Rung

The Autobots have this, you know, psy-ops specialist. Does anyone remember his name? As part of his duties, he performs the mental assessments of potential Wreckers-to-be. He's very important. He's got... these huge eyebrows. You gotta know who this is describing, right? Collects and builds model spacecraft? Seriously. What's his name? Oh, right! Rung! Thanks. Some seven million years ago, the bot that had once been "Primus" re-emerged as Rung, though his memories seem to be gone.
