Hashirama was called the God of Shinobi. Hiruzen was called it way back in early Part 1, along with a few other retconned statements about his strength. Whilst that moniker was swept under the carpet in regards to him, he did retain his title as “The Professor”, thanks his vast knowledgeable about ninjutsu.

Takemikazuchi (建御雷/武甕槌) is a deity in Japanese mythology, considered a god of thunder and a sword god. He also competed in what is considered the first sumo wrestling match recorded in history.
Many of the most powerful techniques shown in Naruto and Boruto were already described as "god-tier", but the revelation that there is an actual god, and that every ninja technique is just a pale imitation of his powers, will certainly upset the shinobi world for a long time.
Kakashi is a master of over a 1000 jutsu but these are some of his rarest techniques. Kakashi Hatake is one of the most powerful characters in the Naruto world.
