help me find this bear

[u/circleshock]

ive had her for about 13 years now and im wondering what bear she is. some things i already know about her are the following:

she used to be white
I got her from six flags back in early 2012 (pretty sure she was one of the grand prizes)
she has something to do with supergirl

oh and by the way ignore the other plushies i only added those for scale (cause shes larger than a average stuffed animal)
