When he and Sura were pups his mother Luri took in the Cub Mowgli after she saw him feeding like her own cubs. Then his father Alexander herd the fierce tiger, Shere Khan coming, and Alexander stood his ground to protect his family. Later, He spoke to Luri about adopting the man-cub, Which she reluctantly agrees to. Years later, He and Sura are full grown adult wolves.
In the episode "More Precious than the Law", Akru gets competitive with Sura which caused him to get himself hurt and break a jungle-law while hunting a buffalo, causing all the wolves accept his family to shun him and maybe even leave him for dead. Mowgli in particular strongly opposed to let him die as a punishment, and sets out to acquire a flower with healing properties, even if it means getting himself kicked out of the pack. Fortunately though Mowgli never does get banished, and was allowed to fix Akru, who gets forgiven for his behavior.
- He and Sura could be the anime's representation of Grey Brother, who's absent from the show.
