Easy Drinking. Hard Working. Full Throttle, presently a Monster Energy brand has two flavors: Original and True Blue. There were more but these are lost to time. The ones I've found reviews for are:

• Blue Demon
• Fury
• Orange
• Citrus
• Red Berry
• Caramel (coffee)
• Mocha Energy (coffee)

They've also redesigned the original and blue agave flavors ~3 times over its rather long 21-year existence. I love Full Throttle but I doubt it will last for much longer. Its longevity is already surprising enough. I think someone's just forgot about it.

Unsurprisingly the taste is very close to the original Full Throttle with less citrus, more notes of fruit. Like cranberry. It no longer reminds me as strongly of sour gummy worms as the original does; much duller flavor; it is a mild taste but, although the can promises this, it doesn't particularly taste like blue agave.
