I would say "What were they thinking," but honestly I don't blame them. Ganon is one sexy best.

...seriously though. This is what happens when your dev team is a boys club.

I made this joke about Ganon's forehead "horn" on the Reddit-based Tears of the Kingdom Discord server, and I almost got kicked off when I had to explain to a bunch of (presumably boys?) why a dildo would be shaped like that. That sure was an experience.
