Hasteyrnos, Conqueror of the sands

I designed this creature for a personal project set in an action-RPG game context, focused on boss fights. To give a frame of reference, think of games like The Witcher 3 or Monster Hunter, where the player faces off against forces of nature within a realistic fantasy setting—meaning a world with internally consistent rules that echo elements of the real world.The Hasteyrnos was designed around several core ideas: a dinosaur-inspired foundation with a behavioral twist that adds a touch of fantasy; a cyclical gameplay structure built on three distinct phases, allowing the player to learn and master the creature's patterns; and the concept of a monster that behaves like a machine—using steam to propulse itself through sand—without necessarily looking like one.To further elaborate on the idea of steam-based propulsion, the internal system of the Hasteyrnos can be compared to that of a locomotive. A massive quantity of water is stored and pressurized within specialized organs, generating steam. Once the pressure reaches its peak, the steam is expelled through a network of pores running along its back and beneath its dorsal fin. This mechanism allows the creature to reach impressive bursts of speed while moving beneath the sand, as if it were swimming through it.

As previously explained, the steam-based propulsion also plays a key role in gameplay. The monster follows a cyclical behavior pattern driven by its internal body heat, which rises rapidly during underground combat phases and gradually decreases when it is forced to surface due to overheating.This cycle can be broken down into three distinct phases. It typically begins with a ground-based fight—slow but brutal. Once pressured and pushed to its limits, the creature quickly burrows into the ground and unleashes its signature weapon: steam. Thanks to this ability, it can propel itself at high speed underground and ambush its opponent by bursting out and diving onto it with relentless force. In this state, the beast becomes an unstoppable force of nature—extremely difficult to counter or evade. As the internal temperature continues to climb, the Hasteyrnos eventually reaches a critical threshold, forcing it to surface once again.At this point, it re-engages in close-quarters combat with a slower, more grounded fighting style reminiscent of a classic theropod. This phase serves as a cooldown period, allowing the creature to regulate its body temperature. However, the Hasteyrnos can still surprise the player by releasing sudden bursts of excess steam at carefully timed intervals, partially compensating for its lack of speed and adding an unpredictable edge to its attacks.

Toxinodon, the Swamp bully

This is a project I completed a few years ago, with the goal of designing a monster that could fit within the Monster Hunter game series. The concept behind this design was to create a small-sized creature that could nonetheless pose a serious threat to more experienced players. The core of the combat strategy revolves around a simple rule: never face the monster head-on.The design highlights two main features: a sharp-toothed maw and a prominent tail that’s meant to draw the player’s attention. This tail serves as an obvious weak spot, both visually and in gameplay terms, as the monster has very limited means of protecting this large, trailing appendage.The tail actually serves as an organ for storing nutrients. Due to its body structure, the creature is poorly adapted for chasing prey and instead relies on ambush tactics. It hides in shallow waterways, lying in wait for its next unsuspecting victim. While this hunting method yields limited success, it has been compensated over time by the development of this storage organ, allowing the beast to survive for several weeks without feeding.
