There was a moment when Pain was giving a serious speech to the other Akatsuki members about their goals. Just then, Zetsu popped up out of nowhere and said something completely off - topic, like 'I just saw a really big bug'. Everyone was so shocked by his random comment that they all burst out laughing, including Pain who couldn't keep his serious face any longer.
In many 'naruto fights akatsuki fanfic', one of the best moments is when Naruto first uses a new jutsu against an Akatsuki member. It's a moment of great surprise and power.
There was a school play where an actor forgot his lines. Instead of panicking, he started making up the most hilarious lines on the spot. The whole audience was in stitches. It was a great example of how mistakes can turn into something really funny at school.
One funny Akatsuki story could be about Deidara and his explosive art. Once, he was trying to show off a new type of explosive to Sasori, but it backfired and ended up blowing up his own hair. He looked like a porcupine for a while, which made Sasori laugh, a rare sight indeed.
One funny Akatsuki fanfiction story could be about Hidan and Kakuzu's constant bickering. Hidan, being his crazy self, decides to play a prank on Kakuzu by 'hiding' his money bags. When Kakuzu finds out, he chases Hidan all around their hideout, with Hidan laughing hysterically while Kakuzu is fuming. It's a humorous take on their odd relationship within the Akatsuki.
In a fanfiction, the Akatsuki members decided to have a talent show. Deidara thought his art was the best talent and started showing off his explosive sculptures. But then Tobi got up and did a really goofy dance that had everyone laughing, including Sasori who usually never shows any emotion. It was so unexpected that even Itachi cracked a small smile.
The personalities of the Akatsuki members. For instance, Hidan's over - the - top religious fanaticism combined with his impulsiveness can lead to really funny situations. Like when he challenges someone to a fight without thinking about the consequences.
Naruto could use his shadow clone jutsu to play pranks. For instance, he could make clones that look like the Akatsuki members themselves and have them do really silly things like dance around in circles or sing out - of - tune. The real Akatsuki members would be really confused at first, thinking one of their comrades has gone crazy.
Maybe the story is that Sakura accidentally gets involved in an Akatsuki mission. She tries to play along to avoid trouble and ends up making the whole situation really comical. Like she uses her medical skills in really strange and unexpected ways during their heist, causing the Akatsuki members to be both confused and amused.
One interesting fanfiction is when the Akatsuki attempts to make a music video for recruitment purposes. Deidara is in charge of the special effects, which end up being more like explosions. Kisame is made to sing, but his deep voice makes it sound like he's growling rather than singing. Konan tries to choreograph the dance, but everyone has their own ideas and it turns into a chaotic mess. This shows the Akatsuki in a completely different and humorous light.
