In a flashback scene in the movie Thor, we see Odin transforming Loki's appearance from that of a Frost Giant to that of an Asgardian (more here Why does Loki look like he does in the movies?). Moreover, in the same movie it is shown that Odin's spell is not immutable: Loki's appearance change back to his natural blue skin when a Frost Giant touched him and when Loki uses the Casket of Ancient Winters.

Odin changes Loki's appearance

In Loki episode 1, when Loki tries to use his powers in the TVA, Ravonna tells him

Magic powers? They are no good in the TVA.

implying that magic cannot be used in there. Moreover, later in the episode it is shown that even the Infinity Stones don't work in the TVA and, recalling that the Stones bend reality, time and space, they seem in a certain way "stronger" than Odin's enchantment.

So when Loki enters the TVA shouldn't his appearance revert back to that of a Frost Giant?

The implication appears to be that Odin didn't simply cast an illusion on Loki but actually transformed him. This appears to be on a deeper level than most magic we've seen and it wasn't just an illusion that was cast. See Marvel Studios Visual Dictionary for reference:

Blue Frost Giant skin transformed by Odin

Whenever Loki touches Frost Giants or their relics, he temporarily reverts back to his original form, with blue skin and red eyes.

On top of that this magic lasted past Odin's and Loki's deaths meaning that it wasn't spell that needed upkeep but rather a one time and you're done deal. The implication from the quote you mention from episode 1 is that you can't cast magic in the TVA. Presumably anything done before entering will still stick around.

You'll note that this seem very similar to the runes Agatha and Wanda cast in WandaVision, it might be that the TVA is guarded by runes. I guess we'll find out in the finale.

Agatha: These are runes, Wanda. Only the witch that cast the runes can use her magic.

  • "Only the witch that cast the runes can use her magic." Could this point to a variant-Odin being behind the TVA?

  • Bringing Agatha into it just begs the question "How was she flying before noticing being surrounded by Runes?" Wile E. Coyote rules - a force doesn't exist until you measure it. Commented Jul 13, 2021 at 16:57
  • @lucasbachmann I can work out a hand wavey explanation of the runes weren’t there initially plus maybe the spell let her hover until cancelled so didn’t need upholding plus Wanda could have been levitating her but who knows?

Odin didn’t just change Loki’s appearance—he fundamentally altered Loki’s biology to make him an Asgardian. It wasn’t just an illusion or a surface-level transformation. To put it in perspective, if a limb were severed by magic, it wouldn’t regenerate upon entering the TVA.

I believe it’s a common misconception that Odin simply cast a spell to disguise Loki’s Frost Giant appearance when he found Loki on Jötunheim as a baby. However, evidence across multiple Marvel projects contradicts this notion.

When Loki “dies” in Thor: The Dark World and actually dies in Avengers: Infinity War, his skin remains the same Asgardian hue and doesn’t revert to his original blue Frost Giant form.

The Loki series reinforces this by showing magic doesn’t work in the TVA, yet he and Sylvie, who have undergone similar transformations, maintain their Asgardian appearance. If it was just a magic disguise, you’d expect it to fade as soon as they got into the TVA, but it doesn’t. This indicates Odin’s “spell” was no mere illusion but a change at a deeper, biological level.

We even see in the fifth episode of Loki Season 1 that both Loki and Sylvie start feeling cold, cuddling up to one another at the Void. This implies that they no longer possess the innate Frost Giant trait of cold immunity, further indicating that their transformation into Asgardians was not a mere illusion.

It’s also noteworthy that in the second episode of Loki Season 1, we encounter a variant of Loki who retains the Frost Giant appearance, highlighting that this is a rare exception among the Loki variants.

Frost Giant Loki

Odin’s intervention did not merely cloak Loki’s true nature; it fundamentally altered his physiology, making him biologically an Asgardian—a change so profound that it persists even within the magic-negating confines of the TVA.
