Flying Thunder God Technique (Hiraishin No Jutsu)

Without a doubt, this was one of Tobirama’s signature and most devastating abilities. Its instantaneous teleportation allowed him to outmaneuver virtually any opponent, strike with incredible speed, and even redirect attacks. He could mark multiple locations, allowing for strategic movement across the battlefield. The speed granted by this jutsu made him incredibly difficult to target.

A technique that creates physical copies of the user, each capable of independent action. This is a fundamental jutsu with versatile applications.
Impure World Reincarnation (Edo Tensei)

While a forbidden jutsu, it’s power is undeniable. Tobirama could bring back the dead as immortal warriors under his control. These resurrected individuals retained their former abilities, making them formidable opponents. He demonstrated the ability to control multiple powerful individuals simultaneously, turning the tide of entire wars.
Water Dragon Bullet Technique (Suiryudan no Jutsu )

Tobirama was an exceptionally skilled water-style user, capable of creating massive and powerful water dragons even without a nearby water source. This justu possessed immense destructive force and could overwhelm opponents.
Water Formation Wall (Suiton: Suijinheki)
A highly effective defensive jutsu where Tobirama could create a powerful wall of water to protect himself and others from incoming attacks. Its strength could vary depending on the amount of chakra exerted.
Darkness Genjutsu (Kokuangyo No Jutsu)

This genjustu plunged the target into complete and utter darkness, robbing them of all five senses. In such a state, opponents become incredibly vulnerable to attack as they lose all spatial awareness.
Mutually Multiplying Explosive Tag (Kage Buyo)

After reading this post you will find that the 20 S-rank shinobi who have attacked the Tobirama Senju were all the god-tier level, or all kage-level shinobi.
Conclusion of how strong Tobirama was:

It’s crucial to remember that Tobirama was not only powerful but also a master strategist and inventor. In a real fight, he would likely leverage his extensive knowledge to create specific counters for his opponents, as demonstrated in his strategies against the Uchiha clan.
Another vital point to consider is that during his tenure as Hokage, the Leaf Village did not experience a single major attack from the outside. In contrast, Hashirama’s time saw Madara’s betrayal, Hiruzen’s era witnessed the Uchiha clan massacre, Minato faced the Nine-Tails’ attack, and Tsunade endured Pain’s assault. Tobirama remains the only Hokage under whose leadership the village thrived without any external threats, and even the Uchiha clan didn’t dare to unleash the Nine-Tails or betray the Leaf.
Furthermore, we must not forget the foundational systems he established, which later became the backbone of the Leaf’s strength, such as the ANBU, the Ninja Academy, and the Jonin Commander system.
Therefore, fans who believe it took twenty S-rank ninja, including one as powerful as an Akatsuki member, to defeat him should remember that the Akatsuki also had weaker members. Only the top four members of the Akatsuki would have stood a significant chance against Tobirama.
