Loki and Thor are both gods and have immense godly powers that make them somewhat impervious to harm, though they can be beaten; they can lose eyes (Thor) and they can die (Loki). If the metric is physical strength, then Thor is easily the winner.
Thor and Loki are epically powerful gods from the Norse-inspired realm of Asgard, both powered by humanity's belief in them, but it is often shown that the God of Thunder Thor is much more "powerful" than his sibling Loki.
Loki would win in a fight against Captain America. This is because the God of Mischief is stronger, faster, more durable, and more intelligent than Captain America. It would, however, be a close call in Loki's favor because Cap's willpower wouldn't allow him to give in even when Loki has the upper hand.
In AVENGERS & X-MEN: AXIS (2014) #9, Loki found himself in the unfamiliar role as the hero when he confronted the inverted “evil” Thor on the moon. This version of Loki was so pure of heart that he was able to pick up Mjolnir and transform into a version of Thor.
Other than Thor and Odin, certain other individuals have proven worthy of lifting Mjolnir in the primary continuity: Roger "Red" Norvell (a deliberate ruse by Odin) Beta Ray Bill. Buri (also known as Tiwaz, Thor's great-grandfather)
Loki also finally becomes worthy of Mjolnir, which he discovers when he reaches for it during a battle with the newly belligerent Thor. Loki once again became someone who has lifted Thor's hammer when it began to grow too heavy for Thor himself.
Loki – Thor's archenemy and adoptive brother. The son of Laufey, ruler of the Frost Giants of Jotunheim, one of the "Nine Worlds" of the Asgardian cosmology.
Discovering a talent for magic and manipulation, Loki became the god of lies and mischief and Thor's fiercest enemy. Over the years, he's fought the heroic thunder god in many different ways, sometimes directly, sometimes by creating new super-villains, sometimes by tricking allies into turning against him.
Thor doesn't always save the day in Marvel Comics, and some of his biggest losses include falling to Thanos and Gorr the God Butcher. Thor: Love And Thunder revisits Thor after he has lost everything, including his home in Asgard, his brother Loki, and his sense of place in the universe.
Possessing an innate aptitude for magic and sorcery, Loki occupies his youth by pranking his brother Thor, advancing his powers in the process. The trickster god's mystical powers include shapeshifting, astral projection, molecular rearrangement, illusion casting, telepathy, hypnosis, and teleportation.
Answer and Explanation: Loki killed 80 people. In the 2012 film, The Avengers, in a meeting, Thor warns Bruce Banner to be cautious when talking about Loki because he is Thor's brother. The Black Widow responds, "He killed eighty people in two days." Loki is Thor's adopted brother.
The God of Mischief might not be the strongest supervillain on the planet, but he's certainly able to conjure power that can subdue and stop the Hulk in mere seconds.
Asgardian/Frost Giant Physiology: Being an Asgardian/Frost Giant hybrid, Loki possesses superhuman strength to the point where he can lift 30 tons at max, and possesses superhuman durability to the point where he can withstand powerful energy attacks and powerful impact forces, he is bulletproof, his skin, bones, and ...
He was shown to depower Thor and cast spells such as the worthiness enchantment as well as break Loki's spell to regain his memories. Now Odin did tell Thor he was stronger then him (Odin) which some interpret as Odin meaning Thor is stronger than Odin cause Thor now has his fathers power plus his own.
Thor is Immortal, Not Invincible
In Avengers: Infinity War, Thor revealed that he was over 1500 years old. It's clear that age doesn't affect him the way it does normal mortals, as with most immortals, he is aging at a slower rate. While Thor will eventually die, it will take thousands of years for it to happen.
Thor is repeatedly vanquished by the 5 new Phoenix hosts over the course of 12 issues: Colossus, Namor, Cyclops, Magik, and Emma Frost. Colossus even manages to knock Mjolnir out of Thor's hands at one point, demonstrating the strength of Phoenix and why it should not be trifled with.
Thorr Odinson is a villain from the Avengers and is an evil alternate reality version of Thor Odinson as well as a member of the Tyrant Avengers.
As Heimdall was Thor's best friend, Thor took his death the hardest out of the deaths of the Asgardians, surpassed only by the grief he felt for Loki, who died soon after Heimdall. Thor even vowed to kill Thanos after the latter killed Heimdall, despite having been incapacitated.
Hercules / Zeus
While not cosmic (none of that on this list!), he can survive the vacuum of space and resist cosmic attacks. He ranks above Thor here because he's technically the stronger of the two. In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created.
Like most Asgardians, Thor is vulnerable to particular types of magic. One type of magic of Thor finds himself particularly vulnerable to that magic meant to charm an opponent. This makes Thor vulnerable to foes like Enchantress and her younger sister Lorelei.
For example, Marvel – which publishes the Thor comics – issued a “Thor's Hammer” trading card in 1991 that states Mjolnir is made of Uru and weighs precisely 42.3 pounds. That's lighter than a herd of 300 billion mice, much less a herd of 300 billion elephants. But it raises a different science question.
Loki's Asgardian or Frost Giant heritage sets him a cut above the rest of the rather frail Marvel villains. This ancestry grants him superhuman strength, agility, and speed. He's not as powerful as Thor in this regard, but any human enemy will be no match against him.
