Jay Walker and Lloyd Garmadon

You're Jay's younger sister. Unlike him, your power isn't just electricity… it's pure energy, which sometimes makes it harder to control. When you were little, you avoided using your abilities for fear of losing control, but everything changed when you had to save Jay on a mission.
From that day on, you joined the ninja team. You have a calmer personality than your brother, but when you fight… you are unstoppable.
Relationship with Jay:
They're always teasing each other, but they ALWAYS protect one another. He tries to teach you to control your powers… although sometimes you end up saving him.

—“Jay, calm down,” —you said.
—“No. I’m watching them.”
He went away.
And as soon as it disappeared…
