Power is not given. It must be taken – The Godfather III
His Father's Son is a oneshot about Zuko from Avatar: The Last Airbender learning to rule the Fire Nation. Some of the plotline might seem familiar, but it was actually written long before the comics were released.
Excerpt
His Father's Son
The global community was in an uproar when not only did Zuko not attend the next council meeting; his representative also announced the cessation of all aid to the Earth Kingdom as long as its current ruler was in power. Failure to comply would result in permanent cessation of aid.
Aang was the first to call on Zuko…and the first to be turned away.
Mai blinked as she watched the Avatar stomp off in a huff from her balcony,
"Was it wise to do that? He is the most powerful being on the planet."
"Power?" Came Zuko's snide reply, "He was born with his power. He didn't earn it." He held her from behind, arms snaking around her waist,
"I was given power when they put this crown on my head, but it wasn't real. I had to take my power." He bent down to kiss her neck, "Thank you."
"For what?"
"For being here. For being with me."
Eyes hinting at something a little more…exciting, Mai pulled off his royal crown, letting his hair flow free, "Well…I know something we could do…together…"
"Oh really?"
"Yeah. Really."
"Lord Zuko! The special prisoner wishes to speak with you!"
