Review of the Marchosias by Twisted Beast: a demonic dildo with a serious knot

TL;DR

The Marchosias by Twisted Beast is an XXL sextoy with a refined design and a demonic aesthetic, built to offer a strong sense of progression that culminates in a large knot. Tested here in Large size (with a 10.5-inch knot circumference), it blends subtle textures with an intense locking sensation. Its soft silicone gives it flexibility, making the experience more accessible despite its bulk — though thorough preparation and warm-up remain essential.

This model is clearly aimed at experienced users, already familiar with fantasy toys, who are looking to explore deep, textured sensations and enjoy the progressive, trap-like effect of the design. The Vac-U-Lock compatibility adds a nice level of versatility for those wanting to use it with harnesses or accessories.

In short, a striking and demanding toy — but also a rewarding one — for those who already appreciate immersive XXL experiences.

Exploring the Marchosias by Twisted Beast

For this review, the context is a little special: this wasn’t a personal purchase, but the very first sextoy I received as part of a partnership.
Originally, I had contacted Twisted Beast to propose an interview for my series of articles dedicated to indie makers. The interview was eventually postponed by a few months — it’s still coming — but from our first exchanges, I was fully transparent about the progress of Big Good Dildos, its modest beginnings, and its still-limited audience.
That’s why I was very pleasantly surprised when Joey, the brand’s marketing manager, spontaneously offered to let me try one of their flagship models, the Marchosias.
It’s a symbolic milestone for Big Good Dildos: not only does it represent a form of outside recognition, but also a test of mutual trust, where I commit to maintaining my critical and independent view, while showcasing the artisanal approach behind the product.

A long-awaited delivery

After a few email exchanges, Twisted Beast arranged shipping from the UK, which — post-Brexit — always involves a bit of uncertainty with delivery times. Despite a small delay at French customs, the package crossed the Channel smoothly and with no additional fees upon arrival — a much-appreciated detail for this kind of shipment.

A thoughtful and thematic package

Upon opening, the Marchosias was wrapped in a protective plastic film. But the real surprise came from the little extras: a storage pouch, a sticker, and an illustrated card showcasing the lore behind the creature that inspired the design. These small but pleasing touches show that the brand puts care into its world-building and aims to enhance the overall experience beyond the toy itself.

Choosing the right version of the Marchosias

The Marchosias comes in several sizes and two main color schemes. Depending on your experience level and preferences, you can pick a version that suits you — from a more compact shape to a large-format design — all available in a single firmness optimized for sensation.

Available sizes

The Marchosias is available in four main sizes:

• Small — A compact size, ideal for gently discovering the typical sensations of animal-inspired designs.
• Medium — An intermediate level, more intense, that already offers solid volume for those familiar with fantasy toys.
• Large — A hefty format, made for those with prior experience of large dildos.
• XL — The biggest available size, with a knot reaching 13 inches in circumference, for lovers of intense sensations.

This clear breakdown allows everyone to pick a format suited to their level and preferences. A coherent, well-balanced range that caters to both the curious and the experienced.

Available firmness levels

Twisted Beast models come in two main firmness options: soft and medium.
However, you can’t choose the firmness when ordering: most models are offered by default in soft, while certain specific designs are directly made in medium. This approach simplifies the catalog but limits customization options compared to other makers.

That said, the soft firmness already offers a good compromise — smoother insertion while still delivering marked sensations, especially on structured parts like knots. The rarer medium version increases overall firmness and will suit users seeking firmer, more intense feedback.

Signature colors

The Marchosias is available in two main color variants: Demon Blood and Demon Blood (Shadow).
At European retailers like Gaymegastore, the Demon Blood (Shadow) version is the most commonly offered. To access specific color variants or explore more options, you’ll need to go through Twisted Beast’s official website.

Unlike other makers who offer a wide range of customizable colors, Twisted Beast has chosen a more limited palette focused on dark, fantasy-themed aesthetics. A bold visual choice that won’t appeal to everyone, but it strengthens the brand’s identity.

A demonic design and universe

The Marchosias fits into Twisted Beast’s demonic universe, while drawing from the codes of animal-inspired fantasy dildos — with a beastly design and a pronounced knot. Twisted Beast isn’t trying to push size to the extreme here, but rather offers a toy focused on progressive sensations and an immersive, dark visual identity. Every detail — from the shape to the textures and finishes — is designed to enhance the experience.

