Definitely Naruto himself. His energetic and positive personality would bring a lot of life to the chat. And Sasuke too. His brooding nature would create some interesting contrasts.
In a 'naruto group chat fanfiction', Orochimaru could be an extremely interesting character to include. His devious and intelligent mind would make the chat full of mystery and intrigue. Also, Gaara. His past experiences of being an outcast and then finding his place in the world would give him a unique perspective to share. And Shikamaru, with his lazy - but - actually - really - smart personality, would be able to come up with some clever remarks and strategies within the chat.
I think Kakashi would be a great addition. With his laid - back yet wise attitude, he could provide some really good insights and also some humorous comments. Jiraiya would also be interesting. His pervy nature might lead to some comical moments in the group chat, and his knowledge of the ninja world is vast. And of course, Hinata. Her shy yet strong - willed personality would add a different dynamic, especially when interacting with Naruto.
Definitely Deku. His naivete and eagerness to learn would make for some really cute and funny group chat interactions. Bakugo would also be great. His hot - headedness and tendency to yell (even in a chat) would add a lot of drama. And All Might, he could be like the wise old mentor who drops in to give inspiring messages from time to time.
One idea could be a group chat where Naruto, Sasuke, and Sakura discuss their future dreams after the war. Another could be a chat where all the different ninja clans come together to plan a joint mission through a group chat.
The Sage of Six Paths could be included. As he is the originator of many ninja powers, his connection to Amaterasu could be explored. Maybe he had a hand in creating or containing the power. His presence in the fanfiction would raise the stakes and give a more epic feel. Additionally, Hinata could be in the story. Her love for Naruto could play a role, for example, if Naruto is in danger because of Amaterasu, Hinata could try to save him in her own way.
Sasuke is a great character to include. His cool and brooding personality can create interesting dynamics in crossovers. For example, if he crosses over into the world of Attack on Titan, his skills as a ninja would be put to the test against the Titans. Another interesting character is Kakashi. His laid - back yet highly skilled nature can add humor and action to crossovers. He could be a great addition in a crossover with the world of Inuyasha, sharing his knowledge of combat and jutsu.
Well, one interesting scenario could be when the characters from Naruto start sharing their most embarrassing training moments in the group chat. It would be hilarious to see Naruto talk about how he accidentally blew up his own clone during a jutsu practice.
The interactions between the characters. We get to see their different personalities shine through in a chat setting.
Sasuke is also very popular. His brooding nature and his powerful skills create an interesting dynamic. Fans love to see him engage in debates or share his insights on different ninja techniques in the group chat.
One interesting storyline could be the Pokémon themselves having a group chat to plan a surprise party for their trainers. They secretly communicate about getting the right gifts, like a Pikachu finding a rare Thunder Stone for its trainer who wants to evolve it further.
Another storyline could involve them using the group chat to plan a surprise party for one of their friends at Beacon Academy. They'd discuss decorations, food, and how to keep it a secret. There could be some comical moments when things almost go wrong during the planning process.
I think Kakashi from Naruto would be really cool in a fanfiction with Asura's Wrath. His calm and collected nature, along with his Sharingan abilities, could provide some strategic advantages in battles against the powerful foes from Asura's Wrath. Also, Yasha from Asura's Wrath with his loyalty to Asura and his combat experience would be a great character to include for some intense action scenes.
