In this fanfiction, Barry might have some amazing speed - related adventures with the Justice League. Maybe he shows off his super - speed to the other members in a training session and impresses them all.
One great story could be where Flash has to outwit Rogue's power-absorbing abilities in a unique way. Maybe he uses his super speed to create distractions that prevent Rogue from getting close enough to touch him and absorb his powers. This creates an interesting dynamic as Rogue is constantly trying to find a way to get the upper hand.
One possible plot could be that Naruto is somehow transported to the DC universe and meets Diana. They might initially be at odds due to their different fighting styles and values. Naruto, with his ninja skills and never - give - up attitude, could start to earn Diana's respect as they face a common enemy, perhaps a powerful villain who is threatening both the ninja world and the Justice League's world. They could combine their powers, Naruto's Rasengan and Diana's Lasso of Truth, for example, to defeat the foe.
Obviously, Barry is one of the main characters. And then the members of the Justice League like Superman, Batman, Wonder Woman, etc. are also main characters as it's about Barry meeting them.
Well, there could be an epic battle. Maybe the Justice League is facing a powerful enemy and Barry Allen, with his super - speed, arrives just in time to turn the tide. He could use his speed to disrupt the enemy's attacks and create opportunities for the other members of the Justice League to strike.
The 'New 52' Justice League origin story is also great. It brings together the classic heroes like Superman, Batman, Wonder Woman, etc. for the first time in this new continuity. We get to see how they initially interact, their distrust for one another at first, and how they gradually form the iconic Justice League. It's full of action and great character development.
One interesting story could be where the reader has a unique power and gets recruited by the Justice League. They then go on adventures together, facing powerful villains. For example, the reader might have the power to manipulate time, which helps the League in a battle against a time - traveling foe.
Naruto's chakra - based powers like the Rasengan could be combined with Diana's superhuman strength. For example, Naruto could create a Rasengan and Diana could use her strength to throw it at an enemy with even more force.
