Marzi-Mei

From Homestar Runner Wiki

20X6 Marzipan is the 20X6 version of Marzipan. She only appears on Main Page 17 as the mouse-over action on the "Characters" button, where she says "Yatta!" and does the victory sign. The animation she does is identical to Chun-Li's winning pose in Street Fighter II, as is the "Yatta!". ("Yatta!" is a Japanese interjection for excitement, usually translated into "Hooray!" or "I did it!"). Unlike present-day Marzipan, 20X6 Marzipan has visible arms and legs.

Her outfit, hairstyle and general appearance seem to be based on the anime character Sailor Moon.
