Not all of the concept designs for Big Hero 6's superhero costume designs were as bright and colorful as what we saw in the final film. In fact, some of the suggestions from the design team were heavy on the black and earth tones—and one put Honey Lemon in cat ears.

These are some of the designs that Big Hero 6 character designer Shiyoon Kim tossed into the mix. While they don't fit with the final visual tone of the movie, they're still a lot of fun to look at, especially when it comes to the many iterations of Honey Lemon. Kim posted these to his Tumblr, where he also has tons of other Big Hero 6 character art, including some of his particularly frightening alternate designs for Yokai.
