Our brand image is irreverent, but honest. We aim to give consumers a healthier alternative to current options, which are high in sugar and caffeine. While the brand 'Bad Panda' might imply aggressive imagery, we picture it being more light hearted and irreverent. A lot of energy drinks, like Monster, have aggressive tones. We want something that makes the consumer smile when they see it. That said, it's also a somewhat serious product (insofar as it is moderately expensive compared to the competition, and offers real, tangible benefits), so we don't necessarily want a logo that is too "cartoonish", or overly cute.
Ideas we've considered include having a panda on the different labels doing something mischievous, like covered in blueberry juice, or stuck in the honey pot. Or perhaps the logo is just slightly different for each label - maybe he's wearing a blue bandana on his head for blueberry, and a red one over his face for cherry, etc, etc).
