Arcee is an Autobird in Angry Birds Transformers.
Despite being heavily featured in early advertisements and artwork for the game, Stella-as-Arcee was not actually in the game for a very long time. By the time she was added to the playable roster, the original heavily-Generation-1-Arcee design was changed to be more of a merger of Generation 1 and Prime Arcee, complete with a motorcycle alternate mode.
In celebration of the launch of the Angry Birds Transformers game, a costumed actress portrayed Arcee Bird and interacted with fans young and old at New York Comic Con 2014 (despite not being in the game at the time).
