Was definitely bummed to see the plans for the Arcee toys during the ROTF line fall apart. I actually really liked Deluxe Class Arcee, but sad to see the combination gimmick get ditched mid-line. I had an idea for Arcee in DOTM that was sort of a hybrid between the unused Movie 1 design and the ROTF design. She would have been a standard humanoid design with a half of one of the wheels on each of her knees, and could transform her legs into the ROTF-style unicycle for added speed. Sadly Michael Bay did not care much for the character! At least it got made up for in Transformers Prime.
