Mokuton Mecha
Naruto gazed impassively upon the massive form of Sukaku. The One Tailed Beast was massive, almost as tall as the Hokage Monument. As the group of ninja around him panicked, Naruto gathered chakra and channeled it to the ground. Roots came first, massive roots that seemed to cover the ground of the clearing. As Naruto kept on channeling the roots sprouted into two great trunks, each larger than a house. Where they touched the trees of the forest they absorbed them and they grew bigger and taller until they touched. They kept on growing and from the combined trunk came twin branches each the size of the Hokage Tower on opposite sides. Naruto, long since absorbed by the giant humanoid tree appeared on it's 'head'. And the giant took a stance and leaped.
It was a voice heard all the way to the capital, a tremendous bellow that froze everyone on their tracks. Everyone, from Genin to the battling Kages turned their head to the titan that was flying high above the ground. And a green-clad Jounin smiled with pride as his student controlled the very essence of Konoha and executed a perfect:
"KONOHA SENPUU!"
A/N: The First Hokage had a bloodline that affected entire battlefields. He is said to have created the forest for which Konoha is known with a single technique. Why do people give this amazing bloodline to Naruto and then have him NOT do crazy awesome things with it? Like, yes, wooden mecha to fight Tailed Beasts like they're Kaiju. It's not like Naruto lacks the chakra...
And if I ever read a Banishment fic where Naruto has the Mokuton I expect him to take the trees with him. Because he is a prankster and they totally deserve it. Man, I wish someone would do PerfectLionheart's challenge like this.
A/N2: I wrote a Tree Walking chapter for this fic. Go back and read it if you didn't
