*Misako (nicknamed Koko by Garmadon) is Lloyd's mother, Lord Garmadon's ex-wife, and Master Wu's ex-sister-in-law. She is also the famous ninja known as the Lady Iron Dragon.

Misako met Garmadon in the Battle of Nine Armies under the identity of the Lady Iron Dragon. At one point, Garmadon gave her the nickname, "Koko." When Lloyd was born, she left Garmadon and went to Ninjago City in order to raise Lloyd on her own because she didn't want him to grow up to be a warlord like his father. Koko raised Lloyd in Ninjago his entire life and made sacrifices to help him fit in around their surroundings. She did her best to convince Lloyd to not be ashamed of who his father was. Her life in Ninjago seemed to be difficult due to the citizens' hatred for her son and even though she did manage to have a best friend, her friend made it clear to Koko that she didn't want Lloyd to play with her own child.

Unlike her TV series counterpart, Koko is much younger in comparison, having orange hair, wearing orange lipstick, and is mostly clad in clothing similar to Claire's. She is also shown to wear brown pants, rather than the blue one Claire has.

As the Lady Iron Dragon, She wears a black battle armor, wears a crown on her head, and has a unique armor that has a quiver attach to it.

She has the most dramatic changes from her TV series counterpart out of the redesigns. She appears to be much younger, with orange hair (in contrast to her TV counterpart's brown hair in her youth) and the absence of glasses. She is also oblivious to her son's identity as the Green Ninja, in contrast to her TV counterpart being the first person to have known of Lloyd's destiny of being the Green Ninja. Unlike her show counterpart, she doesn't seem to have feelings for her (ex) husband's younger brother, Wu.

As Lord Garmadon's ex-wife, she is not afraid to stand up to him – even though he's twice her size and has twice as many arms. Koko knew "Garm" when he was a young warlord eager to conquer the world. Back then, she thought that was just a figure of speech. Turns out, he meant it. So she took young Lloyd away in the hope of giving him a normal life. But that didn't work out quite the way she planned.*
