The first female Transformer that I ever encountered. No toy was ever made of her, but there was a Japanese model kit that you can see here courtesy of the modeling skills of Tengu of the Transformers' Multiverse, and someone made an excellent kitbash for a Japanese convention. I don't think I or anyone I know liked her when we were young, but I'm pretty sure if there was a toy made, it would probably end up costing more than TM Hot Rod in the aftermarket. The image was done by Dan's Robot Art. Dan makes awesome graphics and sells t-shirts and posters of various Transformer images that he has made.. Especially check out his groupshots. The bio (with a few slight changes) was written again by Neale Davidson who has done an excellent job.
