Backstory: There were two young children named Pietro and Wanda Maximoff who grew up in the Eastern European with their mother and father. They watch family sitcoms until one day a Jericho Missile made from Stark Industries destroyed their home and family and they waited for days and days for that bomb to go off until they realized it didn't. So in order to get revenge on the man known as Tony Stark she and her brother undergo experiments involving the Mind Stone when Hydra got their hands on the staff after the Battle of New York and the first formation of the Avengers. When Ultron was created both Wanda and Pietro see him as an opportunity to destroy the Avengers until Wanda discovered that Ultron wants to bring Peace of Our Time which is the extinction of humanity so then she and her brother fought against Ultron and joined the Avengers which brought the creation of Vision and after the battle of Sokovia she lost her brother Quicksilver and now she is with Vision and now she's an Avenger named the Scarlet Witch.

Feats(Strength and Durability):

-Pulled out Ultron's Core from his Vibranium Body

-Destroyed the Mind Stone

-Equal to the Infinity Stones

-Stronger than any Sorcerer even Dr. Strange

-Killed all members of the Illuminati in a weaker body

>Destroyed Professor X's mental state

-Stated to be powerful enough to kill Thanos no problem

-As a zombie, she fought Hulk to a standstill and probably won

-As a zombie, survived the collapse of a building

-As a zombie, she was durable enough to withstand the explosion that Infinity Ultron made to destroy the large pile of Zombies

-Tossed Vision around

-Tanked hits from Miss America

-Broke out of the Mirror Dimension

Feats(Speed):

-Fast enough to catch Fake Quicksilver off guard

-Stopped and send the bullets back to sender

-Reacted to Speed's speed

-Blocked an explosion from Crossbones

-Kept up and react to Thanos

-Fought both Captain Carter and Captain Marvel

Stats(Strength and Durability):

-Pulling out the core out of Ultron's Vibranium body with minimal effort

>If you look at Ultron's stats, anyone capable of shattering or denting Vibranium makes them Large Country Level and since she pulled out Ultron's core from his vibranium body with minimal effort she could be 2x as strong as Thor and Hulk combined which is 1631 Teratons or 2 Petatons, which is Continent Level

-Scaling to the Infinity Stones

>It is been stated that Scarlet Witch can kill Thanos no problem and he withstood the force of 204 Yottatons. Since Hulk, Thor, Captain Marvel, Iron Man, and Dr. Strange managed to hold their own against Thanos I'll make a multiplier which is 60x. That means during Infinity War and Endgame she is Large Planet Level, but when she unlocked her full power as the Scarlet Witch in Wandavision she gets stronger, which means another 60x and then when she got her hands on the DarkHold it is another 60x.

>204 x 60 =  12,240 yottatons or 12.24 Ninatons x 60 = 734.4 x 60 = 44 Tenatons(Small Star Level)

-Killing 838 Captain Marvel

>In Multiverse of Madness, Wanda was able to kill off all the members of the Illuminati including Monica Rambeau's Captain Marvel. Since Monic has the same powers as Carol Danvers, they would be in the same ball park, which is 51 tenatons since Ultron killed off his variant of Carol Danvers. But Wanda killed Monica in a weaker variant of herself, so at her most powerful she would be able to exert a force of 3060 Tenatons which is Large Star Level

-Zombie Scarlet Witch feats

>Destroying the base of the camp, Building Level

>Fighting and Possibly beating Hulk, which is 4.2 Petatons is Continent Level

>Infinity Ultron blowing up a giant pile of Zombies, it takes 295,258,711.05 joules or .07 tons to vaporize a human

https://youtu.be/xHOfAfjJl6A

>Since there are dozens of zombies and a lot of them are offscreen on 3 sides I'm gonna make a estimate of 500,000,000 of them. That would be 35,000,000 tons or 35 megatons of force which is City Level

-Tanking hits from America Chavez

>According to this: https://vsbattles.fandom.com/wiki/User_blog:AbaddonTheDisappointment/Multiverse_of_Madness_Calcs#America_punches_Wanda

>America was able to punch with the force of 392 tons which is Multi-City Block Level

Final Verdict: 

>As a human: Physically is Multi City Block Level, with Chaos Magic is Large Star Level to Universe+ to Low Multiverse Level

>As a Zombie: Building to City level

Stats(Speed):

-Stopping and sending bullets back to sender

>The average bullet can travel up to 1800 MPH or Mach 2.4

>Assuming Bucky fired 12 bullets at her when she was a zombie

>That means she can react to things going at Mach 28 which is High Hypersonic

-Catching Fake Quicksilver off guard

>I know that Agatha used Ralph Boner who looked like Live Action X-Men movie Quicksilver, but I have a theory on this matter. 

>Perhaps Agatha dream walked into the Live Action X-Men universe to see what Quicksilver looks like and what his powers do. So she find someone who looks like X-Men Movie Quicksilver and replicate his powers to be exact

>And this is consistent considering she can react to Speed's speed

>Which is 120x the speed of light, with the Multipliers, that would mean she can react to things going 289,699,200,000,000 MPH or 432000x the Speed of Light

-Scaling to the Infinity Stones

>According to this: https://vsbattles.fandom.com/wiki/User_blog:KLOL506/MCU:_Worrisome_World_Wipe_(Re-do)

>The Average attack speed of the Infinity Stone is 5,504,807.69231 m/s or 12313904.12 mph

>12313904.12 x 6 x 60 x 60 x 60 = 15,958,820,000,000 MPH or 23798x the Speed of Light

-Reacting to Captain Marvel's speed

>According to this: https://vsbattles.fandom.com/wiki/User_blog:Qawsedf234/Captain_Marvel_saves_Tony_and_Nebula

>Captain Marvel has to be moving 1,461,000x the speed of light and since Wanda is more powerful than all the members of the Illuminati would be a 7x. This means she can fight opponents moving at 979,746,600,000,000 MPH or 10227000x the speed of light

-Keeping up with Winter Soldier's running speed

>Without a doubt it's Subsonic
