The voting bio makes Erector an "evil Constructicon" who had "no choice" but to be an Autobot? Yeah that's the same character who was "Programmed to build and preserve. Reluctant to destroy. Only fights when provoked." Yes Erector only has a brief bio but they are the established characteristics and ignoring those to make up new things just makes the whole thing worse.

Even if you liked the Micromaster that bio is so newly made up it may as well be a brand new character and doesn't deserves any votes over the other nominees.
