You stood in front of the Dark Matter Machine for forty-five minutes.

Not because the UI was confusing. Because you kept second-guessing yourself. You had finally farmed enough Dark Matter shards — three weeks of Void World routes, skipped events, and zero trading. Your inventory held one Rainbow Huge Doodle Cat, one Rainbow Huge Prism Dragon, and a signed Huge Event Bunny you overpaid for during the Spring drop.

You picked the Prism Dragon. It looked cooler. The damage number was higher than the Doodle Cat. The machine ate your shards, swallowed the pet, and spat out a glowing Dark Matter variant that pulsed with purple energy.

Then you checked your team DPS.

It went up by 8 trillion. Nice, you thought. Until you checked the Trading Plaza later that day and saw that same Prism Dragon — base Rainbow, not even Dark Matter — selling for 180 million gems. You had just converted 180 million gems of trade value into a pet that would take you 90 hours of extra farming to break even on. And your Doodle Cat, which you should have converted first, was still sitting in your inventory doing a third of the Dark Matter Dragon’s damage.

You didn’t make one mistake. You made three: wrong pet, wrong timing, and wrong math. Dark Matter in Pet Simulator 99 isn’t an upgrade button. It’s an economy. And most players treat it like a slot machine.

This guide covers the full pipeline: how fusion feeds the Dark Matter system, which pets to convert and which to protect, the real cost of every conversion, and the decision framework that turns the Dark Matter Machine from a trap into the most powerful progression tool in the game.

Why Most Players Fail at Dark Matter (And Fusion Along the Way)

Dark Matter failure doesn’t look like failure. It looks like a weaker team and an empty wallet three days later. There are four failure patterns that show up again and again.

Failure pattern one: converting tradable value into untradable regret. Players see Dark Matter as pure power and forget that the input pet had market value. A Rainbow Huge pet that sells for 150 million gems is not just a pet. It’s liquidity. It’s your next enchant. It’s your event war chest. Converting it to Dark Matter locks that value into one team slot. If that slot was already filled by a decent pet, your net gain is tiny while your net worth just dropped by eight figures.

Failure pattern two: fusing into oblivion before converting. Some players think the path is: fuse three pets → get one strong pet → Dark Matter that strong pet → unstoppable. The problem is fusion already destroys value. If your fused output is weaker than your combined inputs, adding Dark Matter on top just gilds a bad investment. You end up with one flashy pet and a team that farms slower than when you started.

Failure pattern three: ignoring the opportunity cost of shards. Dark Matter shards don’t grow on trees. Every shard you spend on a mediocre pet is a shard you can’t spend on your best pet. Players farm 500 shards, get impatient, and convert whatever pet is in their inventory at that moment. Two weeks later they hit 500 shards again, look at their best pet, and realize they should have waited. Now they’re farming another 500.

Failure pattern four: chasing multipliers on pets that don’t matter. A 3x Dark Matter multiplier sounds incredible. On a 25 trillion pet, that’s game-changing. On a 2 trillion pet you never equip, it’s trivia. Players convert weak pets because the percentage looks satisfying, then wonder why their farming speed barely moved.

How the Fusion-to-Dark-Matter Pipeline Actually Works

Pet Simulator 99 runs two separate upgrade tracks that players constantly confuse.

Fusion combines multiple pets into one new pet with random output stats. It’s a lottery. Input three pets, get one back. The output damage is typically 50-70% of the combined input damage, with a small chance to hit higher tiers or special variants. Fusion is for inventory management and gambling, not guaranteed progression.

Dark Matter conversion takes one existing pet and converts it into a Dark Matter variant with a fixed multiplier. There is no randomness. The output is predictable. The cost is shards plus the base pet itself.

These systems do not stack cleanly. A fused pet can be converted, but the fusion does not multiply the Dark Matter bonus. The Dark Matter multiplier applies to the base damage of the pet you feed in. If you fused three weak pets into one mediocre pet, then Dark Matter that mediocre pet, you still have one mediocre pet — just with a purple aura.

The correct pipeline looks like this:

  1. Build a stable active team through hatching, trading, and careful fusion of duplicates.
  2. Identify which team pets are permanent fixtures and which are placeholders.
  3. Farm Dark Matter shards without converting anything.
  4. Convert your highest-damage permanent pet first.
  5. Replace the converted pet’s old slot with the Dark Matter version.
  6. Sell or fuse the displaced placeholder pets.

Notice what is missing: random fusing, emotional converting, and shard spending before your team is locked.

Best Pets to Fuse for Dark Matter Preparation

Fusion is not how you make Dark Matter pets. Fusion is how you clean your inventory so you can afford to buy the pets you actually want to convert. Treat it that way.

