Merciless Monsters 7: Fotavyon

The Fotavyon is a huge reptilian creature which lives primarily near swamps and bogs, or occasionally around underground pools. When standing on all four of its spindly, almost spider-like limbs, the creature is about 8ft tall, and 20ft from nose to tail. It is covered in hard scales, with small groupings of feathers on certain areas of its body. The coloring and location of these feathers is unique to each fotavyon, sometimes lining the jaw or forming a crest on the head, or even covering the entirety of the tail. The only feathers which are consistent for each fotavyon are the ones on the the creatures legs, which flay black like vestigial wings. These do not allow the creature to fly, but it does sometimes use them to leap, or to flap threateningly at an intruder while emitting a deafeningly loud, chrip-squawk sound.

Fotayvons have an elongated jaw, with numerous rows of teeth, and eyes mounted on the sides of their head. Their body is lean, and ends in a strange tube-like tail, with a large orifice on the end of it. The creatures four legs are lean and muscular. While at rest, these limbs orient upwards from the creature’s body, and are turned down at the elbow, with long forelegs so they can reach the ground. Each of the four legs ends in a three fingered claw with an oppasble digit, allowing Fotayvons to pick up objects and manipulate them as a human would, though they lack the intelligence to make use of this ability to make tools or other objects. Though they have occasionally been known to improvise crude weapons such as clubs or stones.

Perhaps the most interesting aspect of this species is that all of its members are female. Or, more accurately, the females of the species are the only ones anyone is likely to recognize as a living creature. The males of the species are microscopic organisms which live in a slimy substance which is excreted whenever the creature lays an egg from the orifice on its tail. When the egg hatches, the newly born female eats this slime for sustenance, and in doing so, also consumes the fotayvon males. The microscopic creatures then live as parasites within their mate’s stomach for the rest of her life.

The digestive process of the fotayvon female creates a large amount of noxious, poison gas. An interesting aspect of the fotayvon anatomy is that this gas is expelled not directly through an orifice, but is instead placed within the creature’s unfertilized eggs, which it must constantly produce in order to siphon off this gas. The unfertilized eggs are under immense pressure from this gas, and if an egg is cracked, the gas will tear the egg apart quickly. Once exposed to oxygen, the gas ignites, and expands rapidly. Occasionally, however, one of the fotayvon males will travel to the egg sac of its mate, and enter one of its eggs. The male then dies, releasing a chemical which neutralizes the dangerous gas, as well as fertilizing the egg.

Fotayvons typically bury their eggs, if it is possible, leaving only a small part of it exposed for the potential child to climb out of. Most fotayvon lairs are surrounded by a small field of slime and mostly buried eggs. The fact that 99% of these eggs are explosive prevents most predators from attempting to eat the eggs, and surroundings its lair with what is essentially a minefield is the fotayvon’s best defense against aggressors.


Moving on spider-like legs, a reptilian creature approaches, ruffling the feathers that cover its body menacingly.

SQ Quick Initiative, Egg Hurl, flying leap


Quick Initiative +4 to Initiative Rolls
Egg Hurl Once per day, the Fotavyon expels an egg through its tail orifice. If in combat, it can make a ranged attack to attempt to hurl one of its eggs at an attacker. An egg created during the stress of combat will never be fertilized.
Flying Leap Using its feathered limbs, a fotavyon can make impressive flying leaps, easily covering distances of up to 50ft with a single bound.
Explosive Eggs When a fotavyon’s egg explodes, it deals 5d6 damage to anyone standing within 5ft of it, and 2d6 damage to anyone standing within 10ft of it. This damage is from the flames and pressure of the gas expanding and igniting. After the initial explosion, a cloud of fumes is left in a 15ft radius from the egg’s location. Anyone who ends their turn in these fumes will be paralyzed until they are taken out of the fumes and given a turn to rest, or until the fumes dissipate 10 rounds later. The fotavyon will often attack this paralyzed character first.
‘Mine’ field The slime covering a fotavyon’s egg field is harmless in and of itself. It is slightly slippery, but not enough to cause any penalties.


Environment Wetlands, or dank caves. They enjoy moist, cool environments.
Organization Solitary
Activity Cycle Fotavyons are diurnal, so they function during the day and sleep at night.
Diet Fish, small mammals; Natural Enemies Dragons, occasionally.
Treasure Typical
