Ninjago, Season 13: Master of the Mountain

Skull Sorcerer:
Your cause is lost! Have the grace to admit defeat!

[He repeatedly blasts Cole. Cole starts to have a flashback of his mother]

Lilly:
I want you to promise me, Cole, that you will always stand up to those who are cruel and unjust. Always.

Cole:
Always.

[End flashback, return to present]

Cole:
It was her.

Skull Sorcerer:
What?

Cole:
It wasn't the blades.

Skull Sorcerer:
I told you that!

Cole:
It was her. The power inside my mother, it was the Spinjitzu Burst. It was all her.

Skull Sorcerer:
Alas, you're not half the warrior your mother was.

Cole:
Maybe not, but I am her son. And I made her a promise, to stand up to tyrants like you. Always!
