Yuyutsu

He was the paternal half - sibling to Gandhari's children: Duryodhana and the rest of the 99 Kaurava brothers and their sister, Dushala.

[3] Yuyutsu is celebrated as a moral warrior who chose the path of righteousness, in spite of being born in circumstances that predisposed him to evil.

As the war was about to begin, Yudhishthira made an announcement in the battlefield, saying anybody who wishes to change sides can do it then, before conches are blown.

Additionally, Yuyutsu saved the life of Bhima by informing the Pandavas about Duryodhana's cunning schemes, which included poisoning water.

[7] When the Pandavas decided to retire from the world at the start of the Kali Yuga and departure of Krishna, Yudhishthira gave the charge of supervising the kingdom to Yuyutsu while Parikshit was made the king.
