Wall Level: Mooncats like Luna and Artemis can jump multiple stories. Admittingly haven't calced this one but I am guessing it would probably be something like wall level.
Scales to: Basically everyone. Artemis needed Minako to even fight weak Dark Agency Agents, wasn't like he was able to do anything against them alone. I'd guess, though I can't be certain it'd scale to like the random spirits and vampires running around as well. I mean Mrs. Hubert the vampire was able to at least survive a Sailor V kick so I'd give a guess that everyone who has powers at all scales to at least this.
Building Level: Devleene was able to maintain a building with her presence. A Genius Loci Spirit does the same in Chibiusa's picture diaries
Scales to: I have to guess it would be almost everyone. The spirits are never presented as being any kind of major threats with obvious exceptions. And it's not like Devleene was some high tier Dark Agency Member. Her job was literally to provide sweets and tea to Danburite.
Town Level: Electric Fighter Luuga created a dimension extending to the horizon. Sailor Mars destroyed a similar dimension with her first attack. Sailor V’s ultimate attack is “Love Megaton Shower”
Scales to: So Luuga is actually implied to be a major Dark Agency Member, though that still means she was way below Partially Awoken Sailor Venus, aka Sailor V. Honestly I want to guess the Youma were above her considering Morga was able to survive an attack, if a not very serious one, from Partially Awoken Moon and Sailor V was beating up Luuga in her own dimension while Amano controlled her. At the very least it easily scales to Shitennou and to people above them.
Country Level: Zoisite created a heavy storm that covered all of Japan for many days
Scales to: Probably at least to the other Shitennou Jadeite and Nephrite (though Kunzite didn't need it). Might just be dc and not dura though. This might scale to partially awoken Senshi considering Zoisite knew his power paled in comparison to Mars'
Multi-Continent Level: Kunzite shifted the Earth so that Tokyo would be the North Pole
Scales to: So does it downscale to anyone stronger then him? Not really. You could scale it to Fully Awoken Senshi if you don't think they scale to Base Princess Serenity but beyond that anyone who would scale to it from above scales to better anyway. What about upscaling? Is there anyone close enough to him in power that they should basically have his stats.....ehhhhhhhhhhh I can make a solid argument the Partially Awoken Senshi weren't that much weaker then their fully awoken counterparts based on how fully awaking, meaning getting their memories back doesn't mean much when then Silver Millenium counterparts were implied to be weaker from a living a life of eternal peace and how the other Shitennou really shouldn't be that weaker then Kunzite logically but it's still a stretch so.......idk
Stellar Level: Using the Ginzhuisho could blow apart a star casually and was compared to a supernova. A huge number of people survive inside Nemesis said to a black hole as well as the end of spacetime
Scales to: Upper Tiers of the First Arc, and a lot of people in the Second Arc Scale to this since Baseline Princess Serenity who tanked her own energy output would be weaker then First Arc Sailor Moon and it's implied that baseline Usagi after becoming Queen of the Moon had the same level of power as First Arc Sailor Moon.
Solar System+ to Low Galactic: Planet Nemesis was supposedly a Black Hole, capable of enveloping the star system and whole explosion in the sky was the size of the sun despite being past the orbit of Pluto and was calculated to be in the KiloFoe to MegaFoe range, a low galactic feat. Chibi-Usa destroys two “weaver stars” in one attack though they were in human form. Princess Snow Kaguya created a nebula.
Scales to: Second Arc Sailor Moon and Chibi-Moon did the first feat using "Moon Princess Halation" however by the Third Arc to fight the Daimon Sailor Moon had to draw down more power from Neo-Queen Serenity after the powerup she had already gotten in order to use "Moon Spiral Heart Attack" heavily suggesting that Moon Princess Halation wouldn't have killed the Daimon. This basically means it scales to everyone from the Third Arc and on that is even remotely on par with the Senshi.
Galactic+: Pharaoh 90 warped spacetime from a “distant galaxy”. Pharaoh 90 moves a galaxy at mftl speeds. Pharaoh 90 created a galactic sized wormhole. Sailor Saturn brought oblivion onto Pharaoh 90’s galactic+ sized dimension. The Silver Crystal lighting up the universe at the end of the Fourth Arc
Scales To: Super Sailor Moon's HENSHIN was "tens of thousands" of times stronger then the power of Pharaoh 90 and crew. I know Super Sailor Moon isn't the weakest Super Sailor Senshi but I'd be hard pressed to imagine that any of the other Super Senshi aren't at least as strong as her HENSHIN. Outside of this almost no one. There are no manga villains on the Super Senshi's levels. Pharaoh 90 has galactic feats but his power is still way below Super Sailor Moon and he wouldn't been doomed if his energy absorption allowed him to basically tank her attacks. The fourth arc villains are mostly goofy joke villains who clearly don't scale and all the fifth arc villains are Eternal Senshi Level.
