Despite being a pretty major character in The Legend of Zelda: Echoes of Wisdom, Nulls identity remains somewhat of a mystery. Likely taking place on the Zelda timeline sometime before Skyward Sword, Echoes of Wisdom tells a story that, in many ways, subverts typical series tropes. This time, it’s Link who’s in trouble, and Zelda who has to save him with the help of the mysterious, otherworldly being Tri, and a staff that allows her to clone objects throughout the world.
