Speed: Massively FTL, Class F (she flew to the outer solar system and then the center oSpf the galaxy in seconds) See Nevermind's Sailor Moon Speed Calc -> http://www.narutoforums.com/blog.php?b=14992

Firepower: Sailor Moon at the end of the manga is a tier 4, Class C character. She was able to destroy the center of her galaxy, the Galaxy Cauldron, from which all stars are born in both her Eternal and Cosmos forms, giving her small galaxy level destructive capacity. Utilizing her Silver Crystal, she can both destroy enemies as well as heal and rejuvenate her allies as well as send people and souls through time. Several times in the manga she was shown to restore entire planets from ruin. She has been shown to be able to destroy intangible/immaterial enemies. In the end of the manga, she was shown to have control over every Sailor Crystal in the galaxy, and used this power (the Lambda energy) to defeat Chaos (for a time). She thus has a form of control over every power that the other Sailor Soldiers have shown. Utilizing the Cosmos Crystal and Lambda energy, she rebirthed an entire galaxy of Sailor Crystals. Sailor Cosmos (her future self) was shown to be able to create energy barriers, travel through time freely, and send the Sailor Quartet back to their proper time period, indicating a very high degree of time control (which would also be implied by Usagi's control over Sailor Pluto's Sailor Crystal in the last arc of the manga against Chaos). Her power was also felt throughout the universe as Neo-Queen Serenity.

Durability: High, possibly extending to planetary levels. While not even in Senshi form she stood next to Galaxia as she was destroying Tokyo with her energy alone in the Stars Arc. She stood up to attacks from Sailor Galaxia and fought Chaos inside the Galaxy Cauldron. She was also seen to not be harmed by Sailor Saturn's clash with Pharaoh 90 that caused worldwide devastation. It should be noted that Usagi is also functionally immortal. As long as the Galaxy Cauldron exists she will always be reborn after death. She can also survive in the vacuum of space. She can also survive for a limited amount of time with her soul ripped out as seen against Nehellenia, as well as resist having her energy drained.

Stamina: Very large. She flew to the center of the galaxy with no difficulty and did not look tired from her fights with Galaxia, her minions, and Chaos.

Intelligence: Varies. As Sailor Moon she is around an average teenage girl and was shown to be an academic underachiever, as well as lazy and a crybaby. She is very wise as Neo-Queen Serenity and Sailor Cosmos. She also displayed some extra sensory perception, psychometry, telepathy, and telekinesis enough to break through a floor.