Pets You Should Fuse (Safe Fuses)

These pets are fusion bait because they have low trade value, high duplication rates, and no place in a Dark Matter pipeline:

  • Duplicate Rainbow pets from permanent eggs. If you have six Rainbow Doodle Cats and your team only uses two, fuse the bottom four. Even a bad fuse result is better than dead inventory.
  • Old event pets with crashed values. Post-event Huges that dropped 70% in the plaza and show no recovery are fusion material, not investments.
  • Non-Huge Legendary and Mythical pets from early worlds. Once you’re in Void World, a Mythical from Area 40 is worthless for both team slots and trading.

Pets You Should Never Fuse (Protect These)

  • Any pet you plan to convert to Dark Matter. Fusion risks destroying the exact pet you need. Keep it in base or Rainbow form.
  • Titanic pets. Never fuse Titanics. The value destruction is catastrophic and irreversible.
  • Event-limited Huge pets with rising demand. If the pet’s plaza price has climbed 20% in the past two weeks, it’s an investment, not fusion fuel.
  • Your top 5 damage dealers. This seems obvious, but players fuse their 3rd-best pet because they want a “better” 3rd-best pet. Don’t. Protect the team.

The Dark Matter Conversion Priority System

Not every pet deserves Dark Matter. Use this priority order instead of converting whatever glows prettiest in your inventory.

Tier 1: Convert These First

  • Huge pets from permanent eggs with high base damage and low trade liquidity.
  • Pets that occupy permanent team slots and will not be replaced for weeks.
  • Pets that already have your best enchant loadouts attached.

Tier 2: Convert These Cautiously

  • Event Huge pets that you plan to keep long-term and whose trade value has stabilized.
  • Pets that are your best damage dealer in a specific role, such as your main chest breaker or gem farmer.

Tier 3: Never Convert These

  • Placeholder pets you plan to replace within a week.
  • Any pet with active trade demand higher than 100 million gems.
  • Titanic pets, unless you are in the absolute endgame with multiple duplicates.
  • Pets you have not equipped for more than three farming sessions.

The Fusion Economy: Full Cost Analysis

Dark Matter and fusion share one currency: opportunity. Every action destroys some value and creates some value. Smart players track both sides.

Here is the real math on a typical Dark Matter conversion path.

StepActionGem Cost / ValueNotes
1Acquire Huge pet (hatch or trade)50M-150M gemsTrade is usually cheaper than hatching
2Upgrade to Rainbow (if not already)0-5M gemsFuse duplicates or buy Rainbow directly
3Farm Dark Matter shards15-25 hoursOpportunity cost: what else could you farm?
4Convert to Dark MatterBase pet + shardsPermanent. No undo.
5Equip and enchant Dark Matter pet10M-30M gemsEnchants do not transfer

Total investment for one Dark Matter Huge: roughly 60-185 million gems plus 15-25 hours of shard farming.

Now compare that to the alternative: buying a better pet on the plaza. For 185 million gems, you can often buy a stronger Huge or even a budget Titanic. Dark Matter is not automatically the best use of your wealth. It is the best use only when your team is already strong, your enchants are maxed, and the only remaining upgrade path is multiplying existing assets.

The Dark Matter Decision Framework

Run this framework before every conversion. It takes thirty seconds and prevents three-week regrets.

Step 1: The Permanence Test Will this pet still be on your team one month from now?

  • Yes → Continue to Step 2.
  • No → Do not convert. Sell or fuse it instead.

Step 2: The Liquidity Test Can you sell this pet for more than 80 million gems right now?

  • Yes → Strongly consider selling instead. Buy a cheaper conversion target with similar damage.
  • No → Continue to Step 3.

Step 3: The Shard Efficiency Test Is this your highest-damage eligible pet?

  • Yes → Continue to Step 4.
  • No → Farm shards for your best eligible pet first. Never convert your second-best when your best is waiting.

Step 4: The Enchant Readiness Test Do you have the enchants and enchant slots ready for the Dark Matter version?

  • Yes → Convert now.
  • No → Farm enchants first. A Dark Matter pet with empty slots is barely better than a Rainbow pet with maxed slots.

Step 5: The Opportunity Cost Test Could you buy a stronger pet on the plaza for less than the combined value of this pet plus your shard farming time?

  • Yes → Buy the stronger pet. Dark Matter can wait.
  • No → Convert. This is the right moment.

