Mountain Dew Robot
Mountain Dew Robots operate in secret on Earth. Although only one individual member is known, the existence of a divergent future timeline in which an entire complex known as Dew City is built implies that they may be as numerous as the Chevy Autobots. At the very least, there's probably a red one. And a blue one. And two black ones. And a diet one...
The origin of the Mountain Dew Robots is unknown. At least one of their number was awakened on Earth by the All Spark's area-effect, but the others are unaccounted for. They might be aliens.
Mountain Dew Robots have not been identified as either Autobot or Decepticon. Dewbot, in fact, sports the Mountain Dew logo on his forehead where a faction symbol would normally go. Given what little is known about them, the Mountain Dew Robots might even represent their own faction. A faction of REFRESHMENT.
