1. Sage Mode: Sage mode grants the user unlimited natural energy, separate from Hagoromo's chakra. It has been used to counter the Sharingan and enhance power, making it a valuable ability for Naruto and Jiraiya. Sakura, with her summoning contract and the Byakugo no Jutsu, can potentially master the Shikkotsu Forest Sage Jutsu to maximize healing speed and strength.
2. Byakugan: To maintain fairness, Sakura should have her unique ability.
3. Tailed Beast Power: Sakura can learn the Hundred Healings Jutsu, a secret art of the Fifth Hokage, Tsunade. With enough chakra, Sakura can heal injuries and fight without worry. Becoming a Jinchuriki would further enhance her ability to use this jutsu effectively.
4. Wood Release: Wood Release, the strongest nature transformation, can counter the Sharingan and overpower tailed beasts. If Sakura gains control over this ability, her power will surpass Naruto's Nine-Tails Mode and Sasuke's Susanoo.
5. Eight Gates Released Formation: The Eight Gates Released Formation is an incredibly powerful but deadly technique. However, by combining it with the Hundred Healings Jutsu, Sakura could potentially overcome its drawbacks. With her monstrous strength, even formidable opponents like Madara Uchiha would be defenseless against her.
