When you think Transformers, you probably think giant robots who turn cars and planes and stuff. You might have a favorite Autobot or Decepticon that you think of.
For me, my favorite Transformer character isn't a robot. She doesn't even like them much.
As Circuit Breaker, she attacked both the Autobots and Decepticons without question and was kind of awesome while doing it.
Sadly, since she is a Marvel character, she's kind of in limbo nowadays. Who knows how the rights for her character work now, but if there's any justice, she should star in the next Transformers movie.
For Circuit Breaker, I used the Heroclix Thunder and a lot of silver and skin color paint.
