|“The entire wing was built for one purpose... to hold the rottenest egg of all.”|
|— Warden Noble to Lloyd about cell one|
Cell one is the most heavily protected cell wing in Kryptarium Prison.
Shortly after Lloyd defeated Garmadon, he was placed in Cell One in order to prevent him from escaping. When the Oni attacked, Lloyd and the Ninja released Garmadon out of the cell, making Aspheera finding her way into the cell after a long battle at the monastery.
- Cell One is very similar to the cell in the Crystal Cove Animal Asylum for the Criminally Insane where Professor Pericles was locked in.
