Good question.
Nowadays, they don’t make movies like those made in the 90s anymore so we hardly see heros with friends.
But there was a name that came to my mind & it is Vikrant Massey, though of course he’s moved on to lead roles. But I loved a lot of the supporting characters he played.
Is it Aparshakti Khurrana coz he plays sidekick in most of his movies.
