“ Ultrezekira: The Infernal Hellcat of Malbolge”

Ultrezekira — Infernal Apex Predators of Malbolge, Invisible Hellcats Whose Embers Herald Death

Ultrezekira are huge dire hellcats, a far larger and more fearsome breed descended from the infernal hellcats known as Bezekira. These monstrous devils stalk the shattered slopes of Malbolge, the sixth layer of the Nine Hells. Like their lesser kin, they move unseen in ordinary light, their presence betrayed only by drifting sparks, molten eyes, and the distant tremor of massive paws across collapsing infernal cliffs. To devils and mortals alike, Ultrezekira are whispered of as living executioners of Hell—apex predators whose patience and discipline make escape from their hunting grounds nearly impossible.

Among the species, one legendary specimen is said to stand above all others: Bezarakor, the greatest of the Ultrezekira and a terror even among the devils of Malbolge.

Appearance

An Ultrezekira resembles an immense skeletal dire tiger formed of infernal bone and stretched shadow-black hide. Its gaunt frame reveals rib-like plates beneath its skin, giving the creature a corpse-like silhouette even when revealed. Its eyes burn like twin embers in darkness, glowing through its natural invisibility like coals drifting through smoke. Long claws curve like blackened obsidian blades, and each step releases faint sparks as though its bones grind against the volcanic stone of Hell. Even when seen in magical light, heat distortion ripples around its body, making its true shape appear unstable and ghostlike.

Behaviour

Ultrezekira hunt with cold infernal discipline. Unlike many fiendish predators, they are patient and calculating, often stalking prey for hours—or even days—before committing to an attack. The creatures waste little motion, preferring carefully chosen ambushes over open confrontation. They hunt alone and tolerate no rivals within their territory, though they frequently ignore lesser devils unless those devils interfere with their pursuit.

Habitat

These dire hellcats roam the broken ridges and collapsing mountains of Malbolge, where jagged cliffs, volcanic fissures, and unstable slopes create a treacherous landscape. Ultrezekira move through this terrain with uncanny balance, leaping between fractured spires and prowling along lava-scarred ledges where few other creatures can travel safely. Entire valleys of the layer are said to fall silent when one of these predators claims the region as its hunting grounds.

Modus Operandi

Relying on their natural invisibility, Ultrezekira approach prey unseen, often allowing their quarry to wander deep into their territory before striking. The first sign of their presence is frequently the faint glow of ember-like eyes or the subtle tremor of heavy footsteps beneath the ground. When they attack, the hellcats launch forward with explosive speed, attempting to end the hunt with a single devastating pounce. If the prey survives, the Ultrezekira withdraws into shadow and heat haze, circling silently before striking again from another unseen angle.

Motivation

Though driven by predatory instinct, Ultrezekira appear bound to the rigid hierarchy of Hell. Some infernal scholars believe the creatures serve as living enforcers of Malbolge’s brutal order, eliminating beings that stray too far beyond their station. Others claim the dire hellcats hunt only to satisfy an ancient, insatiable hunger—eternal predators shaped by the merciless laws of the Nine Hells.o satisfy an ancient, insatiable hunger—an eternal predator shaped by the merciless laws of the Nine Hells.

Special Traits

Infernal Invisibility

Like all Ultrezekira, Bezarakor is invisible in nonmagical light. Its molten eyes may remain visible, revealing its presence. It becomes fully visible in magical light or when it chooses.

Heat Distortion

The air within 20 feet of Bezarakor shimmers with infernal heat. Ranged attacks against it from beyond this range have disadvantage unless the attacker can see invisible creatures.

Legendary Resistance (3/Day)

If Bezarakor fails a saving throw, it can choose to succeed instead.

Siege Predator

Bezarakor deals double damage to objects and structures.

Regional Effects

The presence of Bezarakor warps the surrounding terrain:

Infernal heat shimmer imposes disadvantage on sight-based Perception checks beyond 60 ft.
Drifting embers reveal its passage even when invisible.
The ground trembles faintly with its movement.

Actions

Multiattack

Bezarakor makes three attacks: one Bite and two Claws.

Bite

Melee Weapon Attack: +15 to hit, reach 10 ft., one target.
Hit: 28 (4d10 + 8) piercing damage plus 18 (4d8) fire damage.

Claw

Melee Weapon Attack: +15 to hit, reach 10 ft., one target.
Hit: 24 (3d10 + 8) slashing damage.

Pounce

If Bezarakor moves at least 20 ft. straight toward a creature and hits it with a Claw attack, the target must succeed on a DC 21 Strength saving throw or be knocked prone. If the target is prone, Bezarakor can make one Bite attack as a bonus action.

Infernal Roar (Recharge 5–6)

Each creature within 120 feet that can hear Bezarakor must succeed on a DC 20 Wisdom saving throw or become frightened for 1 minute. A frightened creature can repeat the saving throw at the end of each of its turns.

Infernal Stalking (Recharge 5–6) — Signature Ability

Bezarakor vanishes into infernal distortion, becoming invisible until the end of its next turn. It can move up to its speed without provoking opportunity attacks.

If it emerges from invisibility and hits with a Claw before the end of its next turn, the attack deals an extra 27 (6d8) fire damage, and the target must succeed on a DC 21 Wisdom saving throw or be frightened until the end of its next turn.