A beastly design crafted for sensation

The Marchosias has a silhouette that’s both fluid and formidable. Its asymmetrical, tapered head combines one slightly flattened side and another more pointed one — a detail that affects how it feels depending on the toy’s orientation during use.

The progression is well thought out: the shaft widens gradually, with a distinct bulge on the upper side and three sharper ridges along the underside. These elements create a shifting pressure pattern with each movement, without being too aggressive.

Just before the knot, the diameter narrows briefly — increasing intensity before the final push. The knot itself is large, rounded, and plays its role fully: a turning point that transforms penetration into a full sensory lock. On the Large size tested here, it reaches about 10.5 inches in circumference — more than enough to create a pronounced feeling of passage and entrapment.

A solid base and a beastly presence

Beyond the knot, the toy tapers again before ending in a long, sturdy base, adorned on the upper side with a discreetly engraved pentagram. The sculpted testicles add not only weight and balance, but also contribute to the overall visual identity, reinforcing the model’s beastly character.
Even without a suction cup, the wide base allows the Marchosias to stand upright on a flat surface with ease — a practical feature whether for display or play.

Finally, the chosen color — Demon Blood (Shadow) — plays a central role in the toy’s visual impact: a deep red and black gradient that heightens its infernal aura. Twisted Beast doesn’t offer a wide range of color options here, but instead leans into emblematic, evocative tones that perfectly match the dark fantasy creature universe that inspires the brand.

A creature escaped from hell

The Marchosias isn’t just another animal-style dildo — it’s rooted in a whole dark and infernal mythos.
In esoteric tradition, Marchosias is a great marquis of hell, tasked with relentlessly hunting down those who try to flee their eternal punishment. Twisted Beast draws directly from this figure to design their demon dog dildo: an alpha predator, a demonic wolf ready to lock in its prey once the knot is breached.

As the brand describes on their site, “The demon wolf is here to knot your hole” — everything is crafted to make the toy feel like a real creature, with its own codes, aesthetic, and aura. From the engraved pentagram to the illustrated lore cards included in the package, every detail contributes to an experience that goes beyond the object itself — awakening both the imagination and physical sensations.

An immersive experience between progression and challenge

The Large Marchosias isn’t just a hefty dildo — it’s a toy designed to deliver a gradual, escalating intensity, where every detail matters. It doesn’t try to overwhelm with sheer size, but rather traps and locks you in through an intelligently layered arrangement of textures, shapes, and sensations.

A gradual but distinct entry

The tapered head of the Marchosias makes initial insertion relatively easy for a toy of this category. But very quickly, the textures begin to make themselves known: the first bump marks a clear milestone, and every centimeter adds more pressure. It’s not a smooth glide — you feel every detail of the design, and that’s precisely what makes this model so engaging.

The sensations evolve with movement: at first, the toy feels subtle, but the deeper you go, the more it reveals its true nature. Each thrust accentuates the texture differences, forcing you to adjust your stance, pace, and breathing. It’s this steady buildup — more than the size itself — that defines the experience.

The knot: center of the challenge

The Marchosias knot, with its 10.5-inch circumference (in the Large size), is undeniably the design’s highlight. Contrary to what you might expect, it’s not just a final obstacle to conquer — the entire toy builds up to it, gradually widening and training the body to stretch.

Passing the knot takes patience: it creates real resistance, often requiring a pause to let the body adjust. But the real challenge often begins after the knot is in. The pressure becomes far more intense than in previous stages, and the body — not yet used to that level of tension — may instinctively try to expel it. You have to take time, breathe, relax, and work to keep it in place.

This moment of lock-in — more than the act of passing the knot — becomes the heart of the experience. And that’s what makes using the Marchosias so satisfying: managing to take the knot and hold it in place brings a feeling of control and achievement that’s deeply rewarding. A balance between progression, tension, anchoring… and fulfillment.

Flexibility that shapes the experience

The Marchosias comes in soft silicone, and that choice plays a key role. Without this softness, the toy would likely be too rigid to remain comfortable — especially during long or dynamic sessions. During solo play, the softness can pose a slight challenge, as the toy tends to bend or slip out during vigorous movements. However, I feel that in pegging scenarios or when mounted on a machine, its flexibility could become a real asset, allowing for faster rhythms and deeper sensations — though I wasn’t able to test that directly.

