Kakuzu vs Harashima
ERmmm...Yeah >_>
Kakuzu vs Tobirama

Aside from his battle prowess, Tobirama was also a very gifted sensor ninja since childhood. By simply touching the ground with his index finger, he could detect the presence and number of enemy shinobi. He was even able to detect Madara Uchiha's chakra on a battlefield countries away. His sensory skills were so refined and accurate that he could distinguish between different chakra signatures by clan, as upon sensing Karin, he determined she was an Uzumaki. He was also able to notice how Orochimaru's new body was made almost entirely of Hashirama's cells. He could use his abilities, along with his tracking skills, in order to follow a target undetected.
Tobirama was primarily known for his legendary mastery of Water Release. He could use the Water Release: Water Encampment Wall in an area that lacked a pre-existing body of water by spewing water out of his mouth, then use the water produced to follow up with another technique, such as the Water Release: Water Dragon Bullet Technique, using only a single hand seal to perform the latter. He could further manipulate water by isolating areas within it and evaporating it at will. These, among other reasons, are why he is revered as the greatest known Water Release manipulator in the series.
The hearts captured from other ninja granted Kakuzu numerous elemental affinities, along with a vast supply of chakra. By collecting these hearts Kakuzu's own affinity is reinforced and his skill in other elements is increased to the point that he was able to use various different elemental attacks that were noted to be impossible, without having an affinity to that particular element. This is done by connecting his chakra circulatory system to his four extra hearts, granting him the ability to change his chakra nature and affinity to that of the previous owner. The individual hearts could be released from his body and wrapped in a vast blanket of threads, forcing a heart into a limb before being detached or forming a monstrous body with a mask as its face. These masks could move and attack independently, unleashing powerful blasts of elemental chakra from their mouths. The hearts that Kakuzu had stolen prior to his death, belonged to his previous partners in Akatsuki.

Water mask: This heart had an water affinity
Fire mask: This heart had a fire-affinity, and took on the shape of a demonic tiger. It could use Fire Release: Intelligent Hard Work. This mask could also unite with the Wind mask to launch a fire-wind dual strike that was near unstoppable.
Lightning mask: This heart had a lightning-affinity, and took on the shape of some sort of deformed biped. It could use Lightning Release: False Darkness.
Wind mask: This heart had a wind-affinity, and took on a strange four-legged body with thin wings. It could use Wind Release: Pressure Damage. It could unite with the Fire mask to launch a fire-wind dual strike that was near unstoppable.
None of these are a good combination for Tobirama at all. Yes, Tobirama has space time, but he would have to use it 5 times. Kakuzu's Main affinity, wich cant be taken away through anything we have seen from Tobirama. By combining both his Fire and Wind mask, he can overcome fire's weakness, water, and evaporate it almost instantaneously . It took out about 3 water walls.
Most Water techniques are used and released from the mouth, the Lightning mask can shoot lightning beams at an incoming water technique which would short-circuit in the water and paralyze Tobirama.
He is immune to water techniques completely, by covering himself in dense Earth, he can tank any water technique that manages to hit him.
As far as his Genjutsu goes, we have only seen False Darkness, it wouldn't take a Genius to figure out and thus, he could just use kai.
Kakuzu's arsenal and combos will completely defend and overpower Tobirama. Kakuzu also has water affinity, he can manipulate any water source, Tobirama creates, however, without a doubt Tobirama's water >>> Kakuzu's Water
Kakuzu vs Hiruzen
In terms of taijutsu, Hiruzen displayed a very high level of skill. He was able to counter Hashirama and Tobirama in close combat. He was also quick-thinking as during their confrontation he was able to place explosive tags on each of them without them, nor Orochimaru even knowing. After summoning Enma, he was able to break through wooden branches with ease.

