Vehicle Mode: What Hasbro did with Chromia makes very little sense. Chromia is either a remold of Moonracer and Novastar or a whole new mold using the same basic design, depending how you look at it. Overall, I prefer this vehicle mode, but they had to include to little blue pegs that are extensions of her gun to plug in on the back to fill in the big empty space. Maybe better than the previous two, but not great.
Robot Mode: Chromia looks great in robot mode. I love the paint apps and head sculpt.
Overall: Chromia is a good toy, but I would have much preferred they keep the combiner parts.
Thanks for reading!
