Eventually he escaped Halkan's den with a kidnapped girl Sonu. Suraj's life took a turn for the better when he met Adrak Chacha (Hindi word for paternal uncle) and his brothers. Initially he used to practice in his gym hiding from others. Seeing his devotion, Adrak allowed the child to make use of his gym (Lion Gym) for weightlifting helping him to build his muscle mass. He was also given training in martial arts under Haldi Khan (one of Adrak's brothers), boxing under Dhania Khan, marksmanshipuand Fighter Pilotnder Kalimirchi Khan (the youngest brother).
Suraj became Doga because of a personal tragedy that befell his "family" sometime later. A former member of the gym, Killota, set up his own place, and tried to eliminate his rivals permanently. Suraj was the only survivor of a carnage perpetrated by hired goons.
To seek revenge, Suraj adopted the alter ego of Doga, wearing a dog mask to hide his identity. He killed Killota's gang and further set out to become a oneman army against organized crime, mainly in Mumbai.
After that he killed Daku Halkan Singh who had by then become Minister Halkat. Because of his oneman army and brave image the people of Mumbai call him 'Mumbai ka Baap'(Daddy of Mumbai).
Doga has no super powers and only has the ability to communicate with dogs in order to gather information. He solely relies on his combat skills, especially in martial arts and boxing, and his remarkable physical strength and stamina, which is gained through years of hard work in his uncle`s gym. Doga has a bold and valourous personality and takes the aid of various weapons and guns. Moreover, he has a strong willpower and can tolerate any amounts of pain. One of his notable characteristic is his hatred for criminals and crime. Doga has a "show no mercy" attitude towards criminals and is popularly known as one man army. He lurks through the sewers of Mumbai in his hunt for criminals.
The name has been taken from the four institutions headed by his four uncles. Namely Lion's Den, Lion Occult, Lion Gym, Lion Aim Club. As Lion's (D)en, Lion (O)ccult, Lion (G)ym and Lion (A)im. Most appropriately classified as a vigilante superhero, Doga wears a hound like mask and inflicts terror in the minds of criminals by his generally destructive modus operandi. Doga likes to take out criminals with force which is sometimes excessive but that's what makes him exciting. Often we see Doga being assisted by his uncles, most prominently by Kalimirch who is an expert marksman. Doga also has strong relevance to his homecity Mumbai. The city of Mumbai has deep impact on the character development of Doga and the storyline. The corruption amongst cops, political murders, terrorist attacks, underworld crime etc. play a very vital role in the setting and surroundings of Doga. Many of Doga's feats involve taking advantage of Suraj's excellent knowledge of the landscape of Mumbai and the urban scenarios.
The name Doga is a derivative of dog, a creature which is extremely brave. Dogs are also scary and are usually kept for protection. These elements of a dogs nature are fairly prominent in the character of Doga.
