You just lost a run you were winning. Your best cat — the one with four stacked mutations and a perfectly tuned DoT build — turned hostile and wiped your team. That’s Dybbuk’s possession mechanic. If it was something else entirely, Mewgenics has 431 enemies across three acts that would like a word with you.
Not all of them deserve equal preparation time. The Lil’ Rats and Flies scattered through Act 1 exist as resource sinks, not run-enders. Dybbuk, Guillotina, and Champion enemies with Evolving buffs belong to a different category entirely — they require specific builds and deliberate tactics, or they dismantle teams that look fully prepared on paper. Mewgenics landed on our best roguelikes of 2026 list precisely because that gap between enemy types is where the real game lives.
This tier list ranks Mewgenics’ major enemies and enemy types from S (run-enders that punish every unprepped mistake) to D (manageable with standard builds), with the counter builds that neutralize each threat. Rankings cover bosses, mini-bosses, and Champion elite variants by actual run-kill risk — not raw HP totals.
Verified against Mewgenics Early Access — April 2026. Values may change with patches.
How This Tier List Works
Each tier reflects a threat’s ability to end a run when encountered without targeted preparation:
- S-Tier: Run-enders. Punish unprepped teams through mechanics that bypass your HP entirely — possession, phase-swapping, infestation.
- A-Tier: High threat. Dangerous without specific counters, survivable with the right build approach.
- B-Tier: Situational. Lethal to specific build types (Thorns-heavy, melee-dominant) but manageable for others.
- C-Tier: Manageable. Threatening on paper but counterable with standard approaches.
- D-Tier: Fodder. Resource sinks only — but see the Champion caveat below.
S-Tier — Run-Enders
Dybbuk (Act 1, Boneyard — Final Boss)
Dybbuk sits at S-tier not because of its 85 HP — it scales to 136 on Impossible difficulty — but because of the two-part mechanic that punishes every standard tactic simultaneously. The Backflip dodge makes direct single-target attacks near-useless: Dybbuk automatically repositions to an empty adjacent tile when targeted, meaning melee-only builds spend their turns hitting air. The Lick ability drains your mana reserve, crippling spell-heavy teams that need Mana for the AoE counters that actually work against it.
Bring Dybbuk to 1 HP and it possesses whichever cat delivers the killing blow. That cat immediately turns hostile. Unless you’ve deliberately set up an expendable unit for the killing shot, you’re fighting your strongest build against your own team as a second phase.
Counter build: Damage-over-time effects — Bleed, Poison, Burn — bypass the dodge mechanic entirely. Before engaging, corner Dybbuk using familiars or tank units to remove its escape tiles; Hunter, Necromancer, and Druid classes have the strongest summoning support for this. When approaching 1 HP, designate your weakest cat for the killing blow. The possession fight ends significantly faster that way.
Guillotina (House Boss — Three Encounters)
Guillotina invades your house three separate times, each escalating. Phase 1 (400 HP) swallows cats whole — direct removal, not damage, so healing does nothing once the swallow triggers. Phase 2 splits into a mobile severed head (250 HP) and a separate body (250 HP) that move independently. Phase 3 reconnects as an infested variant (200 HP head, 400 HP body) and adds a Shriek debuff to its attack chain that strips stat buffs.
Counter build: DoT effects are essential across all three phases for consistent damage without requiring direct contact. In Phase 2, keep the head and body separated — allowing them to reunite triggers a combined attack sequence. In Phase 3, prioritize the head: lower HP, and eliminating it removes Shriek before it degrades your stat stack.
The Creator / The Destroyer (Act 3 — True Final Boss)
Phase 1 (The Creator) is entirely immune to all damage and status effects. Instead, it summons perfect clones of your party and turns them hostile. The clones carry your builds, your stats, and your DoT loadout against you — which means the more optimized your team, the harder Phase 1 becomes. Phase 2 (The Destroyer) introduces a directional shield that blocks attacks from the same angles consecutively, requiring coordinated alternating-side attacks. It’s the longest sustained fight in the game.
