Ever since the Sons of Garmadon had found Wu as a baby. He was locked up all alone in a room. Wrapped inside a blanket and put in a crib.

A blanket was on top of him.. what reason? No idea.. probably to silence him. As he lay there...in that cold room. It's terrifying as a baby, with no way to protect himself, being surrounded by villains.

And worst of all.. he had no memory.
