Tsunade(綱手,Tsunade) Tsunade's name is taken from the character of the same name from Jiraiya Goketsu Monogatari (児雷也豪傑物語, "The Tale of the Gallant Jiraiya"). The Tsunade in that story excelled in snail magic and was married to Jiraiya. The name "Tsunade" (綱手) means "mooring rope."
Tsunade's trademark ability is her superhuman strength, which is derived from her excellent chakra control. By storing chakra and releasing it at the point of contact, she can enhance her strength to the point where she can break through boulders with her bare hands or, as seen with her Painful Sky Leg (痛天脚,Tsūtenkyaku, English games "Legendary Heel Drop"), create a gigantic crater by simply kicking the ground. In addition, Tsunade can convert a small amount of this chakra to electricity for her Important Body Points Disturbance (乱身衝,Ranshinshō). Once opponents are struck by this, the electrical flow of signals from their brain to the rest of their body is disrupted, causing their leg to move when they attempt to move their arm, for example.
She is also an extremely talented Medical-nin, and can use medical jutsu to heal wounds that most others would consider impossible.