Counter build: In Phase 1, focus the highest-damage clone first — it mirrors your strongest cat’s abilities. In Phase 2, coordinate your team to attack from alternating sides during The Destroyer’s Holy Blast windows when the shield drops. Build asymmetrically across your party so that no two cats are identical; mirrored teams hit harder in Phase 1.
A-Tier — High Threat, Specific Counters Required
Spinnerette (Act 1, Caves — Final Boss)
Spinnerette webs units in place, wastes their turn, and infests them with spiderlings. When an infested cat dies, the spiderling erupts from the corpse and permanently destroys the body — no reviving, no recovery. The fight also spawns Spider Cats mid-encounter that amplify pressure.
One rule that most guides bury too deep: attack Spinnerette from behind and she enrages. Enrage accelerates her ability cycle. Most first-time run losses to Spinnerette come from instinctively backstabbing for the positioning bonus — front-facing attacks only, every time.
Counter build: AoE attacks and Freeze or Slow effects buy critical turns. Keep your team spread out so web hits don’t chain. Never attack from behind under any circumstances.
Champion Enemies — Evolving, Mad, and Resonant Elites
Champion enemies appear in hard battle nodes throughout all three acts with doubled HP, an extra turn per round, and +1 damage and movement. The real threat multiplier is their Elite buff. Evolving Champions gain a new random buff every round — after three rounds, that’s three stacked modifiers on an already-doubled HP pool. Mad Champions gain Madness and stat increases on kills, turning a manageable fight into an emergency the moment they get their first takedown.
Resonant Champions specifically punish spell-heavy teams: they gain stat increases and healing each time you cast a spell. Running a Mage-dominant team into a Resonant elite is effectively buffing your opponent every turn. Identify the elite buff before committing to your attack rotation — the approach to the fight changes completely depending on which modifier you’re facing.
Counter build: Burst Evolving and Mad Champions before they cycle buffs — stalling kills you here. For Resonant, switch to physical attack abilities and avoid AoE spell sequences while it’s alive. The same boss fight with a different elite buff is a different encounter entirely.
Throbbing King (Act 1 — Throbbing Domain, Secret Zone)
The Follow Orders mechanic designates specific safe tiles each turn. Standing on the wrong tile when Throbbing King acts deals significant damage — predictable once learned, disastrous when new. Phase 2 adds piercing Bleed vomit blasts on top of the tile mechanic.
Counter build: Ranged damage from safe tiles, control adds early, Bleed resistance (Cleric class) for Phase 2 sustainability. Respect tile markers before any movement decision.
B-Tier — Situational Threats
Fenrir (Act 1, Alley — Mini-Boss)
Melee-dominant teams lose to Fenrir routinely. He takes multiple actions per round, plants bear traps across every melee approach tile, and acts fast enough that melee cats struggle to close range safely. Ranged-heavy builds find this fight straightforward. The B-tier placement reflects how heavily the outcome depends on build composition at the time of encounter.
Crater Maker (Act 2, The Crater)
Crater Maker runs a predictable four-attack cycle on a 3×3 grid — patience with the cycle makes this manageable for most builds. The counter-intuitive danger: Thorns passives accelerate her phase transitions. If your build carries Thorns-based reactive damage, her phases escalate faster than the normal cycle and she becomes an A-tier threat for that specific build. Swap Thorns-bearing cats out before this fight specifically.
Man in the Moon (Act 2) and Lord Bunga (Act 3)
Man in the Moon’s floating hands block direct damage. Bait the hands into striking the boss instead of your team. The Scalding Orb triggers an instant kill if the boss swallows your unit — awareness of the trigger condition prevents the worst outcome; brute force does not.
Lord Bunga adds an instant-kill aura in Phase 2 that covers all tiles adjacent to his throne. Ranged builds circumvent this entirely. Any melee cat that closes to throne range in Phase 2 is removed immediately.
