Surtr (Colorful Wonderland) is an alternate outfit for the Arknights operator Surtr, featuring a vibrant, Wonderland-themed design with colorful elements and playful aesthetics while retaining her signature massive sword Laevatein. She remains a powerful 6-star Castoc Alchemist operator known for high-damage arts attacks and self-sustain. In this skin, she embodies a whimsical yet fierce persona in a fantastical setting, diverging from her usual somber, fiery giantess archetype.
