>According to this: https://vsbattles.fandom.com/wiki/User_blog:LordGriffin1000/Dorathea%27s_Cloud_Split_Redux

>Dorathea was powerful enough to part the clouds with a force of 136 Zettatons combining both the KE and RKE calcs

>Which is planet level, with the multiplier of 100 from the Ecto-skeleton that would be around 14  Yottatons of force

-Maximum output of the Ghostly Wail

>Danny's Ghostly Wail was powerful enough to one shot Dan Phantom who's basically Danny Phantom gone bad

>Since Dan Phantom is the most powerful ghost Danny faced which makes him more powerful than the Ancient Ghosts who defeated Pariah Dark with his crown and ring on hand

>According to Vlad from the future, when his ghost half and Danny's ghost half got removed they were fused together and formed Dan Phantom. Since Wulf was strong enough to overpower Danny back in Season 1 and in Season 3 there were wanted posters of Wulf along with Undergrowth and Vortex and the posters have a bounty of 1M, 2M, and 3M. 

>136 x 2 x 2 x 3 x 29 x 100 x 100 x 6 = 28,396,800 zettatons or 3 Tenatons(Dwarf Star Level) x 100 = 300 tenatons(Star level)

>According to this: https://vsbattles.fandom.com/wiki/User_blog:LordGriffin1000/Pariah_Dark_travels_the_Ghost_Zone

>Pariah can move at speeds of 1041003870728 mph or 1552x speed of light, since Danny was 10x slower than Pariah at the time, he can still move at speeds of 155.2x faster than light with the Ecto-Skeleton

-Scaling to Vlad

But when Ryuko was not up to Ragyo's standards she threw her away like garbage and her husband Soichiro didn't really like that so he took Ryuko to himself and changed his identity to Isshin Matoi and raised Ryuko himself. She didn't have the best childhood with her dad and she was sent to boarding school and then one night Nui Harime murdered Ryuko's father and took half of her signature weapon the scissor blade. She went on a quest to find her father's killer and avenger her father. And with a Kamui named Senkestu and a scissor blade she can take out her father's killer no problem.

Stats(Strength and Durability):

https://youtu.be/aNo-wo6sPy4

-Ryuko's full power without Senketsu

>At the end of the series, Ryuko was strong enough to destroy the SS Naked Sun and Honnouji Academy Final Defense Apparatus without Senketsu

>According to this: https://vsbattles.fandom.com/wiki/User_blog:Migue79/Kill_la_Kill:_S.S_Naked_Sun_Durability

>Ryuko is more powerful than Satsuki (after Junketsu absorbed Ryuko's blood), Ragyo (in Base and Shinra Koketsu without merging with the OG Life Fiber) and the Elite Four with their strongest versions of their Goku Uniforms, and merged with the OG Life Fiber

>SS Naked Sun is durable enough to unleash a force of 2 Petatons, since Ryuko is at her most powerful at the end of the series without Senkestu, she is 9x more power than the SS Naked Sun's durability

>2 x 9 = 18 petatons(Multi-continent Level)

-How powerful is she with Senketsu

>The Goku Uniforms are made up of cloth and percentage of Life Fibers. If you ask me each percentage of life fibers are multipliers

>One Star = 10x

>Two Star = 20x

>Three Star = 30x

>After being truly in sync with Senketsu and the fact that he's 100% Life Fiber would give her a 100x multiplier

>In her base form without going to her strongest form that is Kisaragi, she can unleash a force of 1800 petatons or 2 Exatons(Multi-Continent Level)

>So the question is what is the full power of Kisaragi? The Kisaragi form is the result of Ryuko absorbing the entire student body that includes all of the Students, Club Presidents, Elite 4, and Satsuki's Junketsu. So the question is how many students are there in Honnouji Academy? Since there are no official number of students, since  it's a big school. Comparing the student count to the biggest Japanese schools around which is Inagakuen Public High School who has the student count of 2700

>2 x 2700 x 10 x 20 x 30 x 100 = 3,240,000,000 Exatons or 3.24 Ninatons(Large Planet Level)

>According to Death Battle, the force to bust a hole in the Cocoon Genesis Sphere which is 659 Exatons. She intentionally let Ragyo beat her up to the point of overpower her, since Ragyo's Kamui can handle both the power of Junketsu and Senketsu which means it's a 200x multiplier and since she when through 3 buffs which means at her most powerful she gained a 600x multiplier and Ryuko absorbed her Kamui so that's her buff too.

