Fudō

Fudo is shinobi that appears in the first filler arc of Shippūden, he is part of the group of grave robbers who have dug up four of the dead Twelve Guardian Ninja. He is the brute force of the group and is usually seen pairing up with Fuen.

Personality
Fudo is portrayed as an arrogant brawler, further enhanced by his wild hair and bear-like stature. He has great confidence in his abilities and despises being looked down upon. During his first battle against Team Yamato, he ridiculed Fuen for not giving him the credit he deserved for the trap. Fudo, being so reliant on his strength, tends to underestimate his opponents and thereby allowing smarter opponents to easily deceive him.

Fire Temple Filler arc
Fudo made his first appearance with Fuen looking for one of the four lightning-chakra users of the Twelve Guardian Ninja.

Later when he and his allies met up with Team Yamato, he used his impressive mastery of earth-chakra to change the landscape into a rocky canyon. After successfully trap their targets, Kazuma faced off against Yamato. He was initially impressed that Yamato could use the infamous Wood Release of the First Hokage, but quickly found his opponent as waste of time. He quickly took the offensive with his head-on brute strength. Yamato, ineffectively, tries to defeat his opponent using wood style jutsu. These attack were simply scoffed at thanks to Fudu's stone-like armor. Fudo eventually "finished" the fight by seemingly crushing Yamato with an earth jutsu, not aware that Yamato had escaped unharmed.

Later during the attack on Konoha, played a huge part in the invasion by once again altering the terrain to suit his team's plan. With a new twist, Fudo's jutsu summoned hundreds of undead ninja to preoccupy the Leaf ninja. Fudo then once again found himself up against Yamato. At first things played out the same as it did last time thanks to Fudo's armor, but Yamata was able to deduce that while very durable, Fudo's armor was very susceptible to water.

Using this edge, Yamato tricked Fudo into widening the area from his reckless attacks. Yamato went on the offense with a water-based jutsu that drenched the area, causing Fudo to sink underground. Yamato then finishes off Fudo by trapping him in a wood-based justu. Upon his death, Fudo's last jutsu is canceled, causing all the zombies to turn to dust and the village to return to normal.

Abilities
Fudo battle style relies mainly on his earth element jutsu and physical strength. Despite his brutish nature, he has proven to be very crafty and skilled in earth-based jutsu, being able to use such wide-scale technique with seemingly no effort and to help catch his opponents off guard. During the initial attack on Konoha, his earth-based prowess was shown from being able easily take down dozens of Leaf ninja while almost casually walking towards his destination. The pinnacle of his earth-chakra prowess has been seen from his ability to summon earth and alter it around the entire terrain to suit his jutus needs. Another ability of his is to utilize his earth chakra to absorb the properties of stone around him to form a skin-deep armor capable of defending him from nearly all forms of physical attacks and at the same time make his strikes more destructive.

In addition, he has demonstrated tremendous taijutsu prowess as evident from how many Leaf ninja he took down on his own. He has also shown tremendous strength as seen from how effortlessly he broke free from Yamato's wood bindings. Also, he can summon chakra into the palm of his hand to become visible and enhance his strikes. His precision of this was shown great enough to easily imprint a Leaf Village symbol in rock..

Trivia
