As the first generation was more like RAMAYAN
The third reminds me of Mahabarat:
Where MANTHAN is like Durodhan
NAKUL is like BHIM
Lakshya is offcourse KRISHNA
Eklavya probably would be like Yudisther at beginning BEFORE HE BECOMES THE MAIN VILLIAN AGAIN. Like his father.
Karan- Nandini son- my money is on that he will b like ARJUN.
