Mowgli, Baloo, and Bagheera (Disney's The Jungle Book) as Bran Stark, Hodor and Osha (Game of Thrones)
Bran and Mowgli both have a strong connection with animals. Bran is adventurous, brave, and loyal to his friends. Mowgli is a little more playful but shares the same adventurous nature and need to prove himself fearless.
Bagheera is caring and looks after Mowgli, like Osha cares for Bran. Osha is a wildling and Bagheera is literally a wild animal.
Baloo and Hodor, not really any similarities but both are big and carry the kid around on their back.
