Every vape range seems to have a mystery blue flavour, and Mr Blue is the Elux ENE Legend take on that beloved puzzle. It never tells you which berry it is, and that is the whole point. What you get in these replacement pods is a mixed blue fruit candy blend, the sort of flavour that reminds people of blue slush, blueberry sweets, and that unmistakable blue raspberry taste you cannot quite trace to any real fruit. If you grew up on blue coloured lollies and fizzy drinks, this one lands with a jolt of pure nostalgia.
Cracking open the flavour
The first inhale is bold and sweet, and it leads with that iconic blue raspberry note. It is candied rather than fruity in a natural sense, with a bright, almost fizzy quality that snaps across the tongue. There is a berry backbone under it, a mix of blueberry and darker berries, but the top layer is unapologetically sweet shop, the flavour of a blue slush drink on a hot day. It arrives with confidence and there is nothing shy about it.
As the vape develops, the deeper berries come through and add some weight. This is where you notice the blueberry doing its work, lending a jammy roundness that stops the blue raspberry from feeling thin or purely synthetic. There can be a subtle tartness threaded through the middle, a gentle sour tug that keeps the sweetness from running away with itself. The result is a candy flavour with a bit of dimension, sweet on top and rounder underneath, which is more than a lot of blue vapes bother to deliver.
The exhale is smooth and sugary, leaving a cool tinged berry sweetness on the palate. Some blue blends carry a faint icy lift on the finish, and Mr Blue has just enough freshness to make the aftertaste feel clean rather than sticky. What lingers is that recognisable blue sweet taste, the flavour that makes you think of childhood tuck shops. It fades slowly and pleasantly, and it is exactly the kind of moreish finish that keeps a mystery flavour in heavy rotation.
Who Mr Blue is made for
This pod is built for the sweet tooth. If you love candy, slush, and dessert style flavours, or if you are the sort of vaper who always gravitates towards the blue option on the menu, Mr Blue will feel like it was made for you. It is also a great pick for anyone who finds natural fruit flavours a bit tame and wants something with more of a fun, indulgent, sweet shop character.
It is worth being honest about who should skip it. If you prefer authentic, true to life fruit or you dislike heavily candied sweetness, Mr Blue may read as too sugary for your taste. Vapers who chase clean, crisp, realistic profiles will likely find it too much of a treat. This is a flavour that leans into being a guilty pleasure rather than a subtle everyday fruit, and it makes no apology for it.
The mood and the moment
Mr Blue is a feel good flavour, so it suits the moments when you want a bit of fun. It is brilliant as an afternoon pick me up, a reward after a long shift, or a companion on a lazy weekend when you are not overthinking things. Because it is sweet and slightly cooling, it works surprisingly well in warm weather, echoing that ice cold slush drink sensation. It is less suited to being your quiet morning vape with a coffee, since its bold sweetness can clash with breakfast; it is far happier as a treat later in the day.
How it compares and smart rotations
Against a straight blueberry flavour, Mr Blue is far sweeter and more candied, trading realism for that nostalgic blue slush hit. Compared with a blue raspberry only liquid, it has more depth, because the darker berries fill in underneath and give it body. If you have tried other mystery blue vapes from big ranges, Mr Blue sits comfortably in that family while leaning towards the sweeter, slushier end, with a hint of coolness rather than a heavy menthol blast.
Rotation is genuinely important with a flavour this sweet, because a big candy profile is the quickest way to tire your palate if you vape nothing else. The best partners come from the opposite direction: a sharp citrus, a crisp menthol, or a tart green fruit will reset your taste buds and make Mr Blue taste vivid again when you return to it. A simple mint or a light cucumber style flavour also works well as a palate cleanser between sessions. What you should avoid is pairing it with another sweet candy or dessert flavour on the same day, because two sugar heavy profiles will quickly blur together and dull the fun that makes Mr Blue enjoyable.
Getting the most from each pod
Candy and slush flavours are at their most vivid when the pod is fresh, so the opening puffs deliver the sharpest blue raspberry hit. Let a new pod settle for a minute or two after fitting it so the wick saturates fully, which keeps those first draws from tasting muted. Slower, steadier pulls tend to bring out more of the berry depth beneath the candy, while very rapid chain vaping can flatten the sweeter top notes and make the flavour feel one dimensional.
Because sweet, dark berry liquids can be a little heavier on the coil, you may notice the flavour gradually soften as a pod ages, which is a normal cue that it is nearing the end of its life. Swapping to a fresh pod brings the bright blue snap straight back. Store spare pods somewhere cool and out of direct sunlight, sealed until you need them, so the flavour stays true and the sweetness does not turn dull. A cool storage spot also helps preserve that light icy edge on the finish.
Value and everyday practicality
As replacement pods for a reusable Legend device, these are a tidy way to keep a favourite flavour topped up without buying a new disposable every time, and each pod carries a very generous amount of vaping. For a bold treat flavour like Mr Blue, that longevity is a double edged gift: it lasts a long time, but its sweetness means many people prefer to enjoy it in a rotation rather than as their sole all day vape. Adult vapers in the UK aged 18 and over should note the 20mg/ml nicotine cap, and matching the strength to your needs will keep each pod satisfying from the first puff to the last.
Flavour FAQ
What flavour actually is Mr Blue?
It is a mixed blue fruit candy blend, built around that classic blue raspberry slush taste with blueberry and darker berries underneath. It deliberately keeps things mysterious rather than naming a single fruit, which is part of its charm. Think blue sweets and slush drinks rather than fresh berries off the bush.
Is Mr Blue an icy flavour?
It has a light, cool tinged finish rather than a full menthol blast. There is just enough freshness to make the sweet berry aftertaste feel clean and refreshing, in keeping with the slush drink inspiration, but if you want a proper icy chill you would want a dedicated ice or menthol pod.
Is it too sweet to vape all day?
For committed sweet tooths it can absolutely be an all day flavour, but many vapers find its candy intensity is best enjoyed in rotation with sharper or cooler flavours. Pairing it with a citrus or menthol between sessions keeps your palate fresh and stops the sweetness from becoming overwhelming.
