At the time, Hasbro had a difficult time trademarking the name 'Jazz'. The solution was to use Meister, which was the character's Japanese name. 'Argent' means silver or a whitish metal. And yes, Zoom-Zoom is the name of the red variant, from Mazda's marketing campaign.
I can't quite remember why he is silver in the Binaltech fiction... Something to do with the Electrum pool from the G1 cartoon... :rolleyes:
