HR and ID quoted their respective challengers as arjun and karan of mahabharat . But in my view the role of krishna is played by HR and he was of opinion that finally arjun will win as it happened in the mahabharat story. No doubt karan was more powerful than arjun, so lord krishna played his trick by sending kunthi devi to karan to get the kavach and kundal of karan [that is the main protector of karan] so that arjun can win over karan. karan is son of surya putra. and surya is rised from east. [debo is also from east ] The so called HR of krishna played his trick to his level best to dislodge debo from the competition [yudh] by giving less marks , gave zero mark for humma humma song [for which ID gave chumma to debo] criticised him, debo bhikhnewala cheez nahi hai and what not. above all during judges round HR purposely gave him a song without putting debo for test and when debo sang the song which HR asked him to sing he was laughing mischievously at debo and gave ten marks as if he has given donation of full marks to debo. But real krishna of mahabharat realised the strength of karan but he was feeling sorry for karan to protect arjun. but kalyug krishna could not do any mischief to protect arjun [vinit] and ID prooved that karan's strength is more powerful bcos the choice was left to public and kalyug krishna could not do anything. that's how the kalyug mahabharat ended karan victory over arjun. This is kalyug mahabharat. [ID played a good role of appreciating every challenger who sang well and encouraged them but fired his challengers when they gave the excuse that gala kharab tha] He never tried to hype anybody as far as his gharana challengers are concerned but trained them well behind the scenes and left to public to give verdict.
finally one thing is to be mentioned that when nihira was out HR said that nihira ke saath koi nainsafi nahi hua hai,use public ne vote out kiya. is baath ko maanna badega. when the same thing happened with his arjun why he is not gracefully accepting verdict of the public.
