In Norse tradition, the deity known for his ability to shape-shift is Loki. As a cunning figure, Loki possesses the unique power to transform into various forms, including animals and even inanimate objects. His shape-shifting often plays a central role in numerous myths and adventures, highlighting his unpredictable nature and complexity. Loki's transformations can lead to mischief, challenges for gods like Thor and Odin, or even moments of profound insight, illustrating the fluidity of identity and the consequences of deviating from societal norms. Loki serves as both a catalyst for change and a reflection of chaos.
