Nagraj aur Super Commando Dhruv, Nagraj aur Bugaku, Kirigi Ka Kahar, Maine Mara Dhruv Ko, Chumba ka Chakravyuh, Doctor Virus, Khazana series - all were superhits at that time. Nagraj aur Bugaku still holds the record of max number of copies sold in RC history till date. I still got whole collection of Dhruv and Nagraj, and some of Fighter Toads, Bhokal, Parmanu, Doga, Bhediya, Pret Uncle but hardly get any time to read them.
Reason why Nagaraj has become so confusing is that there are 3 versions of him now - vishwarakshak, atankharta, narak nashak.
btw sorry for all the OTs. i think we should have a separate thread for RC fans