Even when robbed of his sight, he could still defend himself from Hashirama's and Tobirama's assaults, blocking all their attacks to prepare for his Dead Demon Consuming Seal. After sealing both former Hokage, he faced Orochimaru in single combat. Despite his sealing parts of his soul away in the Shinigami, as well as fighting for a prolonged amount of time before he engaged Orochimaru one-on-one, he effortlessly disarmed him of his sword.
Sarutobi was highly skilled in elemental ninjutsu, using Fire Release and Earth Release. Fire Release: Fire Dragon Flame Bullet allowed him to exhale a powerful stream of fire from his mouth. Earth Release: Earth Flow River created a river of mud beneath the opponent to throw them off balance, and he could use the mud with Earth Release: Earth Dragon Bullet, which creates a dragon's head that launches mud balls at an opponent. He had also been shown to be adept in combining elemental techniques, as seen when he ignited the mud ball projectiles with Fire Release: Fire Dragon Bullet, creating a volley of hot mud that can melt nearly anything. Earth Release: Earth-Style Wall allowed Hiruzen to spit a stream of mud that solidifies into a protective shield.
Hiruzen also had a personal summon: Monkey King: Enma, who was capable of turning into a diamond-hard staff, which could alter its length and width at will, or become a cage to protect the summoner. The staff was Hiruzen's weapon of choice as he showed great proficiency in wielding it; he successfully pushed back Kurama with it during its attack on Konoha. Enma could also manifest parts of his body and attack an enemy with his claws and fangs, which added an element of surprise.
First, lets talk about Taijutsu. Kakuzu can be completely unaffected by taijutsu. The staff is as hard as diamond, so is Earth Release: Earth Spear. Hiruzen doesn't posses anything that can actually pierce through domou, considering the fact that it is only weak to lightning release. However, Hiruzen was never shown to use any shape or form of raiton, therefore, Hiruzen cannot pierce it.
Hiruzen's earth jutsu are simply Mud manipulation, nothing stone, thus he wont be able to penetrate through domou as its well, not dense enough.
Kakuzu possesses water release, which would easily smother and extinguish fire release. Im sure Kakuzu's Large scale Fire release would overpower hiruzen's small techniques and continue on. Kakuzu could stack on a pressure damage and increase its size, heat and potency. Hiruzen has, within his arsenal, nothing shown to counter fire/wind combos.
Kakuzu's lightning release can break through and neutralize/over power earth release.
Also, Hiruzen has low stamina due to his old age, less speed, less accuracy and less strength, His chakra levels will deplete rather fast, and Hiruzen has nothing to counter not one single jutsu within Kakuzu's arsenal.
Kakuzu vs Minato

In his youth, Jiraiya taught Minato how to use the Summoning Technique to summon toads. He was able to summon Gamabunta, showing considerably large reserves of chakra in doing so, and was one of the few people that Gamabunta would willingly cooperate without hesitation. He could use the Summoning: Food Cart Destroyer Technique for a devastating surprise attack that could even pin powerful large targets like the Nine-Tails down.
Minato was famous for his use of the Flying Thunder God Technique, a space–time technique applied through the use of special seals, which essentially allowed him to teleport to any location with untraceable movements. By throwing kunai that had the seal attached to them behind enemy lines, Minato could wipe out an entire platoon in the blink of an eye. Minato could teleport to his special kunai even as it travelled through the air, through this method, he was able to outmanoeuvre Tobi's Kamui. He was also capable of applying the seal to solid surfaces with his bare hand, allowing him to tag opponents and give himself an easy way to track and reach them. He also incorporated this seal formula into Kushina's seal so he could always come to her aid, at any time. Minato is also capable of transporting multiple people to different markings simultaneously.
For defensive use, Minato was capable of implementing space–time barriers to counter large attacks such as a Tailed Beast Ball, sending the blast to a distant area away from the village. He was later even able to warp away a Tailed Beast Ball of larger proportions created by the Ten-Tails, and was able to teleport things even as large as the Nine-Tails itself, albeit at the cost of a large portion of his chakra due to the beast's immense size.
