"He practices what he preaches. I cannot comment on what separates him from his contemporaries but I believe he has his true identity and he is what he is," she said.
Lot of jokes are trending on Rajinikanth and Soundarya feels it is because he can do impossible things.
"There is a lot of undercurrent, of a lot of respect for every Rajinikanth joke. It is not that people come up with these things, it is because my father can do these impossible things, and I think only he can," she said.
Soundarya is making her directorial debut with 'Kochadaiiyaan' with her father in the lead.
It is a hi-tech 3D film with photorealistic motion capture technology, also called as performance capturing technology. Such technology was used in Hollywood films like 'Avatar', 'The Adventures of Tintin', etc. 'Kochadaiiyaan' will take 3D films a step further in India.
Since animation films haven't had a great run at the box-office, Soundarya feels Rajinikanth can be a game changer.
"I believe he will be the game changer because animation has not been understood in our country yet, as it is still considered cartoon. In our country, again because of the lack of budget, time and trained technicians, a lot of films have not done justice to what animation can do," she said.
"People in India still feel animation is Tom and Jerry. Yes, animation is Tom and Jerry but that's not it. Only he can change this myth that animation is not cartoon. I hope that my father will be and I am confident that if at all there is anybody who can break the myth that animation is not cartoon, it is only Mr Rajinikanth," she said.
Rajinikanth feels Soundarya has gone a step ahead with the kind of film she has made and is proud of her.
"He is proud that I dared to something different...He is very proud," she added.
