Easter eggs in Marvel movies are almost as much fun as the movies themselves. True to form, there is no shortage of hidden things in Thor: Ragnarok taken straight from the Thor comics, and then some. Not only does the God of Thunder's long history get a ton of nods in the movie, but so does the Emerald Avenger. In fact, one of Hulk's greatest storylines is adapted for this film – despite the fact that his name isn't even on it!
These easter eggs in Thor: Ragnarok are sure to keep you intrigued until the next Marvel release. While some are pretty well known, others are so obscure you might have never heard of them. Beware, there are Hulk-size spoilers for Thor: Ragnarok in this list. If you haven't seen it yet, feel free to peruse the easter eggs of another recent MCU installment, Spider-Man: Homecoming, instead.
Loki forces Valkyrie to have a flashback when the two face off in Ragnarok, in which she relives her first battle with Hela when her warrior sisters, the Valkyrior, were all killed. During the sequence, one particular tall, blonde warrior dives in front of Valkyrie to shield her from a killing blow, sacrificing herself. Though it's never confirmed, the implication is that this heroic warrior is the original Valkyrie, Brunnhilde.
When Hulk is not in his armor on Sakaar, he's in relaxed attire with bead necklaces and a lower body wrap. This leisure warrior garb is not only fitting, it is also a direct homage to his outfit in Ultimate Hulk.
During Loki's play towards the beginning of Thor: Ragnarok, the characters mention the time Loki turned Thor into a frog. Quite shockingly, this is not pulled from thin air, but is in fact a reference to a character named Throg, the frog version of Thor.
