## Description

We're always dreaming-up new things at Monster and sometimes we totally break convention. Enter Ultra Fantasy Ruby Red. It may be the best tasting Ultra yet! Not too sweet, not too tart; it's got a fresh citrus taste that'll blow your mind. While it's light and super easy drinking, it's serious on performance. Ultra Fantasy is packed with all the legendary Monster Energy blend you've come to expect. We called on longtime friend, Pinky Taylor for design. OG fans might remember seeing him doing live paintings at Monster events as they rolled through town. We've got his painted surfboards and canvases hanging all over HQ. Now you've got your own Pinky masterpiece too. Unleash the Ultra Beast!

Review: One of my favorite flavors. Nice grapefruit taste to it. All cans came intact with no leaks. Good value for the money if you drink a lot of monster.
Review: Ruby Red is my favorite flavor and I wish I had tried it sooner. It provides a crisp, balanced sweetness with a killer grapefruit flavor. The cans arrived in good shape with no loss in carbonation or leakage.

### ⭐⭐⭐⭐⭐ Review
*by R***E on 24 November 2025*

This is now my third favorite flavor from Monster, right below Ultra Sunrise and Ultra Zero. It's got a mean citrus punch from the grapefruit flavor that satisfies a lot of the time. The Ultra Sunrise is still my favorite because it's a slightly mellower citrus punch that satisfies when I'm not in the mood for extreme citrus which is how I see this Fantasy Ruby Red flavor. This is hands down the strongest citrus punch out of all the Monster flavors.
