The Burly Brawl was an infamous fight between Neo and Smith, now a virus in the Matrix, during the near-end of the Machine War. Neo must use the powers of The One to fight off against Smith and his army of cloned copies of himself. At the end of the epic battle, Neo, realizing that he cannot fight against all of the clones, flew away from the area.
- "We can never see past the choices we don't understand."
"Are you saying I have to choose whether Trinity lives or dies?"
"No, you've already made the choice. Now you have to understand it."
- ―The Oracle and Neo [src]
During their conversation, The Oracle told Neo about his journey to The Source and to reach there, Neo must find the Exile known as The Keymaker as he is the only one that can lead him to The Source. Before their conversation ended, The Oracle informed Neo that The Keymaker is held captive by The Merovingian and Neo must find The Merovingian and rescue The Keymaker.
The Oracle wished Neo good luck before leaving the playground with Seraph through the door that they came in from. As soon as they left, Smith, from the far end of the playground, started walking towards Neo.
- "We're here because of you Mr. Anderson. We're here to take from you what you tried to take from us; purpose."
- ―Smith to Neo [src]
Before Neo left the playground, he senses something and turned to see Smith walking towards him, with the crows flying away. The program explained he was no longer an Agent of the Matrix and he wasn't sure how any of this came to be. Thanking Neo for "unplugging" him, Smith revealed his opinion that one exists with a purpose. With purpose as his lead for his new destiny, Smith decides that he must use his freedom to gain control of the system to satisfy his "purpose" and his desire.
At this same time, Neo heard another voice behind him. One by one, more Smiths revealed themselves from behind gates, doors, and other objects; each one adding to their monologue on the concept of purpose and why they will do what they aim to do..
Finally, the first Smith said to Neo his own personal goal: to rid Neo of life and purpose. Attacking without warning, Smith stuck his hand into Neo's body, instantly immobilizing him and spreading a black, liquid-like substance over the surface of his body. Back within the Nebuchadnezzar, Trinity, Morpheus, and Link watch the evnt take place as they realize that Smith is attempting to turn Neo into another clone of himself. Determined to live, Neo concentrated on the affected area, forcing the infection back towards Smith's hand. Neo then swiftly yanked himself free.
Immediately after freeing himself, two of the Smiths beside Neo grabbed onto his shoulders and Neo blocked against them and attacked them as well as another Smith behind him him and in front of him. After his swift physical defense, a fight between himself and the eight Smiths present was underway.
Neo fought many Smiths simultaneously and was able to hold out on his own for a while At best, Neo would momentarily stun them, and they would keep coming back for more and Neo would continue to defend himself well against them. Using many different forms of martial arts, Neo fought against them all. During the battle, more and more Smiths would eventually enter the scene and join the other clones in trying to defeat Neo. However, this would prove no match for Neo.
In the middle of the fight, a Bluepill entered the playground area and witnessed the battle taking place. However, she was soon possessed by Agent Thompson and he appeared within the entrance of the playground. Before he was able to join the Smith clones in fighting Neo, another Smith appeared next to him and pulled him away from walking toward the playground center.
Thompson recognized Smith and commented on his appearance with a surprised look. Smith was reluctant to see Thompson and immediately struck his hand into Thompson's chest and the same black fluid-like substance started to flow all around Thompson in a similar fashion like Neo before. After the substance fully covered Thompson for a few moments, the substance returned to Smith's hand and Thompson's appearance was revealed to be another Smith. After removing his hand, the newly appeared Smith and others soon appearing started walking towards the center of the playground and the fight continues.
Neo was still using many different maneuvers to defend himself. After being punched and knocked down by one of the Smith clones, Neo recovered and realized that many more were coming to join the fight by entering from the entrance doors and gates surrounding the playground. The Smith clones started to all attack Neo simultaneously and use judo techniques like grabbing Neo and throwing him to different areas of the playground. After being punched by one of the Smiths, Neo flew to the wall next to the swing and sandbox area of the playground, making a hole in the wall due to the impact.
After realizing that the Smiths may overcome him, Neo was able to grab hold of a tetherball pole from the ground as a weapon. Using it, Neo was able to engage the increasing numbers of Smiths pouring out from the apartments surrounding the playground. After hitting one Smith hard enough that he flew into the bench where The Oracle was once sitting on before, he commented on how more was on the way. Neo continued to battled with all the clones in the center of the playground with the tetherball pole until dozens of Smiths started to appear from the gates and door surrounding the playground and ran to the enter to fight with Neo until he he was surrounded.
During the fight, one of the Smiths attacked Neo and he lost his pole. Neo still continued to battle with the all the Smiths until he realized that there were too many for him to handle. Neo then started to jump on top of the Smiths and hop from one clone to another to reach another area of the playground where he can have more ground to handle them. But it was too late as after another Smith attacked him, Neo fell beck to the ground and then all the Smiths dogpiled on top of Neo.
Buried by all the Smiths, Neo struggled to break free. One of the Smiths within the piled clones told Neo he cannot win and all will be lost. Trinity, watching the battle, hoped Neo would break free. Upon hearing Smith's words, Neo regained his strength and pushed upward, sending all the Smiths flying to release him while holding the one Smith that threatened him. Neo threw that Smith into a group of Smiths standing, causing all of them to fall down.
After forcing all of them to break away from Neo, he realized that he has enough room to escape. Neo then bent down to charge up his flight ability and flew straight up into the sky, leaving the 50-some-odd total of Smiths behind.
After witnessing Neo fly away, Smith and his clones stared into the sky and they soon left the scene to return to Mega City to assimilate more copies to eventually try to rule the Matrix.
Upon reentering the Real World, Neo told the crew of the Nebuchadnezzar that when Smith tried to clone Neo by thrusting his hand into Neo's chest, it felt like he "was back in that hallway. It felt like dying." (By this, Neo is speaking of the hallway outside of Room 303 in the Heart O' The City Hotel, where he was shot to death by Smith before being resurrected as The One in the first film.)
Neo then told the others about what The Oracle said and their next objective to find The Merovingian and free The Keymaker as he will lead Neo to The Source and they will be closer to ending the Machine War.
