Zuko vs Azula

Zuko vs Azula
Fiery siblings fighting to rule
Zuko is banished, Azula a tool
To regain honor Zuko must
capture the Avatar and gain Ozai's trust
Azula won't stop till she stops him for good
She wants to end their siblinghood
Forever, the two together shall clash
And in the distance fire and lightning crash
The winner of this is truly unknown
It all depends on fate alone.
