Kage
The top ninja rank in Naruto, which means "shadow" in Japanese. There are five Kages, like the Fire Shadow, Wind Shadow, Water Shadow, Lightning Shadow, and Earth Shadow. They are all tough as hell and would kick your ass if you messed with them.
"You think you’re a ninja? I’m the Hokage, and I could take you down in one hit."
"The Raikage is like a lightning bolt with a temper."
"The Tsuchikage is so strong, he could crush mountains."
