In other words, they have qualities of both Brahmin and Rakshasa.

In popular culture
In 2014, Vikram Bhatt made India's first 3D creature horror film entitled Creature 3D in which the creature or demon is a Brahmarakshas - a mutant from Indian mythology. However, his demon, who is a Brahma Rakshas, will not be a copy of its ancient idol in order to avoid hurting any religious sentiments. Due to this, Vikram Bhatt came up with his own imaginative take on the creature by using special effects in this film. In the film the Brahmarakshasha is depicted as a 10-feet tall animal like creature, which has a swishing tail, carnivorous teeth and nails. It is in the same league as the Yeti. In July 2016, Zee TV announced the weekly horror based television series titled Brahmarakshasha—the story of a resurrected Satan.
