He be bad dad. The baddest. In live action, he was so bad he forgot to put sunscreen on salt son and salt son got a sunburn *gaso*

He still has said sunburn to this day and Father lord still dont feel shame

What a bad dad

He likes wiping entire cultures out and sailing his ship right over frozen Avatars.

He also likes doing overdramatic evil announcments and sending his daughter to kill salt son because he's too stupid to do it himself

he be the pheonix lord so he'll be reborn when he dies oh no is he one of the korra villians secretly *gaso* i bet he is
