A free spirit who loves pushing boundaries and being creative. She has a strong, independent streak that makes her question when things are wrong. Since she believes Emmet is the “Special” from The Prophecy who’s destined to save Bricksburg, sparks have been flying between them, in spite of herself… and her current boyfriend.
The streetwise and free-spirited Master Builder called Wyldstyle knows the best way to escape from Bad Cop and his robot goons. Blasting through a secret portal, she and Emmet travel to the Wild West, a rootin’, tootin’ realm of cattle-rustling, train-robbing, and high-noon showdowns.
Donning old-timey disguises to blend in with the local cowboys and outlaws, they start their quest to find the wizard Vitruvius and save the LEGO world. But although Wyldstyle knows exactly what she’s doing, poor Emmet may be completely out of his league!
She is as "tough as nails" and is Emmet's love interest. As an independent figure, she doesn't let others give her orders easily; as a Master Builder, her creativity rivals even her no-business attitude. Despite this, she has a caring heart and puts a great deal of faith in those she considers friends.
Since meeting Emmet, she believes him to be the "Special", the figure destined to save the LEGO universe. Of course, he doesn't believe himself to be special at all, so it's up to her to convince him otherwise--whether he like it or not.
