Hedlok leaks
Gameplay footage of a battle against Hedlok was accidentally leaked before Nintendo had lifted the review embargo on ARMS.

A screenshot of a battle against Max Brass, the final boss of Grand Prix, was posted by the review site Stevivor before ARMS was released. It has since been taken down and replaced. Later, Nintendo Life referred to the final boss as Max Brass in an article.
