RIAS GREMORY (Highschool DxD)
Powers and Abilities
Demonic Power: Rias has exceptional demonic power even for a High-Class Devil. Azazel has noted that even without training, she has the potential to become a Devil of the highest class relying solely on natural talent alone. Upon utilizing her demonic power of destruction, the surroundings will gradually shake to where her abilities are comparable to an Ultimate-Class Devil.
Power Of Destruction: A unique form of demonic power that allows her to release energies that can disintegrate matter, both living and inanimate, with relative ease. She is further able to control the shape and power of the technique such as creating multiple softball-sized bullets to lessen the destructive force yet increase the range of her attack.
Extinguished Star: Rias' ultimate one-hit kill technique made due to the change in her demonic power due to the influence of Issei's power. She manipulates her Power of Destruction into a compression of an unimaginable amount of demonic power; takes on the form of an enormous sphere with a mixture of crimson and black aura radiating from it that moves toward her enemies at slow speeds. The Extinguished Star has a strong magnetic force, which pulls enemies towards it and is disintegrated similar to a black hole. Its destructive power has been stated to surpass the speed of the retiring system in the Rating Game.
Castling: Due to being the King of her own peerage, Rias has the ability to use Castling, which allows her to swap locations with one of her Rooks. She first used it during Nilrem's attack on Kuoh Academy, swapping places with one of her unused Rook pieces.
Expert Magician: Rias is also shown to be proficient in using magic such as the ritual to drain the dragon aura from Issei's left hand to let it appear human again, teleportation magic, healing spells, defensive magic to protect herself and her servants from powerful attacks, and create several layers of defensive barriers to protect from the explosive aftershock of Katerea self-destruct spell. Rias can also use magic communication circles.
Healing: Rias is capable of healing others using her magic aura, this usually requires her embracing the injured person and both parties to be completely nude in skin to skin contact for better effectiveness. She has shown to be able to heal fatal wounds such as when Issei was struck by a Light Weapon.
Enhanced Durability: Rias has shown great tolerance to damage and pain, she was going to continue to fight Regulus and remain in the Rating Game despite the intense blood loss.

FEATS

Rias is considerably skilled in using magic and demonic energy, and is regarded to be so talented that she can reach the highest grade of devils without any sort of training. As an Ultimate-class Devil, she is superior to High-class Devils such as Balance Breaker Issei.
MOKA AKASHIYA (Rosario + Vampire)
Powers and Abilities
Vampirism: When the rosary is taken off Moka's neck, she becomes faster, stronger and more durable than Outer Moka. She also becomes much more willing to fight due to her upbringing, and will take on anyone willing to face her. Inner Moka has immense strength, being able to knock out most monsters with a single kick. In her unsealed state, Moka possesses super strength, super speed, incredibly agile reflexes and regenerative properties.
Yokai Detection: In her unsealed state, Moka can detect the presence of other monsters by sensing the demonic aura around them, helping her to find hidden enemies. This works similar to a bat's echolocation, except she waits to sense her opponent's aura rather than send out a pulse on her own and then receive the returning pulse.
Immense Strength: As a vampire, Moka is extremely strong. When Moka kicks an enemy, they will be sent flying and gain a huge injury and the place where the enemy flew and landed will also receive enormous damage.
Immense Speed: She is capable of running and accelerating to high speeds which a human and many other monsters could never achieve.
Immense Stamina: Moka's musculature produces considerably less fatigue toxins during physical activity than the musculature of an ordinary human. She can physically exert herself at peak capacity for hours before fatigue begins to impair her.
Immense Durability: The tissues of her body are considerably harder and more resistant to physical injury than those of an ordinary human or monster. Moka is capable of withstanding great impact forces, and falls from great heights, without sustaining any injury.
Enhanced Agility: Moka's agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete or any other kind of monster.
Enhanced Reflexes: Her reflexes are heightened in a similar manner and are superior to those of the finest human athlete or monster.
Shinso Bloodline: Moka has inherited the blood of a Shinso from her mother Akasha, granting her a legendary power that is far greater than any average vampire. The blood was given to her from birth, causing Moka's features to change to the characteristics of the legendary vampire.
Immense Demonic Aura: When she activates her Shinso blood whether intentionally or not she emits a powerful aura that is described as "a darkness deeper than night". Her Shinso blood also radiates a much darker, more potent aura than the usual vampire blood and given a vampire's "aura conversion" ability, this allows for an exponential increase in the amount of power they can generate.
Expert Hand-to-Hand Combatant: Moka's main method of attacking is Tae Kwon Do by using kicks. Therefore, she has a lot of variation with her kicks. Her attacks are essentially intense bursts of concussive, strength released in one kick. The result of getting kicked is devastating. Even a strong opponent will be sent flying away and usually sustain a crippling injury. Despite her fighting nature as a vampire, she does not truly wish to kill anyone since she has a soft side and she is merciful.
Keen Intellect: Despite Moka's fighting nature, she has proven herself to be very intelligent as she is capable of deducing the nature of her opponents and their tactics through either a mere glance or after a few short blows.
FEATS
During the 1st and 2nd Seasons of Rosario Vampire, every monster that Inner Moka came across, she was able to defeat most if not all of them with a single strike, showcasing her incredible power. Those she didn't beat with one strike she still bested with relative ease.
She is an expert martial artist and an excellent student. Yukari, who ranked 1st in the intelligence section at the school, praised Inner Moka. (To explain Yukari's intelligence, she made a technological device and its feature was to change minds, she has inventions like this.)
