Loki, as one of the Marvel Cinematic Universe's oldest and longest-running villains (turned antihero), has racked up his fair share of enemies over the years, from his own people, to the Avengers, to Kang the Conqueror and his TVA. His tendencies towards narcissism and cruel pranks have served to alienate many, and his villainous actions did so even more.

However, he is not without friends. Thanks to his better nature and his natural charisma, Loki has forged several friendships, both before we see him in the MCU and over the course of several movies and one TV series. While these friendships can be fractious, uneasy, and prone to betrayal, Loki has nonetheless managed to have friends of varying closeness.

10 The Warriors Three Mostly Tolerated Loki's Presence

Before Loki's turn to a villain in Thor, three of his most common companions were Thor's best friends, the Warriors Three. Hogun, Fandral, and Volstagg were not especially close friends of Loki, more begrudgingly accepting him with them due to his closeness with Thor.

Nonetheless, they had numerous adventures with Loki and fought alongside him, including working together during Asgard's Virtue Quest, and a foray into Jotunheim. They even defend Loki to Lady Sif, insisting that he is not malicious, merely a trickster. Nonetheless, there is little love lost.

9 Kid Loki Was A Brief Companion

Kid Loki Variant

When Loki is pruned in by the Time Variance Authority, he wakes up in The Void, where pruned Variants (including several of himself) are sent to be devoured by Alioth. Of the fractured and unstable alliances of Loki Variants, Loki finds companions, of which Kid Loki is one.

Kid Loki leaves Loki and Sylvie when it becomes clear that they mean to take on Alioth, a creature he has spent thousands of years avoiding, being unwilling to risk himself for his companion. However, he gives Loki a magical sword to help him, and as a token of their time together, showing that he doesn't completely disregard him.

8 The Grandmaster Mostly Treated Loki As An Underling, But There Was Some Affection

The Grandmaster Thor Ragnarok

When Thor and Loki find themselves separated following their battle with Hela, Loki falls to the surface of Sakaar weeks before his brother. Through unknown means, and unlike Thor, he avoids slavery and manages to work his way into the inner circle of the Grandmaster, Sakaar's ruler.

Despite Loki's plans to eventually kill the Grandmaster, the latter is fond of him, inviting him to parties, to watch gladiator matches with him, and with a deeper relationship implied. Despite this, the Grandmaster has no problems with forcing Loki to hunt down Thor, with implied threats if he does not.

7 Classic Loki Sacrificed Himself

Another of the Variants in the Void, Classic Loki is an older and wiser version of Loki who has come to feel remorse for what he did, and was attempting to return to Thor to make amends when he was captured and pruned by the TVA.

While Classic Loki spends little more time with Loki than Kid Loki, he ultimately chooses to sacrifice his life to save him, conjuring a vast illusion of Asgard to bait Alioth away from him and Sylvie, ultimately dying when his power falters and Alioth captures him.

6 Heimdall Was Closer With Thor, But Had Some Time For Loki

Throughout much of the MCU, Heimdall and Loki have a fractious relationship. In Thor, Heimdall resists Loki's attempts to smooth-talk him early on, and later helps the Warriors Three disobey his rule. In Thor: Ragnarok, Loki, posing as Odin, has Heimdall banished with orders for his arrest.

Nonetheless, while Heimdall is undoubtedly closer with Thor, with the latter even describing him as his 'best friend' by the time of Avengers: Infinity War, there are hints of some fondness between them by the end of Thor: Ragnarok. Heimdall warmly welcomes Loki home and tells him that he'd seen Loki on his way. Loki snarks, but appears appreciative of the sentiment.

5 Frigga Taught Loki Everything she Knew

Frigga, Odin's wife, was a loving mother to both Thor and Loki, treating them no differently despite Loki's adopted status. She supported them both and nurtured their different skills. However, she took a more active role in Loki's development, spotting his talent for magic and teaching him how to weave spells.

Despite Loki going on to use those teachings for villainy, Frigga always believed in him. Their relationship went beyond a loving mother and son, with Odin wryly commenting that she would have been "proud" of a particularly adept piece of magic Loki cast on him. Despite being his mother, Frigga was one of the friends Loki was closest with.

4 Lady Sif & Loki Used To Be Friends

Lady Sif confronts Loki in Loki series

By the time of Thor, Loki and the Asgardian warrior Lady Sif have a distant and cold relationship. She is far more hostile towards him than the Warriors Three are, being reluctant to allow him to accompany them. In Loki, viewers see the roots of this divide—they had once been close, until Loki played a cruel trick right out of Norse mythology, and cut off a chunk of her hair.

Viewers see how close the two were when Sif confronting Loki over this is the painful memory he is stuck in a loop of in a TVA cell. The physical assaults seem to bother Loki less than Sif's contempt, as she lashes out verbally over and over again until Loki, wounded, is forced to admit that he did it because he wanted the attention, due to being afraid of being alone. The pain Loki displays hints at a very close relationship between the two of them that turned sour.

3 Mobius & Loki Ended Up As Buddy Cops

Mobius M. Mobius begins Loki as a TVA agent who intervenes in Loki's trial as a Variant only because he thinks Loki could be useful in pursuing another Variant, Sylvie Laufeydottir. Much of their early interactions revolve around Mobius cutting Loki down to a size where he can develop as a person and be useful as a partner.

Over the course of the series, however, the two develop grudging respect, and then affection. Mobius teaches Loki to become more altruistic, whilst Loki helps Mobius question the TVA and its darker side. Towards the end of the series, when Loki initially wouldn't even shake his hand, the two embrace.

2 Loki Was The Only Person Sylvie Laufeydottir Could Trust

When Loki initially encounters his female Variant Sylvie Laufeydottir, the two are antagonistic towards each other, with mutually opposing goals. As time passes, however, they enter into a wary alliance while openly admitting that they find it difficult to trust each other.

Over the course of their alliance, however, they drift closer and closer, to the extent that they eventually develop a romantic relationship. A key point in their development is when Sylvie falls asleep around him, despite previously claiming to not do so around people because she couldn't trust them.

1 Thor & Loki Have Always Been The Most Important People In Each Other's Lives

Thor and Loki on Earth in Thor Ragnarok

Even when working at cross-purposes, and despite acting as each other's nemeses for much of the MCU, Thor and Loki have a close and unbreakable bond throughout the MCU. After centuries of friendship in which Loki accompanied Thor on many of his adventures, and the two had jokes and bets between the two, they finally come to conflict.

However, even at their worst, they bicker and snark like brothers, and the closest Loki looks to calling off his invasion of Earth is when Thor appeals to him. In the end, Loki cannot bring himself to watch Thor die, and it is Loki's death that hurts Thor the most when Thanos culls the Asgardian Refugees in Avengers: Infinity War.
