Both Kakashi and Obito possess unique versions of the Susanoo, a powerful protective and offensive technique in the Naruto series. Kakashi's Susanoo is a lighter shade of blue and is more streamlined in design, reflecting his calm and strategic nature. On the other hand, Obito's Susanoo is darker in color and has a more menacing appearance, symbolizing his darker past and more aggressive tendencies. Ultimately, the choice between Kakashi's or Obito's Susanoo comes down to personal preference based on which character's abilities and personality resonate more with the individual. **

Madara could use Susanoo because he possessed the Mangekyo Sharingan, a powerful form of the Sharingan that grants the user access to advanced abilities, including the ability to manifest Susanoo. Additionally, Madara had also awakened the Rinnegan, which further enhanced his abilities and allowed him to use Susanoo at an even higher level of power. With these powerful ocular abilities, Madara was able to manifest and control Susanoo to its full potential. **

Pain Nagato's Susanoo is a powerful technique in the Naruto series that is a manifestation of his inner spiritual energy. It takes the form of a giant, humanoid warrior with incredible strength and defensive capabilities. Pain Nagato's Susanoo is unique in that it is made up of mechanical parts, reflecting his cyborg-like appearance due to the modifications made to his body. This Susanoo is a formidable force in battle, allowing Pain Nagato to unleash devastating attacks and protect himself from harm. **

The strongest Susanoo is generally considered to be the Complete Body Susanoo, which is the final and most powerful form of the Susanoo. It is achieved when the user fully masters the abilities of the Susanoo and can manifest it in its complete form, with a full body and multiple arms. This form grants the user immense power and defense, making it the strongest version of the Susanoo. **

Obito never used Susanoo because he did not possess the Mangekyo Sharingan, which is a requirement for activating the Susanoo. Obito only had the regular Sharingan and later obtained the Rinnegan, but he never awakened the Mangekyo Sharingan. Additionally, Obito primarily relied on his Kamui ability and the power of the Ten-Tails as the Ten-Tails Jinchuriki, so he may not have felt the need to use Susanoo. Overall, Obito's lack of the Mangekyo Sharingan and his focus on other abilities likely contributed to his decision not to use Susanoo. **

One sees Shisui's Susanoo in the anime series "Naruto Shippuden." Shisui's Susanoo is a rare and powerful form of the Susanoo, a giant, humanoid avatar of chakra that is only accessible to those with advanced mastery of the Sharingan. Shisui's Susanoo is shown during a flashback in the series, where it is depicted as a sleek and elegant form with a unique design. **

I find the Susanoo from the anime "Naruto Shippuden" to be the coolest. It is a powerful and imposing warrior-like entity that surrounds its user, providing them with immense strength and protection. The design of the Susanoo in the anime is visually stunning, with intricate armor and unique abilities that make it a formidable force in battle. Overall, the Susanoo from "Naruto Shippuden" stands out to me as the coolest version of this mythical being. **

The Susanoo of Shisui Uchiha is a powerful and unique form of the Susanoo, a giant, humanoid avatar of chakra that is typically only accessible to those who have awakened the Mangekyo Sharingan. Shisui's Susanoo is known as "Kotoamatsukami," which grants him the ability to manipulate the thoughts and actions of others without them realizing it. This makes his Susanoo particularly dangerous and effective in battle, as it allows him to control his opponents without direct confrontation. **
