1. The Frog Sage Contract: This ability can only be formed by a few ninjas with Mount Myoboku. Jiraiya was the first to form this contract after being prophesied by the Great Toad Sage. He learned senjutsu and formed a contract with the toads. Jiraiya assisted the Fourth Hokage in defeating the Nine-Tails during the attack on Konoha.

2. The Monkey King: The strongest summoning creature, as powerful as the Third Hokage.

They defeated many enemies together. The Monkey King can use ninjutsu and transform into an indestructible staff. The Third Hokage used the staff to drive the Nine-Tails out of the village during the attack.

3. Giant Stone Statue: When the Sharingan or Byakugan evolves, new abilities are gained. For example, Itachi gained Tsukuyomi and Amaterasu with his evolved Sharingan. The evolved Byakugan, called Tenseigan, grants the power to control the Giant Stone Statue.

Kaguya Otsutsuki used the statue to suppress the Nine-Tails, which Naruto eventually defeated.

4. Gedo Mazo: This vessel holds the Ten-Tails and can contain the chakra of all nine Tailed Beasts. Madara Uchiha controlled Gedo Mazo and the Tailed Beasts during the Fourth Great Ninja War. Even the strongest Nine-Tails couldn't escape its control.

5. Ten-Tails: Obito used the chakra of the Eight-Tails and Nine-Tails to partially revive the Ten-Tails. It overwhelmed the Nine-Tails and Eight-Tails, showing a significant power difference.
