So, I love Arcee's robot mode. I don't care that it can't stand on its own or that it's got a weird spine. The only thing I didn't like about the mold was that it had one long arm and one stubby one, so I switched out the stubby one with Chromia's right arm. Granted, now she can't transform but I haven't ever been able to successfully get her back into bike mode since I first got her. I put the gimp arm on Chromia but seeing as there are so many clogging the shelves near me I might pick up another for parts/a better Chromia mod.
