20She Can Change Her Age At Will
In order to avoid paying her gambling debts, Tsunade designed a ninjutsu that allows her to alter her appearance at will without having to exert any effort. She can shift how old or young she appears at will, and this is why she looks like she’s in her
mid-twenties, despite being in her fifties and sixties as the series progresses.
The only downside to this ability is that if she runs out of chakra, she will revert back to her natural appearance immediately. While she really only uses this technique to appear in her mid-twenties over the course of Naruto, hopefully, fans of the series will get to see all the shenanigans that come along with this power in the sequel series, Boruto: Naruto Next Generations.