Universal: The Silver Crystal numerous times warping all of spacetime, and is the source of all energy. The Silver Crystal creating more chaos in spacetime then had ever existed. Princess Snow Kaguya can freeze a universe. The Poison Black Crystal warping all of spacetime. Nehelenia maintained a universe. The Silver Crystal can create a universe. Chaos warping all of spacetime with it’s presence. Lambda Power reset the cosmos.
Scales to: Nehelenia maintaining a universe is most often used to justify basically everyone in Fifth Arc being Universal since Civilian Form Usagi was tanking Civilian Form Galaxia's power said to be way above any of her previous villains and from there everyone scales to at least Civilian Form Usagi. The strongest crystals of the universe tend to cluster around this "warp all of spacetime" levels which is especially pertinent because spacetime are said to be the distortions of energy and will.
1: Luna and Artemis rapidly travel from Earth to Moon. Luna does it again when turned into humanoid form. (Massively Hypersonic)
Scales to: So this one is a bit weird. The Mooncats have the power to briefly channel the powers of their partners so it could be argued this was just that and not of their own volition, that said whenever they have done that it wasn't in terms of speed, it was them releasing large bursts of energy. Likewise Luna was able to do it in her humanoid form. This theoretically could scale to anyone with powers in the verse
2: Minako releasing a burst of latent planet power sends her to Venus (Relativistic to FTL):
Scales to: This was Minako before even transforming for the first time. Honestly you very well could argue this should scale to anyone in the verse, though conservatively speaking it scales to anyone at least as strong as the Partially Awoken Sailor Senshi.
3: Hotaru in civilian form travels to Charon Castle orbiting Pluto in seconds (FTL to MFTL):
Scales to: Not sure honestly....how the fifth arc civilian form senshi scale to anyone in the prior arcs?
4: Weaver Stars travel a distance of thousands of lightyears ever year casually (MFTL)
Scales to: The Stars act as the civilians of the SM Universe Proper. The civilians are the beings that inhabit the universe. This is again tricky, but at the very least Metalia should scale, as well as The First Arc Senshi, which likely means scaling to everyone in the Second Arc.
5: Prince Diamond can conquer all the planets in space in a natural lifespan (MFTL)
Scales to: Prince Diamond was pretty fast within the context of the Second Arc, considering he blitzed Black Lady. I'd argue he at least scales to the stronger entities of the Third Arc but eh, it's hard to tell.
6: Princess Snow Kaguya was going to freeze the universe
Scales to: At least Super Sailor Moon, and from her to probably most of the Super Sailor Senshi since Super Sailor Moon was the one who beat her.
7: Eternal Sailor Senshi travel a galactic distance in seconds repeatedly
Scales to: Basically everyone notable in the Fifth Arc was Eternal Senshi level and Eternal Senshi were able to zip to and from the center of the galaxy almost instantly including low tier Eternal Senshi. Casually.
8: The Silver Crystal’s light travels to the edge of spacetime in seconds
Scales to: Unknown...Kaguya and Nehelenia have both reacted to the light of the Silver Crystal in motion so likely to Eternal Senshi level entities
9: The Lambda power travels across the universe in seconds
Scales to: The Eternal Amazon Senshi seemed to be moving around while the stars sent by the Lambda Power were still at the Galaxy Cauldron which at most is the size of the center of the galaxy. Everyone Eternal Level or up would scale.
Sailor Moon Classic:
Let me first say that their is a fairly consistent track you can use ignoring the universal feats, and then you have the universal feats that jack it up.
Large Building Level: In Sailor Moon and Kunzite’s Battle, the other Senshi unconscious from battle tank the explosion of a dimension that was the size of a tower and made of negative energy, which seemed to make it harder to destroy
Scales to: Probably anyone significant lol. I mean if the Senshi can tank it unconscious then surely to actually damage them unconscious would require at least this level of power
MCB to Town Level: Kigaan maintained a sizeable dimension, as does Ramua. The DD Girls and Senshi can survive the heat of magma, Droid Furaiki can create a thunderstorm across Tokyo, Droid Nipasu can create a snowstorm across Thunderstorm.
