Fucking wow

Superhuman Physical Characteristics,
Skilled Swordsman and Marksman,
Skilled Hand-to-Hand Combatant,
Statistics Amplification (Sword skills amplify the user's speed and power, with the downside of leaving some aftercast delay [Though Skill Connect negates this downside]),
Enhanced Senses (Via Hypersense and Distinguish),
Darkness Manipulation (via the Night Sky Sword),
Ice Manipulation (Can flash freeze a large area via the Blue Rose Sword. Can also create ice structures in general via Sacred Arts, such as when he created a five-layered ice shield),
Life Manipulation (Via the Blue Rose Sword [Continuously and passively saps the health of all those frozen] and Sacred Arts [Is able to restore something to its previous state]),
Light Manipulation (Via the Night Sky Sword [Absorbed a light-based attack from Fanatio] and Sacred Arts),
Plant Manipulation (Via the Night Sky Sword),
Transmutation (via the Night Sky Sword. Turned PoH into a tree),
Energy Manipulation (Via the Night Sky Sword. Able to absorb "Resources" (energy) within a far-reaching range. This includes stars), Magic & Creation (via Sacred Arts. Can create a spell or an object for almost any situation, so long as he knows the words used to arrange his thoughts, guide his emotions, and fuel his imagination to create said spell or object),
Poison Negation (via Sacred Arts),
Heat Manipulation (via Sacred Arts),
Healing (via Sacred Arts),
Elemental Manipulation (via Sacred Arts. Can create dozens of elements or elemental objects of all kinds),
Homing Attacks (via Sacred Arts. Can make his attacks home in on enemies),
Limited Reality Warping (via Incarnation. Allows the user to change the world to an extent via their willpower or imagination. For those who are not conscious or adept with this ability, it is primarily used to increase the chances of winning a fight against stronger opponents or create miracles not possible with standard Sacred Arts. For Kirito, it allows him to increase the range of his attacks, transform into his SAO Avatar, and create giant black wings to fly. All virtual avatars are capable of Incarnation, however only those who recognize this ability can consciously use it to their advantage),
Barrier Creation (via Incarnation. Can create "imagination barriers" from his mind to block attacks, as well as barriers of light), Regeneration (Mid via Incarnation. Regenerated his severed arm without him noticing, comparable to Quinella),
Immortality (Lived for over 200 years in the Underworld alongside Asuna. Should be the same as Quinella, as Star King Kirito meant to eternally rule the Underworld) and Self-Sustenance (Types 1 and 2. Can survive without oxygen in the depths of space, and is also comparable to Quinella). Should also have all of Quinella's abilities, as he grew stronger within those 200 years while Quinella remained stagnant.
