Over the course of Batman’s illustrious career, he has won many a battle but lost one that almost cost him his life. The battle I refer to is the one where he fought Bane. Bane was born in the 
Caribbean Republic of Santa Prisca, in a prison called Peña Dura. He has come to Gotham City, with one thing on his mind, the destruction of Batman. This battle takes place well over 6 months, as Bruce Wayne (Batman) suffers burnout and is systematically assaulted and crippled. Bane has freed all of the maximum-security inmates of Arkham Asylum, a notorious psychiatric facility in Gotham City. Aware that he would lose in a direct assault against Batman, Bane's plan consists of weakening Batman by forcing him to deal with the deadly villains simultaneously. The scenario creates a rift in the relationship between Robin and Batman, as Batman irrationally seeks to face the outbreak alone, this situation makes Robin ask Batman if he is even needed as his sidekick anymore.
Batman becomes weaker and weaker as each criminal is put away. The rescue of Mayor Krol from the teaming of the Joker and Scarecrow pushes Batman to his mental and physical limits: a dose of Scarecrow's fear gas makes him relive the murder of Jason Todd, which he considers to be his greatest failure. 
After this encounter, Bane makes his move and attacks Batman at Wayne Manor, as Bane has deduced the secret identity of Batman. By this time, Batman is so exhausted from the exertion of catching the escaped criminals that he cannot even defend himself; Bane beats him mercilessly before breaking Wayne's back over his knee inside the Batcave below the manor, symbolically "breaking" Batman and leaving Wayne a paraplegic.
Bane takes the grievously-wounded Wayne (still costumed in the Batman outfit) downtown to Gotham Square and throws him from a rooftop to demonstrate his superiority to the populace. With Batman incapacitated, Bane establishes himself as the new ruler of Gotham's criminal underworld, Bruce Wayne passes the mantle of Batman to Jean-Paul Valley, also known as Azrael. 
As the "new" Batman, however, Jean-Paul grows increasingly violent, ruthless and has little to no regard for innocent bystanders. During this time, he drives Robin away because he believes Gotham to be so tough that only violence could answer its criminals. Returning to Gotham, Bruce meets with Tim. Even though Jean-Paul disobeyed Bruce's order to refrain from attacking Bane, Bruce is sufficiently impressed with Jean-Paul's results. Bruce decides to retire and allow Jean-Paul to continue as Batman, but when Robin tells Bruce of the circumstances around Abattoir's death, Bruce sneaks into the Batcave and demands that Jean-Paul step down. Jean-Paul refuses and tells Bruce to leave the cave and never come back.
To rehabilitate his skills, Bruce asks the famed assassin Lady Shiva to retrain him. Instead, Shiva pits Bruce against several vengeful expert martial artists. Shiva's caveat is that these attacks will
continue indefinitely until Bruce Wayne breaks his vow to never kill. Finally, in the midst of another attack, 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. 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; 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. When Bruce tries to find Jean-Paul using the Batmobile, it explodes. 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.
The final battle 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. Bruce then opens a hatch to the outside, which covered the very hole he fell into as a child, allowing sunlight to enter the night lenses in Jean-Paul's helmet. After being momentarily blinded, Jean-Paul removes his cowl, sees Bruce standing over him in the original Batman costume and concedes defeat, saying "You are Batman...and I am nothing."
After defeating Jean-Paul, Bruce then set his eyes on Bane. Tracking him down, and exacting his own revenge on him, taking Bane out in a mere 40 seconds……
After everything that has happened in Bruce's life, Alfred takes it upon himself to bring in a new person, her name; Tatsu Yamashiro aka Katana. Alfred is worried about Bruce's well being, not his alter ego Batman, and asks Tatsu to become his Body Guard and Chauffeur. At first Bruce is against it, but after time, Tatsu proves herself to him, again and again. Bruce allows her to do this, and after a while reveals to her, who he really is. The two now go forth fighting crime, and she is never too far from Bruce's side.
