Their relationship could develop through shared experiences. For instance, if they both get trapped in a malfunctioning part of the Matrix. They have to rely on each other's skills. Neo's ability to manipulate the Matrix and Agent Smith's knowledge of its inner workings would be crucial. This would lead to a grudging respect between them.
In fanfiction, their relationship could be developed by exploring their similarities. They are both unique entities within the Matrix. Neo is the One, and Smith is the virus - like Agent. By delving into how they both are outliers in the system, they could start to understand each other on a deeper level. This could lead to a complex relationship that is part rivalry, part reluctant alliance.
One idea could be a scenario where Neo and Smith are forced to team up against a new, greater threat in the Matrix. Maybe a virus that is corrupting the code at a faster rate than Smith can assimilate it, and Neo's unique connection to the Source gives them a chance to stop it.
One idea could be that Agent Smith somehow gains a new form of consciousness and starts to have a strange alliance with Neo. They might work together to fight a new threat in the Matrix that is even more powerful than the machines. This would be a total role - reversal from their usual antagonistic relationship.
Neo's Path was a character from the Matrix. His moves were as follows:
1 Skynet: Use the "T" and "Space" keys on the keyboard to form a huge spider pattern and shoot a blue electric beam to deal damage to the enemy.
2. Berserk Attack: Use the "F" and "Space" keys on the keyboard to form a huge "F" pattern and shoot a red energy beam to deal a lot of damage to the enemy.
3. Time Deceleration: Use the "Q" and "Spacebar" keys on the keyboard to form a huge "Q" pattern and shoot a blue energy beam to slow down the enemy's time so that they can not attack or move.
4. Telepathy: Use the "E" and "Space" keys on the keyboard to form a huge "E" pattern and shoot a blue energy beam to read the enemy's mind information and control it.
5 Shadow Walk: Use the "W" and "Space" keys on the keyboard to form a huge "W" pattern and shoot a purple energy beam to quickly pass through the enemy and deal damage.
A common theme is redemption. Often, the female OC helps Neo find a new sense of purpose or redemption in his fight against the machines. For example, she might show him a different perspective on the Matrix world that he hadn't considered before.
One common theme is the exploration of power dynamics. Neo and Smith have very different types of power within the Matrix universe, and fanfiction often plays with how they interact and either compete or cooperate based on that power. For example, in some stories, Smith tries to overpower Neo using his ability to replicate, while Neo uses his connection to the Source.
One common theme is power struggle. Since Smith is a powerful character in the Matrix, when crossed over, there's often a battle for dominance. Another theme could be identity crisis. Smith might have to adapt to a new world or set of rules in the crossover, which challenges his sense of self.
She could start to see visions of the real world outside the Matrix that are different from what Neo saw. This leads her on a quest to find out if there's more to the real world than what she's been told. For example, she might suspect there are other hidden human colonies that are not part of the Zion she knows. Along the way, she has to deal with the doubt and suspicion of her fellow rebels who don't believe her visions.
One great Matrix OC Neo female fanfiction is 'The New Path of Neo and the Mysterious Girl'. It creates a really interesting OC who has unique powers and her interactions with Neo are full of tension and new possibilities.
