Gaara's Bijuu is the One-Tail, also known as Shukaku. Shukaku is a tailed beast that takes the form of a tanuki and possesses the ability to control sand. It was sealed within Gaara when he was just a child, leading to his isolation and the development of his ruthless and unstable personality. However, as the series progresses, Gaara learns to control and work with Shukaku, ultimately using its power for the greater good. **

When a Bijuu dies, it releases a massive amount of chakra, which can cause widespread destruction and devastation. The chakra released from the Bijuu's death can potentially harm or even kill those in the surrounding area. Additionally, the death of a Bijuu can upset the balance of power in the ninja world, leading to potential conflicts and power struggles among different factions vying for control of the Bijuu's chakra. Overall, the death of a Bijuu has significant and far-reaching consequences for the ninja world. **

While Naruto's Bijuu Mode grants him immense power and abilities, it does come with risks. One of the main risks is the potential loss of control over the Nine-Tails' chakra, which can lead to destructive behavior and harm to those around him. Additionally, relying too heavily on the Bijuu Mode can exhaust Naruto's own chakra reserves, leaving him vulnerable in battle. Overall, while Bijuu Mode is a powerful tool, it is not without its risks and drawbacks. **

The Bijuu, also known as Tailed Beasts, possess immense power and abilities. Each Bijuu has a unique set of abilities, but they generally have immense chakra reserves, immense physical strength, and the ability to use powerful chakra-based attacks such as Tailed Beast Bombs. They can also communicate telepathically with their hosts and have the ability to sense and manipulate the emotions and thoughts of others. Additionally, they have regenerative abilities and can survive even fatal injuries. Overall, the Bijuu are incredibly powerful entities with a wide range of abilities. **

Sora's Bijuu spirit is not as strong as Naruto's. Naruto possesses the Nine-Tails, which is one of the most powerful tailed beasts, while Sora's Bijuu spirit is the Six-Tails. The Nine-Tails has shown immense power and destructive capabilities throughout the series, making it one of the strongest tailed beasts. While Sora's Six-Tails is still formidable, it is not on the same level of power as Naruto's Nine-Tails. **

After the 4th Ninja War, the Bijuu are all freed from their jinchuriki hosts and are allowed to roam freely in the world. They are no longer seen as weapons of war but as powerful entities that can coexist peacefully with humans. The Bijuu are shown to have developed individual personalities and are seen interacting with humans in a more positive light. Overall, the Bijuu are no longer feared and are integrated into society in a more harmonious way. **

The three-tailed Jinchuuriki in Naruto is Yagura Karatachi, who was the Fourth Mizukage of the Hidden Mist Village. The Bijuu sealed within him is the Three-Tails, also known as Isobu, a turtle-like creature with three tails. Yagura was manipulated by Obito Uchiha and the Akatsuki to become the Jinchuuriki of the Three-Tails. **

No, Gaara no longer has the Bijuu spirit within him in Naruto. The Bijuu spirit, Shukaku, was extracted from Gaara by the Akatsuki organization during the events of Naruto Shippuden. After its extraction, Gaara's life was in danger, but he was saved by Naruto and his friends. Gaara no longer possesses the Bijuu spirit and is no longer a Jinchuriki. **
