Akachi is a young adult who's been granted the power/ability to manifest impenetrable hard light projections anywhere. These hard light projections can be used as shields, weapons, armor, and even flying devices. There is no limit to what he can create and how he can use the hard light projections.
Being that he is the newest member of the X team along with his extraordinary abilities, he tends to not really care about what's going on around him. Having trained himself to reflexively project hard light in order to intercept any harm headed his way he is not only incredibly formidable but, an incredible offensive and defensive hero.
Although, he falters, in that he hasn't trained his body enough for hand to hand combat. So he can get exhausted in physical combat. Because of this he tends to take a step back and use projectiles when fighting.
Despite his aloof mentality when it comes to combat, Akachi has the potential to be the most powerful superhero the world has ever seen.