>659 x 600 = 395,400 Exatons or 395.4 Zettatons(Planet Level)

Final Verdict: Multi-Continent Level without Senkestu, Multi-Continent Level to Large Planet Level with Senketsu

Stats(Speed):

-Slicing Tennis Balls

>According to this: https://vsbattles.fandom.com/wiki/User_blog:Migue79/Ryuko_Matoi_220_Tennis_Ball_Slice_Re-Calc

>Ryuko can attack at speeds of 6856753.311 MPH or Mach 9007 which is Sub Relativistic Speeds

>If I divide the multiplier of 20 since she fought Omiko at the beginning of the series which is 342838 MPH or Mach 450 which is Massively Hypersonic without Senketsu

>342838 x 100 = 34283800 MPH or Mach 45,038 which is Sub Relativistic+

>34283800 x 2700 x 10 x 20 x 30 x 100 = 55,539,756,000,000,000 MPH or 82820990x the speed of light

>55,539,756,000,000,000 x 600 = 33,323,854,000,000,000,000 MPH or 49692594691.3x the speed of light

-Flying to space

>According to Death Battle, flew at speed of Mach 7779.63 or 5969070.083 mph in Kisaragi form

>5969070.083 x 600 = 3581442050 MPH or Mach 4,704,933.3 which is 5.34x faster than light

Final Verdict: 49692594691.3x the speed of light in attack speed, 5.34x faster than light in flight speed

Weaknesses:

-Can only fight for a short time before she passes out from blood loss [Pre-Synchronization and Berserk Only]

-She becomes more vulnerable to damage should her opponent manage to cut Senketsu's Banshi threads [This does not apply to End of Series]

-If any part of her body is cut from both sides simultaneously, she cannot regenerate.

-Short temper, which can adverse effects on Senketsu if Ryuko goes berserk. In addition, she doesn't have full control of herself if she is going berserk.

-As a human/Life fiber being, while able to heal from any fatal injury, Ryuko can be killed if her heart is destroyed

-As she can be headstrong and impulsive

Battle

--------------------------------------------------------------------------------------------------------------

Here we see Danny doing some target practice with his ghost rays on some bottles and one of those shots hit Ryuko's bike.

Ryuko: *turns to Danny*"Watch where you're aiming, you dipshit!"

Danny: "Sorry about that."

Senketsu: "Ryuko, he apologized so-"

Ryuko: "Oh no, I'm not gonna let him get away with that!"

Ryuko then pulls the pin on her Seko Tekko and she changes her outfit to prepare for a battle. She then pulls out the Rending scissors and tries to attack Danny as he jumps out of the way from her attacks.

Danny: "I'm going ghost!"

Danny then transforms into his ghost form and charges at her with some ghost rays attacking her. Ryuko tries to attack Danny but she misses him every time.

Senketsu: "Ryuko, he's anticipating you. You should anticipate him."

Ryuko: "Really? I was gonna let him beat the crap out of me, but your plan is way better!"

Ryuko charges at Danny as he then dodges the attack as she then unleashes a powerful slash at the ghost boy as he is launched into the air.

Ryuko: *changes her outfit*"Senjin Shippu!"

We then see Danny unleash a powerful blast of ice to freeze Ryuko in solid ice.

Ryuko: "Son of a bitch!"

Danny: "Want some more?"

Ryuko: *breaks out of the ice*"First you wrecked my ride and now you freeze my ass! You're dead dumbass!"

We then see Danny and Ryuko fight each other as we see Danny hold back Ryuko's Rending Scissors.

Ryuko: "Nice outfit! Did your mommy make it for you?"

Danny then made himself intangible and phase through the ground.

Ryuko: "What the fuck!? Get back here!"

Ryuko then breaks through the ground and she bashes her way to the Fenton Works Lab and she holds up her blades to ready to fight as Danny was wearing the Ecto-Skeleton.

Danny: "Looking for me?"

Danny then punches Ryuko hard enough that she was sent flying into the sky and then she absorbed the life fibers in the sky and she accessed her Kisaragi form.

Ryuko: "Okay assface, you're dead!"

She made her scissor blades go into a Decapitation Mode to use the Fiber Lost technique. She tried to hit Danny but the attack phased through him as he then flew to space.

Ryuko: "Oh no you don't!"

We see Ryuko bash into Danny as he then opens the head to the Ecto-Skeleton and he unleashes a powerful Ghostly Wail to knock her off as she then slash the Ecto-Skeleton to pieces reducing Danny to his normal form.

Danny: "My dad worked hard on that! Let's see if you can handle more of me!?"

Danny then duplicated himself 3 times and then swarm all over Ryuko as she then bash all of the clones in one spot and put her Randing Scissors to Alumni Mode and aim them at Danny and his clones.

Ryuko: "Sayonara you little shit!"

Ryuko then closed the scissors as the real Danny managed to escape at the last second. We see Danny overshadow Senketsu and we see him take control of Ryuko.

Ryuko: "Senketsu! What are you doing!"

Danny: *makes Ryuko fly down to earth and make her ram into multiple buildings*"Let's see how you like it!"

Danny made Senketsu jump off of her as she was in her undies as we see Danny get out of Senketsu and unleash a very powerful Ghost ray and as their physical bodies turned to ashes and they were ghosts.

Ryuko: "What the fuck!?"

Danny then pulls out the fenton thermos and traps both of them in it.

Ryuko: "I'LL SEE YOU IN HELL YOU BEDSHEET ASSHOLE!!!!"

Danny then traps both of them in the thermos and closes it up.

Danny: "Times up lady."
