NB: This toy is available in a hand poured technique called fusion. As such, each dildo in this colour is individual, and the colouring of each sex toy using this method are aesthetically different and bespoke.

The Leviathan is a creature of legend brought into sculpted form — a design that blends fascination and fear in equal measure. Its silhouette is long, commanding and unmistakably substantial, built to evoke the presence of something ancient and powerful rising from the depths.

Running the full length of its body is a winding, serpentine twist, lined with well‑defined suckers that spiral in a deliberate, almost hypnotic pattern. This detailing gives the Leviathan a living, creature‑like energy, as though each ridge and sucker belongs to something that once moved through dark waters with purpose.

The overall effect is a slow, immersive journey guided by the creature’s own contours — a design that dominates through presence alone while offering a richly textured, fantasy‑driven experience.

For those who love the thrill of mythical beasts and the artistry of creature sculpting, The Leviathan stands as one of the most dramatic pieces in the collection.

Stability and Texture

Stability
Leviathan features a long, slender profile with a steadily widening lower section.
Due to its extended length and forward‑leaning weight, the toy is not designed to stand unaided and performs best when supported or mounted using compatible systems.

Texture
This toy is a masterpiece of design with gentle skin like texture under a spiral of aquatic suckers ending near the tip which is phallically shaped.
The constant spiral offers prolonged stimulations throughout.

What You Need to Know

All Toys are designed & manufactured by John Thomas Toys®.

This toy is compatible with Vacuum dildo systems including the popular *Vac-U-Lock™ system.

Each of our dildos are individually hand crafted using the finest quality medical grade platinum silicone. Platinum silicone is a very expensive material to source costing more than four times the price of TPE or PVC. Platinum silicone is simply the best material to use in the production of dildos as it is body safe, non-porous, stain resistant and is incredibly durable.

Fusion colours are all unique pours and may differ from that pictured. The colour combinations are the same - but the appearance will always be unique. For example, if you order the GLAMOUR colour - the mix will always be pink, black and gold - but the appearance will not be identical to that pictured. When ordering MULTICOLOUR - this may be a fusion of ANY colour and we will not match the ones picture. This option is for those looking for a surprise.

We use copper moulds to produce ultra-high quality, detailed dildos - unlike many of our competitors who use cheap silicone mouldings. Whilst copper moulds are expensive to create, they create consistently high quality toys every time with perfect detailing and soft texture.

You may clean either by hand or in the dishwasher, and being silicone, you may heat up or cool down the toy for added sensation.

*NB: This adult toy is not a Vac-U-Lock™ product which is owned & licensed by Doc Johnson®.

NB: John Thomas® dildos are generally very large and heavy. Make sure you read the specifications tab carefully before ordering.

I’ve been looking for a tentacle dildo that for both depth and breadth stimulation and stretch. Seeing the Leviathan in large seemed a good combination of penetration and stimulation given it’s dimensions and textures. Boy, was I right!!
The dildo fitted my anatomy perfectly? Providing amazing sensations and challenges to come. A perfect combination. I’ve used the Leviathan a few times and had fun and an anal orgasm, to my pleasure!
The dildo is very well made, very safe to use and relatively easy to clean once you’ve wiped off the residue lubricant.
The surface gives a careful balance of stimulus and slide texture. I use the dildo by hands and explore different rotations to produce the most pleasurable experience.
