After helping him regain the essentials of his combat reflexes, Shiva then pits Bruce against several vengeful expert martial artists, having killed their master while wearing a distinctive "tengu" mask that carries a motif of a bat that she subsequently gives to Batman. Shiva's caveat is that these attacks will continue indefinitely until Bruce Wayne breaks his vow to never kill. Finally, in the midst of an attack by the final martial artist, Bruce feigns using the "Leopard Blow" fatal maneuver Shiva had taught him, leaving his would-be assailant apparently dead. Shiva finally declares him worthy of fighting her at some point in the future, with Bruce only revealing his adversary's survival to Nightwing and Robin after her departure. Shiva would later learn the truth. Now back in fighting shape, Bruce returns to the Batcave and resumes his role as Batman. Along with Robin and Nightwing, he tracks Valley down to Selkirk's penthouse. Coincidentally, Catwoman is chasing the same man because he owns a neural enabler which might allow her paraplegic friend to walk again. Selkirk already wants to kill Jean-Paul for destroying a valuable weapons cache in Gotham Harbor. When they eventually all meet, mass fighting and gunfire ensue. The battle ends with Selkirk's helicopter crashing into the Gotham Narrows Bridge while Bruce and Jean-Paul fight on the attached Batrope; Jean-Paul falls aflame into the Gotham River. Bruce and Catwoman save Selkirk and his aides just before the helicopter explodes from the leaking fuel, his decision to protect criminals affirming to Catwoman that the true Batman has returned. When Bruce tries to find Jean-Paul using the Batmobile, it explodes due to a planted booby-trap. Nightwing fears Bruce dead and takes his vengeance out on Jean-Paul on a party boat. The police arrive in time to prevent Nightwing from committing murder, but Jean-Paul escapes. However, to his shock, Jean-Paul finds Bruce waiting at Wayne Manor; Bruce had managed to escape the Batmobile before Jean-Paul's trap destroyed it, reasoning that he would have done the same thing with a less dangerous trap. The final battle of the "Knightfall" saga takes place between Jean-Paul Valley and Bruce Wayne in the caverns surrounding the Batcave below Wayne Manor: rather than beating Jean-Paul at hand-to-hand combat, Bruce outwits him by escaping into a passage too narrow for Jean-Paul to go through in his armor, thus forcing Jean-Paul to remove most of it.
