The Uchiha clan is one of the strongest known clans in the world of Naruto the members of which possess the power of the Kekkei Genkai known as the Sharingan. Most of its members are considered to be fearsome shinobi with powerful Jutsu up their sleeves, some of which are accessible through the Sharingan, and others which stem from their affinity to Fire Release.
Over the years, lots of powerful techniques have been displayed by the members of the Uchiha clan, and the strongest ones can defeat even the mightiest of shinobi.
10 STRONGEST: Amaterasu
Amaterasu is a Jutsu that is accessible to certain users of the Mangekyo Sharingan, such as Sasuke Uchiha and his brother, Itachi Uchiha. This Jutsu lets them create black flames that can't be extinguished until the target is burnt down completely.
The flames are said to be as hot as the sun itself, making it incredibly difficult to deal with for any opponent. Even evading this Jutsu is a task that requires a lot of effort.
9 WEAKEST: Genjutsu: Sharingan
Genjutsu: Sharingan is a basic genjutsu that all users of Sharingan can perform. When compared to the likes of Tsukuyomi or Kotoamatsukami, this technique isn't all that special.
Nonetheless, the control one has over this Jutsu varies. A highly skilled user of this technique can certainly defeat even strong opponents with this basic technique, however, it remains to be one of the basic Uchiha Jutsu.
8 STRONGEST: Izanagi
Izanagi is a powerful genjutsu that people with the Sharingan can use in exchange for their eyesight in that eye. This Jutsu is forbidden as it harms the user and messes with the laws of reality itself.
Izanagi allows the user to make an illusion into reality, which is unlike any other genjutsu in the series. It is so powerful that as long as it is active, the user will gain absolute control over reality. Obito Uchiha could keep Izanagi activated for 10 minutes while someone like Danzo didn't have much control over it.
7 WEAKEST: Copying Other Jutsu
The Sharingan has a powerful ability that allows it to copy all the other techniques, be it Ninjutsu, Genjutsu, or Taijutsu. However, the user must be skilled enough to be able to use the techniques copied.
While this is a very useful power, it doesn't work on Kekkei Genkai and Hiden Jutsu, which is what the majority of the stronger powers in the series are. Furthermore, the importance of this power diminished significantly towards the end of the Naruto series.
6 STRONGEST: Izanami
Just like Izanagi, Izanami is a Jutsu that comes at the cost of the user's eyesight, however, it is extremely powerful. This Jutsu was made to counter Izanagi and its power is known to be immense.
Izanami allows the user to set up an illusionary but never-ending loop and trap their target in for eternity. The only way to break out is to acknowledge their faults and take the right path, which makes it an undefeatable technique. So far, only Itachi Uchiha has been seen using this Jutsu in the story in his fight against Kabuto.
5 WEAKEST: Demonic Illusion: Shackling Stakes Technique
Known to be a paralysis Genjutsu that is based on Genjutsu: Sharingan, the Shackling Stakes technique was used quite often by Itachi Uchiha, and on one such occasion, he managed to defeat Orochimaru with this technique within a matter of seconds.
It traps the opponent in a world of illusion where they're tortured with the feeling of having spikes driven through their entire body. This technique is undoubtedly strong, but it certainly pales in comparison with the other Uchiha Jutsu.
4 STRONGEST: Susanoo
The Susanoo is one of the most powerful Jutsu in the entire Naruto series, and it is accessible only to those who have awakened the power of Mangekyo Sharingan in both eyes. Susanoo is a massive humanoid of chakra that the user can summon at any point to fight on their behalf.
At full power, it can reduce mountains to dust, and not even the Five Kage standing together are enough to face its might.
3 WEAKEST: Fireball Jutsu
Fireball Jutsu is one of the most basic techniques that an Uchiha can perform. While this Jutsu isn't limited to the members of the Uchiha clan members in any way, it is usually best performed by them as they have a very strong affinity for Fire Release techniques.
This Jutsu is usually mastered by the Uchihas at a very young age and with enough skill and experience, this technique can prove to be deadly. Despite that, it doesn't compare to the other Uchiha Jutsu.
2 STRONGEST: Nine-Tails Control
The strongest power of the Sharingan, or more specifically its evolved form, the Mangekyo Sharingan, is its ability to control the Nine-Tails. Any skilled user of this eye can bind the Nine-Tails down to a summoning contract and use it at will.
Madara Uchiha and Obito Uchiha both utilized this power to destroy Konoha, however, both of them failed. In the anime, Fugaku stated that his Mangekyo Sharingan was strong enough to control the Nine-Tails as well.
1 WEAKEST: Phoenix Flower Jutsu
Another Fire Release technique that is mostly performed by the members of the Uchiha clan, the Phoenix Flower Jutsu is a technique that allows the user to spew many fireballs at once and be able to control each one of them individually over a decent range.
It's strong enough to incinerate a target and since it can be controlled, it is difficult to evade. However, this Jutsu is just a C-rank technique and thus lacks firepower.
