Other writers of the ‘Crime Busters’ series were Megan Stine and H. William Stine, G.H. Stone, William MacCay and Peter Lerangis.

The stories which have Georgina Parker or Gina for short on them are from British author Enid Blyton's The Famous Five (1942-1963). She wrote 21 books. Television series were made in 1977 and again in 1995. The name Gina and eventually her full characteristics were based on the series. Other characters were transformed into Tin Goyenda by Hasan.

The Famous Five series included two brothers and a sister whose cousin was ‘Georgina Kirrin’. These characters were transformed into the characters of Kishore, Musa & Robin. Their cousin Georgina had the dog named ‘Timmy’ which was called ‘Ruffian or Rafi’ in the ‘Tin Goenda’ series. And though original ‘The Three Investigators’ series were American stories based around Rocky Beach, California, Los Angeles. The original ‘Famous Five’ stories were British stories.

'Goenda Raju' series was translated from or based on 'Famous Five' series. There the Characters were Raju, Opu, Babli & Misha, three siblings and one cousin. The Goenda Raju series stories were all converted into ‘Tin Gonda’ books. Therefore, all of the 'Famous Five' series books appear in the Bengali Tin Goenda series.

In stories of Greenhills (a village) the three detectives are much younger and solve small cases (most of the time the police help them). In these stories Musa, Robin and Fariha (Musa's cousin) live in Greenhills. Kishore lives in Rocky Beach and has a dog named Titu. These stories are from The Five Find-Outers, another juvenile series by Enid Blyton. The first story of The Five Find-Outers,The mystery of the Burnt Cottage was adopted into Jhamela.

Like the stories from The Five Find-Outers, some other stories are based Greenhills. These stories have seven members on the team. These stories are adopted from Enid Blyton's fictional series The Secret Seven. The difference between these stories and the originals are: in these stories Kishore lives in Greenhills and they form a detective group named Lodhosh that prefers Rohossho Vedi Dol in Bengali. The seven members are: Kishore, Musa, Robin, Misha (Kishore's cousin), Anita, Doly and Bob. These stories also feature Bably, a cousin of Musa and Nina (Bably's friend) who always interrupt in their case.

Stories with Dick Curter (known as Uncle Dick) are adopted from Enid Blyton's juvenile series The Adventure Series.

Enid Blyton's other series named The Faraway Tree was adopted into some Tin Goyenda'' books. Shamsuddin Nawab wrote some short stories based on this series' first novel The Enchanted Wood, leaving some magical creatures from the original novel out from the adopted one. However, these books were highly criticized by Tin Goyenda fans.

Christopher Pike's Spooksville series of 24 books were adopted into 24 Tin Goyenda horror stories. These stories include Roda and the stories are based in Death City, Roda's hometown. On the first story Rashed Pasha buys a house in the city and in the sequels Tin Goyenda often vacation there. The city is full of mystery and the paranormal. These stories feature another character named Tom, the friendly and knowledgeable homeless ex-mayor of Death City and a town witch. Christopher Pike's books are young adult fiction, horror and vampire stories as well. Pike wrote 75 books from 1985 to 2007.

Hasan drew others stories from other juvenile English series. The most notable one is The Hardy Boys. Romhorshok or Reza-Shuza book series’ made the boys a little older than in the original The Three Investigators series and they participated in seemingly more dangerous missions. Romhorshok’ series books were later converted into Tin Goyenda books, so Bengali Tin Goenda series has Hardy Boys stories in it. From 1927 to 2014, 489 books were published in the ‘Hardy Boys’ books series.
 
Hasan also adapted Tipu Kibria's Kishore Horror series, but this ended due to less popularity. After writing for more than a decade, Hasan departed from Sheba Prokashoni and Shamsuddin Nawab took up the writing. In August 2015, on the occasion of Tin Goyenda's 30 year anniversary, it was revealed in Kishor Alo (a monthly youngsters' magazine), that Shamsuddin Nawab is actually Qazi Shahnur Hossain; who is Qazi Anwar Hussain's son.