Scales to: High End Monsters of the Week for first two seasons. Minibosses of first season
Country Level+: Sailor Moon despite dying, survives the energy of the Silver Crystal’s creating a country sized explosion across the Earth. Death Phantom’s Casual Power was going to lifewipe the Earth
Scales to: Second Arc Senshi should be at least here considering they survived Death Phantom's Casual Power and are likely stronger then first arc Sailor Moon. Second Arc Minibossess probably here.
Continent Level: Either Queen Beryl and Queen Metalia causes sun spots and disasters across the Earth.
Scales to: Prince Endymion one-shot Queen Beryl. If it was Beryl, then second Arc Senshi should likely be here via scaling to him.
Planet Level: The Silver Crystal is described as having the power to destroy a planet. The Makaiju and the Xenian Blossom have the capacity to destroy planets, seemingly violently (and tank their own power) yet their power pales compared to the Silver Crystal. Usagi's dying wish on the Silver Crystal reality-warping the Earth.
Scales to: The First Daimon in S overpowered the power the prior Silver Crystal State, despite being not even a combat Daimon, suggesting that Daimon should be here. This suggested that the training the Guardian Senshi do in S make them jump from country-continent to planet level. Third Arc Minibosses should be least here, as would the Outer Senshi by scaling necessity.
Stellar Level: The Golden Crystal has the power to destroy the stars, yet the Super Senshi survive the Golden Crystal’s explosion. Super Sailor Moon and Super Sailor Chibi-Moon destroy Queen Badiyanu’s Black Dream Hole.
Scales to: Super S scaling is really weird. The AMAZONESS QUARTET survive the power of the Golden Crystal which just....doesn't make ANY sense whatsoever. Freaking comedy season. That said it should be good for the Super Senshi and for most of the people in Stars since the Super Senshi would likely be as strong or stronger later.
Multi-Stellar Level: Sailor Galaxia fights Sailor Starlights across the galaxy creating numerous explosions larger then solar systems
Scales to: The Starlights were rivals to the Outer Senshi so it probably scales to the Super Outer Senshi.
Galaxy Level: Chaos engulfs a galaxy in darkness, Angel Usagi’s light illuminates the galaxy. Sailor Galaxia’s dimension seemingly contains inter-galactic space
Scales to: The Top Tiers; Kakyuu, Usagi, Galaxia, Chaos.
That said if you want to boost people we consider the myriad universal feats as legit
Universe Level: Super-Beryl claims to be able to destroy the universe. Death Phantom is said to be going to turn the universe into nothingness. Ikasaman was merging and warping "countless" dimensions. Pharaoh 90 is a living universe bigger then the real one that was destroyed in one blast by Sailor Saturn that Super Sailor Moon survived within the center of. Sailor Galaxia is said to be a threat to the universe.Scales to: If you accept this conservatively, then Super Senshi level entities considering Super Sailor Moon surived the destruction of one of these entities. More liberally anyone Princess Tier or above, which means basically everyone second arc and later.
1: Luna and Artemis run from Tokyo to the North Pole in minutes (Hypersonic)
Scales to: Everyone with powers. The Mooncats are fodder.
2: Fodder Human Soldiers quickly go from the Earth to the Moon (Massively Hypersonic)
Scales to: Likely Everyone with powers
3: Sailor Moon early in the series outpaces a flash of light from a camera many times (FTL)
Scales to: At least high tier Monsters of the week even in season 1. Every miniboss.
4: The Maikaiju can wander the universe (MFTL)
Scales to: The Second Arc Senshi can perfectly fine react to Maikaiju's movements, suggesting at least Second Arc Senshi and Minibosses and up.
5: Fiore before finding the Xenian Flower was able to search hundreds of planets for a flower to present to Mamoru
Scales to: Second Arc Sailor Moon was able to keep up with Xenian Fiore, who should be equal or stronger then Base Fiore, suggesting it scales to Second Arc Moon, and from her likely to the strongest second arc entities and to anyone with powers in the later arcs.
6: Usagi’s Cosmic Moon Power against Pharaoh 90 traveled inter-galactic space
Scales to: Arguable. I guess Pharaoh 90 was moving comparable to it, but Pharaoh 90 also doesn't scale to anyone in particular.
7: Sailor Saturn and Super Sailor Moon fly to the center of a living universe in secondsScales to: At least Super Sailor Level Entities, meaning basically Fifth Arc Entities. Super S movie implied Base Outer Senshi were stronger then Super Guardian Senshi, which you use it so scale to everyone in third arc and onward possibly
Might make a part 2 with other canons. If I do Sera Myu, you'll see why I call it the most insane canon of Sailor Moon.
