Fuen

How Fuen joined the Tourney
Fuen, along with Fudō and the rest of her team, searched through the graves of the Twelve Guardian Ninja, and took with them the encapsulated corpses of Kitane, Nauma, Seito and Tōu as plunder. All four bodies were crucial in Furido's plan to destroy Konoha, for in reanimating them, he'd be able to take control of the four and force them into using the Limelight technique — a technique that has enough potential to destroy villages within seconds. Team 7 caught onto their tracks, which prompted them to chase Furido's team throughout the land. In their trek, Fudō, Fuen and Fūka stopped to retaliate while Furido continued on with the bodies. After Fudō's summoning of a rocky labyrinth, Fuen headed out into the battle field and took on Sai. Here, she displayed a sense of boredom while in battle, which prompted her to toy around with Sai. Eventually, the battle came to a close when she struck down one of his ink clones.

At the start of Furido's invasion of Konoha, Fuen ensured that no villagers could escape by performing the Barrier Gate Five Seals Technique: Castle Closing Eight Gates. Soon enough, Furido's destructive plan was discovered by some of Konoha's ninja, thus, Fuen went off to stop anyone from interfering, and whilst doing so came across Sakura Haruno. Fuen managed to trap her within her moth swarm genjutsu, and after incapacitating her, went in for the kill with her spears of stone. Surprisingly, Fuen had in actuality fallen for Sakura's own trick. Fuen was so stunned by what had happened that she didn't notice the real Sakura emerging with an enraged and disgusted Sakura calling Fuen "a sick freak" before Sakura used her strength to punch Fuen, the impact sending Fuen through some trees and even causing one to collapse. Sakura then revealed that she'd taken an antidote after having run some simulations as well. After said revelation, Sakura then punched Fuen in the chest, the impact killing Fuen instantly with Fuen's death also cancelling the barrier Fuen herself had placed around the village.

Having resurrected by Quan Chi, Fuen is ordered to gather warriors for the Netherrealm invasion of Nintendo Land. However, she was obstructed by a sorcerer named Baron Mordo.

After the announcer calls her name
Fuen summons stalagmites and cuts one of them, scattering the rocks as the camera zooms and says "I designed this terrain and summoned it into being."

Earth Style: Spears of Stone (Neutral)
Fuen forms a staff made of rock in her hand. Once that happens, she can change her normal and Smash attack pattern. If B is pressed again, she can throw the staff at her opponent.

Earth Style: Hidden in Stones Jutsu (Side)
Fuen sinks into the air and comes out after a few kick, kicking her opponent.

Earth Style: Stone Smasher (Up)
Fuen uses a staff made of rock to pierce forward then rise into the air swinging the weapon.

Altering Terrain Technique (Down)
Fuen draws on her map what appears to be an ordinary treasure chest. If the opponent goes anywhere near it, the chest shows teeth and tries to bite the opponent.

Earth Style: Pikes of Stone (Hyper Smash)
Fuen makes several staves, snaps her fingers and launches them at the target.

Poison Moth Genjutsu (Final Smash)
Fuen first uses poison that is thin and tiny enough to be taken in the air. If the opponent touches the toxic mist, they will begin to see a luxorious beach, and their known allies trying to kill them and sharks and killer whales coming out to attack. When her target is imprisoned in her genjutsu, Fuen charges and kills her target.
