Relentless IMMORTUS 20% TROPICAL JUICED ENERGY
Released in 2011, Relentless IMMORTUS is a tropical fruit-flavored energy drink from the brand’s juice-infused series. While the UK version contained 50% juice, the German version was downgraded to 20% juice.

One major downside is that it uses a wing-slide can, which leads to significant deterioration over time...

In 2001, while living in the United States, I encountered energy drinks through the dance scene and was deeply impressed. After returning to Japan, I found that energy drinks were considered novelty beverages, so I established a comprehensive website in 2013 to share the true appeal of energy drinks. As an energy drink enthusiast, I began drinking them seriously again, collecting over 7,000 varieties of energy drinks from various countries. I am also active as a critic and expert, receiving media interviews.

Sweet and Tangy Tropical Fruit Flavor & Juice Deterioration

The 20% juice content still gives it a rich, cloudy appearance, but due to deterioration, it has darkened into a deep amber hue. Originally, it had a bright yellow color, fitting for a tropical fruit drink. Unfortunately, the wing-slide can's low sealing quality has caused significant deterioration.

Upon tasting, you'll notice a blend of sweet and tangy pineapple, apple, and guava flavors, followed by the distinct aged taste of apricot due to juice deterioration. This flavor change is inevitable, a downside of the wing-slide can. If it had been a pull-tab can, the degradation might not have been this severe.

In fact, the older UK version with 50% juice used a pull-tab, and its deterioration was much less noticeable compared to this.

Of course, energy drinks are meant to be consumed within their shelf life, so complaining about a decade of aging might seem unreasonable... However, even under normal storage conditions and within the expiration date, wing-slide cans deteriorate much faster than standard pull-tab cans, which is why I’m not a big fan of them.

Design of Relentless IMMORTUS 20% TROPICAL JUICED ENERGY

You probably have no idea what’s going on in this artwork at first glance.

At the top, there’s a figure throwing their head back, covering their face with their left hand, while their right hand has exposed bones where the flesh has withered away. Below, there’s an angel screaming upwards, partially obscured by the dark print.

The older Relentless designs always had poor printing quality, making it difficult to fully appreciate the mythical artwork.

That being said, here’s a version where the details are much clearer:

Ah, this one is much brighter and easier to see. You can clearly make out the exposed radius and ulna bones in the person's forearm, as well as the angel’s face below. The blooming flower on the right also stands out more.

Now, take a look at multiple versions of the Relentless IMMORTUS 20% with this mythological design:

The color variations are wild! The difference in print quality makes for a fun comparison—some cans are incredibly dark, while others are much more vibrant.
