While little information has been released about Thor: Love & Thunder, the upcoming MCU movie may have a connection to Shang-Chi and the Legend of the Ten Rings. Thor: Love and Thunder News recently revealed new promotional materials for the film, highlighting characters such as Thor, Valkyrie, and Jane Foster. More specifically, Valkyrie’s poster unveiled her new title as “King Valkyrie” and stated that she will have to “take up her sword once more to defend her people”. The notable aspect of this description, and the possible connection to Shang-Chi, is Valkyrie’s sword, a Dragonfang.
In Marvel comics, the Dragonfang is an individual sword, which Doctor Strange gave to Valkyrie. In contrast, Dragonfangs is a particular type of sword in the MCU, wielded by the Valkyries as a group. As the only survivor from the Valkyries’ battle against Hela, Valkyrie took her Dragonfang with her to Sakaar, using it again for the first time in Thor: Ragnarok. As shown in Thor: Ragnarok, Dragonfangs are incredibly powerful weapons, capable of piercing ships and killing enemies with a single blow. This strength comes from the swords’ sapphire steel blades and hilts crafted from dragons’ teeth.
Due to this hilt, Valkyrie’s sword has a connection to Shang-Chi and the Legend of the Ten Rings. Shang-Chi gave audiences their first in-depth look at dragons in the MCU, even explaining how dragons arrived on Earth. In the MCU, dragons are mystical beings from other worlds, who travel to Earth through interdimensional portals. Ta Lo, the ancient village with mystical creatures in Shang-Chi, is only accessible through one of these portals and is home to a dragon called the Great Protector. While Valkyrie’s original Dragonfang most likely did not come from Ta Lo, her need for a new sword may send her searching for the hidden village in Thor: Love and Thunder.
Although the Great Protector is the most prominent dragon in the MCU, she probably was not the source of Valkyrie’s original Dragonfang. Thor: Ragnarok introduced dragons into the MCU for the first time with the Fire Dragon. After Thor’s fight with Surtur in Muspelheim, the Fire Dragon broke free from his chains and tried to kill Thor. However, the Fire Dragon was decapitated when Skurge activated the Bifrost Bridge to transport Thor. Since then, the canon comic miniseries, Eternals: The 500 Year War, has featured another dragon sacrificing itself to help the Eternals defeat a Deviant. This indicates that there may be many dragons spread across different realms in the MCU, and Asgardians would have had easier access to many of them than to the Great Protector to obtain teeth for Dragonfangs.
However, Avengers: Endgame established that the surviving Asgardians now live on Earth in New Asgard with no way to travel to other realms. Since Valkyrie lost her original Dragonfang in Thor: Ragnarok, using it to pin Hela to the Rainbow Bridge, she may need a new sword in Thor: Love & Thunder. Stuck on Earth, the only way Valkyrie could obtain a dragon’s tooth for the hilt would be to travel to Ta Lo. Since the Great Protector already gives the citizens of Ta Lo scales for armor and weapons, she may be willing to give Valkyrie a tooth. Although Valkrie could use a different type of sword, her only way to forge a new Dragonfang would be to seek the Great Protector’s help, connecting Thor: Love & Thunder and Shang-Chi and the Legend of the Ten Rings.
