The teaser of Nandamuri Balakrishna's Ruler dropped today. The much-awaited 75-second video presents Balayya in two distinct looks — as a ruthless cop Dharma and in an uber-cool avatar resembling Tony Stark from the Avengers franchise. 

As expected, the teaser is packed with powerful dialogues, explosive action sequences, a fleeting glimpse of the female leads, a flashback episode, and a menacing villain. 

Balakrishna's thunderous dialogue, that goes: "Vantimeedha khakhi uniform untene bonelo pettina simham la untanu...uniform teesana...bayatakochina simham la aaganu...ika veta ee..."(I will be like a caged lion when I wear khakhi...if I take off my police uniform...like a lion freed from the cage, I don't stop hunting), is sure to win the hearts of Balayya fans.

Directed by KS Ravi Kumar, Ruler is slated for release on December 20. The film also features Sonal Chauhan, Vedhika, Prakash Raj and Bhumika Chawla in pivotal roles.