Legendary Actions

Bezarakor can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn.

Claw Attack. Bezarakor makes one Claw attack.

Stalk. Bezarakor moves up to half its speed without provoking opportunity attacks.

Infernal Pounce (Costs 2 Actions). Bezarakor leaps up to 40 feet and makes a Claw attack.

Hellfire Burst (Costs 3 Actions). Each creature within 15 feet must succeed on a DC 21 Dexterity saving throw or take 35 (10d6) fire damage, or half as much on a successful save.

Ecology

Bezarakor is the greatest known Ultrezekira, a dire hellcat species that stalks the broken cliffs of Malbolge in the Nine Hells. A solitary apex predator, it may stalk prey for hours or even days before striking.

Lesser devils instinctively avoid its hunting grounds. The drifting embers, heat-shimmering air, and faint tremors of its massive paws often warn observant creatures of the hellcat’s presence long before the invisible predator finally strikes.

SPECIAL ABILITIES

Invisibility (Su):
Like all Ultrezekira, Bezarakor is invisible in normal light. Its molten eyes may remain faintly visible in darkness. Magical light reveals its full skeletal form.

Heat Distortion (Su):
The air around Bezarakor shimmers with infernal heat, imposing a –2 penalty on Perception checks relying on sight for creatures more than 20 feet away.

Legendary Resistance (Su 3/day):
If Bezarakor fails a saving throw, it can choose to succeed instead.

Infernal Stalking (Su, 5–6/day, Signature Ability):
Bezarakor vanishes into heat distortion, gaining invisibility until the end of its next turn. If it attacks from invisibility with a claw, the attack deals an extra 6d8 fire damage, and the target must succeed on a DC 27 Will save or become frightened for 1 round.

Infernal Roar (Su, 5–6/day):
Creatures within 120 feet that hear the roar must succeed on a DC 27 Will save or become frightened for 1 minute.

Hellfire Burst (Su, 3/day):
Bezarakor unleashes an infernal explosion in a 15-foot radius, dealing 10d6 fire damage (Reflex DC 27 half).

TACTICS

During Combat:
Bezarakor stalks prey with terrifying patience, using Infernal Stalking to vanish and reposition. It combines Pounce and Bite to deliver devastating opening attacks. Tremors, heat distortion, and drifting embers make detecting the hellcat extremely difficult.

Morale:
Bezarakor fights relentlessly and retreats only when faced with overwhelming supernatural force or creatures of significantly greater power.

ECOLOGY

Environment:
Malbolge, sixth layer of the Nine Hells — jagged cliffs, volcanic fissures, and collapsing infernal mountains.

Organization: Solitary

Treasure: Standard devilish hoard; lairs often contain molten gold, infernal gemstones, and cursed artifacts.

Ecological Note:
Even lesser devils avoid Bezarakor’s hunting grounds. Trails of embers, heat ripples, and faint tremors across volcanic stone often mark the passage of the greatest of the Ultrezekira.

LAIR / REGIONAL EFFECTS

Within several miles of Bezarakor’s domain:

• Heat haze imposes –2 Perception checks beyond 60 ft.
• Sudden tremors force Reflex checks (DC 27) to avoid being knocked prone on unstable ground
• Drifting embers occasionally outline the movement of invisible creatures

Ultrezekira

The ultrezekira, sometimes known as the ‘dire hellcat’, roams the savage lands of Malbolge, hunting anything that moves.

Its invisible nature allows it to sneak up on the unwary, and its vicious claws and fangs make quick work of its prey. Unlike normal hellcats, the ultrezekira possesses the ability to see in darkness as true devils do, via its devil’s eye spell like ability.

Fully 25 feet long from head to tail, this powerful beast roams Malbolge with his pride, preying upon weak and foolish devils that would venture out alone.

The beast is capable of tearing apart an elder dragon and has even supposedly destroyed a tarrasque. Occasionally he leaves Hell to hunt on the outer planes, leaving a swath of death in his path.

Combat

Bezarakor is straight forward in combat. He charges the largest foe, pounces, attempts to rake, and continues to tear into that foe until they are no more. Then he moves on to the next. If foes manage to converge on him, he teleports a short distance away and charges again. While direct and vicious, he is still very intelligent, and will adapt his strategy to account for terrain and other variables.

If surprised, he generally does not waste time with his spell-like ability buffs unless obviously outmatched. When outmatched, Bezarakor teleports away and casts such spells in rapid succession before returning to combat.

If stalking dangerous prey, he typically has them cast upon himself just before pouncing.

Improved Grab (Ex): Bezarakor must hit with his bite attack to use this ability. He can then start a grapple as a free action. If he wins, he establishes a hold and can rake.

Pounce (Ex): If Bezarakor charges he can make a full attack.

Invisible in Light (Ex): Bezarakor is invisible in any lighted area lit enough for a human to see. In darkness he shows up as a faint outline up to 30 feet away. (60 feet for low light vision) Magical darkness smothers this glow.

Spell-like abilities: At will-devil’s eye, greater teleport;

3/day – expeditious retreat, razorfangs, sharp-tooth, superior magic fang.

Caster level 24th.

Skills: Bezarakor receives a +4 bonus on Listen and Move Silently checks.
