Of Course Kakashi is a strong Charackter BUT TSUNADE IS A HIGHER LEVEL SHINOBI !!!
Tsunade is the powerfulst Kunoichi she survived the heavenly Transfer Technique wich is said that only the third Raikage can survive it after that she attacked Madara very fast and healed Onooki and Gaara
She Activated a new Jutsu The Byakugou Jutsu wich allows her to regenerate any kinds of wound without to perform any hand seals like her grandfather she breaked Madaras Susanoo witch full force wich until now is the first Time that a naruto Charackter coud break a susanoo she blitzed madara and destroyed his hole body beeing impaled with his susanoo blade she crushed his blade with her hand and started a counter attack and almost hit madara tanked a YASAKA MAGATMA Then she fought from day until night still her byakugou jutsu is active against madaras five clones she was impaled with two susanoo blades and still took down madaras susanoo she gaved oonoki great suplies of chakra so that he can use a huge jinton after that still her byakugou no jutsu was active before any kage coud react she beat madaras katon with her bare hand away a great speed factor and now CUT IN HALF SHE STILL MANAGED TO SUMMON KATSUYU AND THINK TO HEAL THE OTHER KAGES
SO TO YOU ALL TSUNADE THE GREAT HOKAGE OF THE LEAF SANNIN HASHIRAMAS DESCENTAND COUD GIVE KAKASHI A VERY GOOD GIGHT AND EVEN BEAT HIM BECAUSE MADARA IS MUCH MORE STRONGER THAN KAKASHI
