A unique character could have a different way of controlling the Juggernaut Drive compared to the canon characters. Maybe they can use it in short bursts without losing their sanity, which would be a very interesting twist.
You can give the character a unique backstory related to the Juggernaut Drive. For instance, if they were an experiment gone wrong and that's how they got the power. This would make them stand out.
Create a character who is not initially interested in the power of Juggernaut Drive but is forced to use it for the greater good. Their reluctance and then their growth as they learn to handle the power can make for a very unique and engaging character in the fanfiction.
One idea could be exploring the psychological effects on the character who activates Juggernaut Drive. They might struggle with the newfound power and the loss of control. For example, they could have internal battles between their normal self and the more aggressive, power - hungry side that the Juggernaut Drive brings out.
One popular 'Highschool DxD Issei Juggernaut Drive' fanfiction is 'The Red Dragon's Ascent'.

Power - up themes are common. The Juggernaut is a very powerful entity in the Highschool DxD universe in fanfictions. So often the stories revolve around the protagonist either obtaining Juggernaut - like powers or using Juggernaut powers in new and exciting ways.
First, think about the heritage. Decide which Highschool DxD character their ancestor is. Then, consider how that heritage would manifest in the descendant. For example, if the ancestor was a powerful devil, the descendant might have a natural affinity for dark magic. Second, give them a unique personality. Don't just make them a copy of their ancestor. Maybe the descendant is more timid or more rebellious. Third, think about their goals. Are they trying to live up to their ancestor's name or break free from the shadow?
First, give your OC a clear backstory. For example, if it's a hybrid of a devil and a werewolf, explain how this came to be. Was it an experiment? Or a forbidden love? Then, focus on their personality traits. Maybe they're conflicted because of their two natures, like being hot - tempered like a werewolf but sly like a devil. Also, don't forget to give them unique physical features, like glowing eyes or sharp claws.
A believable self - insert should have goals and motivations that fit within the Highschool DxD universe. If they are interested in getting stronger, show how they train and struggle to achieve that.

Don't make them all - powerful right away, let them grow and develop as the story progresses.
To create a believable main character in Highschool DxD reincarnation fanfiction, start with giving them a clear motivation. For example, if they were bullied in their previous life and now have power, they want to stop bullying in the devil world. Their reactions to new situations should be consistent with their past experiences and personality.
Give the OC a distinct gaming style. For example, if they are a stealth - based gamer in the real world, they could transfer that into the DxD world by having the ability to use magic to become invisible or move silently. This would make them stand out.
Think about the backstories. A character could be a half - breed, born from a Nasuverse mage and a Highschool DxD devil. Their upbringing in two different worlds would shape their personality and abilities in a very unique way. They might struggle with their identity, which could be a great source of character development.