Caring for your Marchosias

An XXL dildo like the Marchosias requires a bit of care to maintain its quality and lifespan. Twisted Beast includes a storage pouch with each toy, which already helps with storage — but a few good practices remain essential.

Cleaning: gentle but thorough

After each use, the Marchosias should be cleaned with warm water and a mild soap or dedicated toy cleaner. Harsh soaps, alcohol-based, or abrasive products should be avoided as they can damage the silicone’s surface.
Once washed, just let it air-dry on a clean surface or use a soft cloth.

Storage: protect the material

Twisted Beast recommends keeping the toy away from other PVC or vinyl toys, as these materials may release chemicals that react poorly with silicone.
It’s also best to avoid storing it under heavy objects that could deform it over time. The provided pouch already helps reduce dust and friction, but for maximum protection, it’s ideal to store it in a clean space, away from sharp objects or pressure.

Usage tips: preparation and lubrication

The Marchosias — especially in Large or XL — is an XXL toy that deserves a well-prepared approach. To ensure a pleasant, discomfort-free experience, attention should be given to preparation, lubricant choice, and potential accessories.

Preparing your body before insertion

Even though the Marchosias’ tapered design eases entry, it’s still an XXL toy that requires real prep.
Good warm-up with smaller toys or muscle-friendly stimulators can greatly help relax the area and allow for a gradual introduction.
Relaxation exercises — such as controlled breathing or voluntary contractions — also help reduce muscle tension and make knot penetration easier and safer.

Choosing the right lubricant

Twisted Beast explicitly recommends water-based lubricants. Silicone-based lubes are to be avoided, as they could damage the toy’s surface.
For larger toys like the Marchosias, thinner lubes such as Xlube (recommended by the brand) can enhance the experience — but any quality water-based lube will do the job.
Don’t hesitate to reapply generously during the session: better too much than too little, especially to fully enjoy the progressive design and textured details.

A detail worth noting: during several sessions, I noticed that even with Xlube, the lube seemed to dry out faster than usual. Is it due to Twisted Beast’s specific silicone formulation, or simply to the toy’s dynamic use (ridges, friction, textures)? That remains to be confirmed over further use, but it’s something to keep in mind — especially for those planning long sessions.

Vac-U-Hole compatibility for harnesses and accessories

The Marchosias comes pre-drilled with a Vac-U-Hole system and includes a matching plastic plug.
This plug allows the dildo to be attached to any Vac-U-Lock-compatible harness, offering great stability for more dynamic partnered sessions. Some compatible accessories (like handles or specific extensions) can also be used with it.

The Marchosias in summary: a bold and unique piece

The Marchosias by Twisted Beast is not just another XXL sextoy — it’s a toy designed to deliver progressive, powerful, and immersive sensations. Its design combines sculpted forms, gradual widening, and a final knot that creates a true locking effect.

In use, it offers a solid balance between flexibility and presence, with soft silicone that makes the experience more approachable while still posing a real challenge. Every stage — insertion, progression, passing the knot — brings its own sensations, turning each session into a fully immersive sensory journey.

This toy is clearly made for seasoned players, already familiar with fantasy toys and ready for a challenge. Beginners would do better to start with more modest models before attempting this one. But for those who enjoy stretching, locking, and the demonic aesthetic it represents, the Marchosias is a truly striking piece — both visually and in use.

Where to buy the Marchosias?

To purchase the Marchosias, you have two main options:

• On Twisted Beast’s official website: there you’ll find the best base prices and full access to the catalog, colors, and special editions. However, when ordering from Europe, be prepared for international shipping fees and possibly import taxes (depending on your country and customs declaration), which can increase the final cost.
• Through Gaymegastore, the official European retailer, which avoids customs fees and ensures simpler and faster delivery. However, the listed prices are often higher than on the official site, reducing the overall price advantage.

• Twisted Beast (UK)
• gaymegastore.eu (CZ)

Before buying, I recommend comparing both options, factoring in actual costs (shipping, potential taxes) and availability — especially if you’re after a specific color or size. In any case, the Marchosias remains a standout piece for lovers of XXL sensations, combining beastly design, bold textures, and a powerful locking effect.
