Summary
Powers and Stats
Tier: At least 2-C
Name: Sakuya Izayoi
Origin: Touhou Project
Gender: Female
Age: Unknown, likely very old (her abilities prevent her from aging)
Classification: Human
Powers and Abilities: Superhuman Physical Characteristics, Flight, Danmaku, Time Manipulation, Space Manipulation, Acausality, Alternate Timelines Awareness, 5 Dimensional Travel, Mass Manipulation, Resistance to mind-based abilities
Attack Potency: At least Multi-Universe level (Can create and manipulate timelines (we know she created the timeline and not just summoned a Sakuya from an existing timeline because the Sakuya wasn't surprised and did exactly what the former wanted her to, which would be impossible in a naturally created timeline as the Sakuya wouldn't expect to be summoned like that), is stated to have one of the strongest abilities for a human to possess , is overall considered as a strong character and should therefore not be so far from the likes of Miko, or Shinki, who created universes with an unknown number of timelines)
Speed: Immeasurable (Can move among a 5 dimensional axis, her 3D body is most likely not her true self as she was able to create enough energy to create a timeline)
Lifting Strength: Immeasurable
Sriking Strength: Immeasurable
Durability: Universe+ level to Multiverse+ level depending on the number of timelines the universe she's in have (since she can see what happens in other timelines and points in time, she can react to the death of a version of herself and do something about it, therefore, killing her require to erase her from every period of every timeline), can give herself "extra lives" by creating timelines
Stamina: Immeasurable
Range: At least Multi-Universe level
Standard Equipment: Knives, though she's mostly using them for playing rather than actually fighting
Intelligence Likely high (like most incident resolvers in Gensokyo)
Weaknesses: Is unable to properly reverse time and see the future in Touhou, however it's made clear to be more how time works than a restriction. Reversing time in Touhou will only move objects back to their former location without affecting their state, because the future isn't written and can't be overwritten. Since she's able to reverse time, though it doesn't have the effect it would have in another universe, she shouldn't have any problem with reversing time in a neutral universe where this rule doesn't apply.