C-Tier — Manageable
C-tier bosses carry threatening mechanics on paper but have hard counters requiring minimal build investment:
- Boris (Act 1, Sewers): 200 HP but no base attack — Boris only tramples. Edge positioning keeps your team out of his path and converts this into a straightforward DPS check against a large HP pool. Without AoE, this drifts toward B-tier.
- Radical Rat (Act 1, Alley): Throws bombs in cross patterns. Auto-dies after four rounds if you survive. Spread your formation and defuse bombs with ranged units.
- Rat King (Act 1, Sewers): Tanky boss that delegates damage through rat swarms. AoE clears swarms before they pile damage onto a single target. Without AoE available, this moves to B-tier for that build type.
- Lucy (Act 1, Alley): Telekinesis repositions your units and disrupts positioning plans. Disruptive but not lethal if your team has range flexibility to continue attacking from new positions.
- Flushmaster (Act 1, Sewers): Pushes units toward hazardous tiles. Predictable pattern — reposition your cats away from hazards before Flushmaster acts each turn.
D-Tier — Fodder
Standard enemies throughout Act 1 — Lil’ Rats (10 HP), Flies (5 HP), Bats (20 HP, Movement 6), Maggots (10 HP), Skeletons (45 HP), Slimes (30 HP) — function as resource drains. They deal modest damage, die to standard attacks, and require no specialized preparation. The same strategic clarity that carries into Slay the Spire 2 boss encounters applies here: identify the true threats immediately and don’t waste ability charges on fodder when a real threat is in the room.
One caveat worth flagging: Champion variants of D-tier enemies jump two tiers immediately. A Champion Bat (doubled HP, extra movement, one extra turn per round) with a Mad elite buff in a hard node has genuine run-kill potential. The tier list covers base-form encounters — always check for Champion status before committing to a battle node approach.
Build Against Your Actual Threats
Different player types face the same enemies differently. If you’re still learning the game, check our Morbid Metal beginner’s guide for a parallel look at how roguelike indie titles reward threat-first build planning — the same principle applies in Mewgenics.
| Player Type | Priority Threat | Build Focus |
|---|---|---|
| New player | Dybbuk, Spinnerette (Act 1 blockers) | One AoE source; at least one DoT on your team; keep one expendable cat for possession |
| Casual | A-tier Champion elites | Scout elite buffs before engaging; burst Evolving and Mad first; avoid Resonant with spell-heavy builds |
| Optimiser | The Creator Phase 1 clones | Build asymmetrically — varied stats and roles across cats reduce clone threat in Phase 1 |
| Completionist | Guillotina (3x) and Throbbing King | Persistent DoT stack plus a ranged fallback; Bleed resistance for house encounters |
Frequently Asked Questions
What is the hardest enemy in Mewgenics?
Dybbuk has the highest run-kill rate among Act 1 encounters for unprepared teams — the dodge plus possession combo eliminates two standard counterplay paths in a single fight. The Creator is technically more complex as the final boss, but players reaching Act 3 typically carry adapted builds that reduce its surprise factor. Dybbuk catches teams off guard earlier in runs where builds are still forming.
Can you counter Dybbuk without DoT abilities?
Yes. Corner tactics work independently of DoT. Use bear traps, the Grapple ability, or summoned familiars to block all of Dybbuk’s adjacent escape tiles before engaging directly. Once cornered with no open tile to backflip into, standard attacks land normally. This approach requires specific positioning resources that not all builds carry mid-run, which is why DoT remains the more reliable primary counter.
Do Champion enemies count as the same threat tier as base enemies?
No — Champion status effectively shifts a base enemy up two tiers. A Champion Dybbuk at higher difficulty settings (136 HP on Impossible with an Elite buff) is more dangerous than the base fight in a different category. This tier list rates base-form encounters. The practical advice: treat any hard battle node as a tier upgrade across the board, not just for the listed bosses.
