Characters with the ability to use one - handed seals may be seen as more powerful or advanced. This could lead to new rivalries or alliances. In battles, other ninjas might be more cautious around them, or seek to learn the technique themselves. It could also lead to a shift in the overall power structure within the ninja villages as those who can use one - handed seals gain more influence.
One - handed seals might allow for more complex jutsu combinations. Since the hands are freer, a ninja could potentially chain together different jutsu more seamlessly. For example, a fire - style jutsu followed immediately by a wind - style jutsu to enhance the attack. This would change the power dynamics as it gives the user more versatility in combat.
One interesting concept could be a story where Naruto discovers he can perform one - handed seals more effectively than two - handed ones. This gives him an edge in battle, allowing for quicker jutsu activation. For example, he might be able to surprise his opponents who are used to the normal two - handed seal - casting time.
There is a possibility that it was an ex - shinobi who had retired from active duty. This person had amassed a collection of seals during their career and now made a living by selling them to other ninjas like Naruto.
Well, in some fanfictions, memory seals can be hierarchical. There could be a main seal that controls access to a set of smaller, more specific memory seals. For example, a character might have a top - level seal that guards their entire past, and within that, there are smaller seals on specific events or people. To access a particular memory, one would need to break through the relevant sub - seal first. This makes the process of uncovering memories more complex and interesting.
The chakra guns can introduce a new level of strategy. If a character has a chakra gun that can fire different types of chakra - based ammunition, they can choose which type to use depending on the opponent. For instance, against a water - style user, they might use a lightning - charged bullet from the chakra gun to counter their jutsu. Also, it can change the power balance. A relatively weak ninja with a powerful chakra gun can hold their own against stronger opponents.
Well, considering Naruto's own experiences and the variety of seals in the Naruto universe, he could sell communication seals. These would allow ninjas to send messages over long distances. He might also sell seals that are related to elemental jutsu, perhaps ones that enhance or modify fire, water, wind, earth or lightning techniques.
Perhaps Naruto was in a situation where he had made a deal. For example, he promised to pay for the seals in exchange for some information about a missing nin or a secret technique. He values knowledge and power, and if paying for the seals was part of getting closer to achieving his goals, he would do it.
It can also be used defensively. The chakra arm can block attacks more effectively than a normal arm because it can be infused with chakra to make it stronger. So, opponents might need to find new strategies to break through this defense. Moreover, if the chakra arm has unique abilities like energy blasts, it can force enemies to keep their distance, completely altering the usual close - range combat scenarios in Naruto battles.
If the 'All for One' ability was introduced in Naruto fanfiction, it would completely disrupt the power dynamics. For example, a character with this ability could potentially steal the powers of the Kage - level shinobi. This would make that character extremely powerful overnight, and the balance of power between the villages would be severely affected. They could then use these stolen powers to either rule over others or cause chaos.
Fanfiction writers may also use the seals as a way to connect Naruto to other elements in the Naruto universe or even to other fictional universes. For example, the seals could be a link to a different dimension where there are new challenges and allies for Naruto. This allows for crossovers and unique story developments.
The seals could also be a plot device for a darker storyline. Maybe they were placed by an unknown enemy to control Naruto or use him as a weapon. In some fanfictions, the seals start to affect Naruto's mental state, causing him to have inner struggles between his normal self and the influence of the seals.
