With several other super hits in the year like Abhilasha apart from Khaidi, Chiranjeevi appeared to be an obvious choice for this position. Indeed, he would occupy this position within the next few years and, as even his competitors agree, he remained there for more than two decades. (Leading Telugu Actor Venkatesh said in an Interview to India Today that Chiranjeevi has been the undisputed No. 1 since 1987) Chiranjeevi continued to enjoy commercial success in the following years with hits like Challenge,Rustum and Jwala.

However, the ‘85 released film Adavi Donga was another important movie in his career in that it marked the beginning of his association with another senior director K Raghavendra Rao. Chiranjeevi acted in his direction for most number of films, after A Kodanda Rami Reddy. In '87 release Pasivadi Pranam, Chiranjeevi introduced Break Dance to Indian Cinema, a dance that drove his fans into craziness. While the industry obsessed with break dance for several years, the film has increased his market value hugely. By this time an already number one in the Telugu cinema, Chiranjeevi cemented his place as the undisputed king of Indian box office with super hits like Yamudiki Mogudu, Marana Mrudangam in 1988, and State Rowdi, Attaku Yamudu Ammayiki Mogudu in 1989. During this period, he was promoted with what is now a popular title “Megastar” in his movies, replacing his old title Supreme Hero. Chiranjeevi’s mass following continued to grow bigger and bigger with each passing year and so did his remuneration.

His several films were dubbed and remade in Tamil and Hindi. He starred in Aaj Ka Goondaraja Hindi remake of his Gangleader. He also acted in Telugu remakes of Tamil films including Mannan, remade as Gharana Mogudu in Telugu and remade from Telugu as Laadla (with Anil Kapoor in the lead).
