This idol was once originally called as Venkatatturaivar and stands for the anger aspect of the Lord. Apart from the Dhruva Bera, this is perhaps the earliest idol of the temple and in all probability this was used as a processional idol in the very early days. This is about 18″ high and stands on a pedestal of about 7″ height. The chakra of this image is slightly tilted. Sridevi and Bhudevi both are standing figures are seen. There are now three occasions of which Ugra Srinivasa alone figures, Uttana Ekadashi, MukkotiDwadasi and Dwadasaradhana. Legends have it that the rays of the sun should not touch this idol, and if they do, it would bring incalculable harm to the world.
Everyday after the morning tomalaseva, a darbar called Koluvu is held in the Tirumammni mantapam when the Deity is brought and is seated in a silver chair with a gold umbrella above him. This idol officiates for the main idol during this function. Hence his name is Koluvu Srinivasa. He is akin to the guardian deity and supervises the temple household, and keeps himself posted with all the affairs and revenues of the temple. The panchangam or the calendar of the day is also read out before him everyday. It is also here that the matradanam of rice, the customary share of the archakas, is made. Though this is known as Bali Bera, he has never been known to have been taken out and offered Bali after the daily pooja is over.
