I'm warming to him, as he has a fairly realistic paintjob for a seeker. Sure Bright green would have been show accurate, but also make him look like Kermit the Frog. Not that I got anything against Kermit but I don't think he'd make a good Decepticon.

Lastly Acid storm helps reinforce the Decepticon side for those of other who couldn't aquire/and or aford the botcon set. As without that set the Decepticon Classics are rather badly outnumbered.