Counter-Intuitive Truths About Fusion and Dark Matter

Your worst Huge pet is often your best Dark Matter target. Players want to convert their shiniest, rarest Huge. But rare Huges have trade value. Common Huges from permanent eggs don’t. Converting a 150M gem Huge destroys 150M gems of liquidity. Converting a 20M gem Huge that does 80% of the same damage destroys almost nothing. The DPS gain per gem lost is far better on the “bad” pet.

Fusing before Dark Matter usually makes you weaker, not stronger. Three Rainbow pets fused into one might look like better conversion material. But if those three pets were doing 30 trillion combined and the fused output does 18 trillion, you just lost 12 trillion to gain a 3x multiplier on 18 trillion. The math: 18 trillion × 3 = 54 trillion. But your old team had 30 trillion from those three slots plus whatever filled the other slots. Fusion shrank your team to feed one slot. Dark Matter multiplies that mistake.

Holding shards is a position. Players feel pressure to spend Dark Matter shards as soon as they hit the threshold. But shards don’t decay. They don’t lose value. The optimal play is often to farm 1,000 shards, evaluate the market, and then convert the best available pet two weeks later when prices have shifted. Patience with shards beats impulse converting every time.

Selling a pet and buying a Dark Matter version is sometimes cheaper than converting your own. The plaza market for Dark Matter pets is thin, but it exists. If you own a Rainbow Huge worth 120M gems, and a Dark Matter version of the same pet is listed at 160M, converting costs you the 120M pet plus 20+ hours of shard farming. Buying the Dark Matter version for 160M and selling your Rainbow for 120M nets the same result for a 40M gem difference — often cheaper than the opportunity cost of shard farming. Always check the plaza before converting.

Dark Matter Farming: Shard Routes and Efficiency

If you’re going to commit to Dark Matter, farm shards efficiently. Wandering Void World randomly is not a strategy.

The most reliable shard farm is running dense breakable clusters in Void World or the highest zone you can one-shot. Dark Matter shards drop from breakable objects and chests, not from bosses or minigames. That means your farming setup should prioritize:

  • Magnitude enchant to hit more breakables per swing
  • Speed enchant to reduce travel time between clusters
  • Pets with wide area attacks rather than single-target burst
  • Dense zones over pretty zones — a cluttered room with fifty small breakables beats a cathedral with ten large ones

Avoid shard farming during major events unless the event itself drops shards. Event currency might look appealing, but splitting your attention between event goals and shard farming slows both. Farm shards during the gaps between events, when the plaza is quiet and your gem income is stable.

For team setups optimized for farming speed, check the PS99 Team Compositions Guide.

FAQ

What pets should I convert to Dark Matter first in Pet Simulator 99?

Convert your highest-damage Huge pets that are already part of your active team and have no trade value. Never convert event-limited pets, Titanic pets, or anything with rising plaza demand. The best first conversions are common Huge pets from permanent eggs with high base damage and low resale liquidity.

How much stronger is a Dark Matter pet compared to a Rainbow pet?

Dark Matter pets typically receive a 2.5x to 3x multiplier over their Rainbow variant, depending on the pet tier. For a Huge pet doing 12 trillion damage as Rainbow, the Dark Matter version often lands between 30-36 trillion. This multiplier applies after all other bonuses, making it one of the largest single power spikes in the game.

Should I fuse pets before converting them to Dark Matter?

Usually no. Fusion is a separate system with its own risk and gem cost. Converting a fused pet to Dark Matter does not stack the fusion bonus onto the Dark Matter multiplier in a way that justifies the fusion risk. The exception is if you already have a fused pet with no other use and converting it is cheaper than acquiring a new base pet.

Is Dark Matter conversion worth it for free-to-play players?

Yes, but only after your team is stable. F2P players should prioritize team slots, enchants, and their first Huge before chasing Dark Matter. Once you have 3-4 Huge pets and a reliable gem income of 50M+ per hour, Dark Matter becomes the best long-term DPS investment. Rushing it earlier starves your account of liquidity.

Can I trade Dark Matter pets in Pet Simulator 99?

Yes, Dark Matter pets are tradable, but their market is thinner than normal or Rainbow variants. Many buyers prefer base pets so they can convert them themselves. Price your Dark Matter pets at roughly 1.5-2x the base pet value, but expect longer sell times. If you need fast liquidity, sell the base pet instead.

How do I get Dark Matter material in PS99?

Dark Matter material drops from high-level breakables in endgame zones like Void World and Doodle Overworld, from specific chest types, and from event rewards. The most reliable farm is running Void World breakable routes with a Diamonds enchant loadout. Expect roughly 1-3 Dark Matter shards per hour from optimized farming depending on your pet team and zone.
