Kizaru, a character from the anime One Piece, possesses the Pika Pika no Mi Devil Fruit, which grants him the ability to move at the speed of light. While this ability allows him to move incredibly fast, it does not make him infinitely fast. The concept of infinite speed is not achievable in the real world or in fictional universes, as it would violate the laws of physics. Therefore, while Kizaru is extremely fast, he is not infinitely fast. **

Borsalino Kizaru is a powerful character in the One Piece series, known for his incredible speed and light-based abilities. While he is a formidable opponent, he is not invincible. Like all characters in the series, Kizaru has his weaknesses and limitations that can be exploited by skilled opponents. Additionally, in the world of One Piece, there are characters with even greater strength and abilities that could potentially defeat Kizaru. **

While Usopp has shown significant growth and improvement in his abilities throughout the series, it is unlikely that he could become as strong as Kizaru. Kizaru is one of the three admirals in the Marines, known for his incredible speed and powerful light-based abilities. Usopp, on the other hand, is a skilled sniper but lacks the physical strength and combat prowess that Kizaru possesses. However, with determination and training, Usopp could continue to enhance his skills and make significant contributions to his crew. **

If Gol D. Roger gets serious against Kizaru, it would likely be an intense and epic battle. Both characters are incredibly powerful and skilled fighters, so the clash between them would be a sight to behold.

Roger's legendary status as the Pirate King, it's possible that he could come out on top in a serious battle against Kizaru. **

Admiral Kizaru is approximately 6'6" (198 cm) tall, Admiral Akainu is around 9'10" (300 cm) tall, and Admiral Aokiji is about 9'2" (280 cm) tall. These measurements are based on their appearances in the popular anime and manga series, One Piece. Keep in mind that these heights are not officially confirmed by the creator of the series, Eiichiro Oda, and may vary slightly in different sources. **

Akainu is considered to be stronger than Kizaru primarily due to his Devil Fruit ability, the Magu Magu no Mi, which allows him to create and control magma. Magma is known for its destructive power and ability to cause widespread devastation, giving Akainu a significant advantage in combat. Additionally, Akainu's ruthless and relentless fighting style, as well as his strong sense of justice, make him a formidable opponent. Overall, these factors contribute to the belief that Akainu is stronger than Kizaru in the One Piece universe. **
