Note: I uploaded something similar before, this is an updated version of the previous one. I was trying to get permission to put stuff like this on MCU characters profiles but it didn't work out.
Striking Strength: At least Moon level, Likely Planet Level (Mjolnir is said to be one of the most horrific weapon ever made in the universe by Rocket, who claimed that the Hadron Enforcer could blow up a Moon, which was confirmed by guidebooks. Thor's lightning can break the armor of a Leviathan, this would take 5 Exatons of TNT. Party Thor could fight Captain Marvel. Captain Marvel is stated by Kevin Feige to be able to punch away moons, this was calculated at 9 Exatons of TNT. Captain Marvel also pushed aside some magma from the outer core of Xandar. Which would be 2 Zettatons of TNT or Small Planet Level. Thor was able to cause major damage to Jotunheim, which would be 23 Zettaton of TNT. Thor broke a portion of the Rainbow Bridge after 10 strikes, which was tough enough to contain the power to destroy Jotunheim (which is an entire Planet). Mjolnir was able to fight The Destroyer Armor whose power burns with a portion of the Odin Force, which a portion of can shatter planets.) | At least Planet Level, possibly Multi-Solar System after awakening his true power (Thor was able summon a lightning bolt that was able to knock out Hela for a little bit and was later able to fight Hela to the point were the script said that they could win. Hela could casually destroy Mjolnir with one hand, which would take 93 Zettatons of TNT. This is enough to destroy the Planet twice over. Hela also considered the Tesseract not bad compared to her power, The Tesseract being stated to be able to destroy the planet in both The Avengers Movie and Tie-In Comic. Thor could also summon a lightning bolt that could break the Rainbow Bridge in one shot. Which can take the planet shattering force of the Bifrost. Surpassed Odin who transmuted Frigga into stars and created a constellation of stars from a cup. His strength should be comparable to his durability, he took a beating from Thanos even without Stormbreaker) At least Planet level, Likely Multi-Solar System Level with Stormbreaker (Stormbreaker is the most powerful weapon in all of Asgard's history making it more powerful than Mjolnir and Gungnir. Hurt Thanos with Stormbreaker. Thanos is stated to be the most powerful being in the universe and and biggest the villain so far, this would put him above Surtur who destroyed Asgard which is tougher than Earth and holds the entire Bifrost. A small amount of the Bifrost was able to channel enough energy to destroy Jotunheim. Thanos would also be more powerful than Ego the Living Planet, who has a Large Planet level to Small Star Level feat. Thanos was pretty unfazed from snapping the Infinity Gauntlet even with Stormbreaker in his chest, Rocket stated that the snap released a power surge that was unlike anything the universe had ever seen. This would make the power surge Thanos felt more powerful than things like Supernovas, Black Holes and even Gamma Ray Burst. GRB are the equivalent of 100,000 supernovas going off simultaneously and Magnetar SGR-1806-20 emitted a flare that in 0.2 seconds produced more energy than the Sun produced in 300,000 years. Thor at the end of Endgame was more powerful then he ever was according to Anthony Russo. Stormbreaker also clashed with The Necrosword, which Zeus stated could kill all the gods of Omnipotent City. Omnipotent City is home to the most powerful of Gods, this would also put them above Khonshu, who was 1/2 of the power needed to move numerous stars in Moon Knight episode 3. We also see two Celestials in Omnipotent City who we saw make Stars and Galaxies in The Eternals. Gorr later uses the power of The Necrosword to spin a sun at 19 times the speed of light. Gorr later stopped Stormbreaker from being sucked into the Bifrost and overpowered its kinetic energy of 525 Tenatons of TNT.)
Speed: At least Relativistic, Likely FTL (He Reacted to and blocked beams from The Destroyer, which are compared to lasers in context of speed. Thor can react to the Iron Legion’s repulsors, Iron Man's repulsors are confirmed to move at the speed of light. Thor once deflated an Ultron sentries beam, which are stated to be light/lasers twice in the same guidebook. Thor able to keep up with Thanos, who reacted to these Iron Man's repulsers. Party Thor could react to Captain Marvel's Photon Blast. Tony reacted to his own repulsers in a Tie-In Comic. In Thor: The Dark World Mjolnir goes from the sun to Earth in around 15 seconds. Even if we assume Mjonir traveled half the distance Mjolnir would be moving 16 times the speed of light. She can also fly at lowest 365,250 Times the Speed of Light. Thor could blitz past a black hole and ignore its gravitational pull which even light cannot escape. He should be comparable to Ikaris, who flew from Earth to the Sun in 7 seconds making him 45 times the speed of light.
Durability: At least Moon Level, Likely Planet Level (Survived Sokovia's destruction. Party Thor took hits from Captain Marvel. Survive the explosion that was caused by him destroying the rainbow bridge, Survived being scraped against the glass of the Bifrost by Hela while going at MFTL Speeds.) | At least Multi-Planet Level, possibly Multi-Solar System after awakening his true power | At least Multi-Planet Level, Likely Multi-Solar System Level (Took a beating from Thanos)
Lifting Strength: Far superior to Smart Hulk, who threw a boulder with 27 Million Newtons of Force. He moved the Rings of Nidavellir which weigh 40,471,893,000,000,000 kg or 44,612,625,428,421 Tons. Theoretically moved 4 Quadrillion Tons.
Powers and Abilities: Weather Manipulation (Earthquakes, Storms, Rain, Tornados, Thunder and Lightning), Weapon Control (Can control Mjölnir and Stormbreaker trajectory mid-air with his mind), Flight (Via Mjolnir and Stormbreaker) Electricity Manipulation and Limited Telekinesis (Can summon Lightning all around him and from the sky. He can even pick up foes with this lightning as show when he awakened his power in Thor: Ragnarok.) Enchanting/Power Bestowel (Unintentionally enchanted Mjölnir to empower Jane Foster and Granted several children his powers temporarily) Dimensional Travel (Can travel realms with the Bifrost via Stormbreaker) Resistance to Mind Manipulation. He Implied that a mind control that could affect a human would not be able to affect him because he was mighty, and took the longest to be affected by Scarlet Witch's mind control
Weapons: Mjolnir, Stormbreaker, and Zeus's Lightning Bolt.
Notes:
WHAT IF?..... takes a characters personality and powers than puts it in different scenarios. So yes, it does count.
I didn't mention Thor's neutron star feat because it's a bit controversial. Even then, Thor was more so was going to die to the heat rather than the kinetic energy of the star.
As you might already know I love Vs Debating. One of the reasons I love scaling the MCU so much is because while the writers do love to show you just how Mighty these characters are, they want to do it were you also enjoy the story they tell. Think of the MCU like God of War. Kratos has a lot of universal scaling but struggles to open a chest and push stone slabs. This is because the creators also want the characters to be relatable and enjoyable. I have gone through numerous Guide Books, Movie Statements, Scripts, Calculations, and interviews to figure out How Strong The God of Thunder Is. I hope you enjoyed this Blog. Have a Blessed Day!!!!!
