Strongest Pet in Pet Simulator 99 — Best Pets Ranked (2026)

The strongest pets in Pet Simulator 99 are Gargantuan pets — and no single Gargantuan out-damages another. Every Gargantuan scales off your own strongest stat pet and shares one ceiling, so “which Gargantuan” is a question about obtainability, not power. As of September 4, 2026 the Gargantuan Anime Agony is the only Gargantuan the Pet Simulator Wiki still flags as obtainable in the Exclusive Raffle, and the Gargantuan Hippomelon is the permanent route — 0.05% from the Gargantuan Machine Hippomelon Egg.

That scaling is what most tier lists get wrong. Gargantuan, Titanic and Huge pets have no fixed stats. The Pet Simulator Wiki puts Titanics at 3x your best pets and places Gargantuans a class above them (five power question marks against a Titanic’s four), with Level 99 adding up to +100% on top. Raise your single best stat pet and your whole endgame lineup rises with it.

How Pet Damage Actually Works

Every Huge, Titanic and Gargantuan pet uses the same formula: your strongest stat pet’s damage × (1 + level bonus + variant bonus). A Huge always beats your best stat pet on its own; a Titanic multiplies that by 3 and is ridable. Small Exclusive pets are locked at 85%, 90% or 95% of your best pet, which is why they can never compete.

Variant bonuses are not the same across classes — the single most common error in Pet Sim 99 tier lists:

Note the quirk in the Small Exclusive column: a Rainbow out-damages a Shiny there, so you cannot assume Shiny is always best. BIG Games has never published Gargantuan variant multipliers at all, which is why the last column is empty rather than guessed. Levelling is class-agnostic and follows a fixed curve — +15.2% at Level 10, +24.8% at 25, +36.9% at 50, +55.7% at 75, +78.5% at 90 and +100% at the Level 99 cap.

S Tier — Gargantuan Pets (Strongest Class)

Gargantuans come only from Exclusive Eggs, Gargantuan Machine Eggs and occasional events. They always carry Exclusive rarity with five power question marks, seat up to four extra riders (who cannot steer), have a Ground Slam ability that deals AoE damage to breakables in radius, and are stamped with a serial and the hatcher’s username — they are the only pets whose variants get their own serials.

This is a shortlist, not the full class. The wiki documents roughly 64 Gargantuans, and since they all share one damage ceiling, ranking them by damage would be meaningless. The pets below are the ones that matter for a player deciding what to chase or buy today, ordered by how you get them.

What You Can Actually Get Right Now

Gargantuan Anime Agony — obtainable. The wiki’s Exclusive Raffle table (revised August 14, 2026) lists it as the only Gargantuan still marked “Obtainable: Yes”. The raffle runs through The Forever Pack in the Exclusive Shop: one pet per round, one winner per round, rounds last 30 minutes, and tickets come from the Forever Pack, weekly pack rewards, buying 35 or 170 Exclusive Eggs, buying 30 Exclusive Card Packs, or an MVP subscription.

Gargantuan Hippomelon — the permanent route. The Garg Machine and Daycare produce the Gargantuan Machine Hippomelon Egg, whose ladder runs Huge Lunar Deer 49.45%, Huge Electric Slime 30%, Huge Dino 15%, Huge Ducky Magician 4%, Huge Midnight Axolotl 1%, Titanic Lucky Cat 0.5% and Gargantuan Hippomelon at 0.05%. The egg costs 800 Robux at 50–74 machine points, 300 Robux at 75–99, and is free at 100. This is the only Gargantuan route that does not depend on an event window.

Gargantuan Tokusatsu Spider — limited. Hatches from the Exclusive Tokusatsu Egg at 0.02%, the rarest pull in that egg (Tokusatsu Sabertooth 48%, Ladybug 35%, Crab 13%, Huge Sabertooth 3%, Huge Crab 0.78%, Titanic Tokusatsu Wolf 0.2%). It was added August 8, 2026. We could not confirm whether that egg is still on sale as of September 4 — the wiki’s egg page has not been revised since August 14.

The Lucky Block Gargantuans — real, but undocumented. Roblox’s own event listing for Lucky Block Breakout (August 22 – September 5, 2026) promises a “Limited Gargantuan Pet”, and the follow-up Lucky Block Blitz (August 29 – September 5) says “The GARGANTUAN is BACK!”. Three Gargantuan asset icons were uploaded to the wiki by an admin at 17:15 UTC on August 22, about an hour after the event opened: Gargantuan Lucky Block Angelus, Gargantuan Lucky Block Shark and Gargantuan Cardboard Dominus Astra. A Golden Lucky Block Angelus and two items called the Lucky Gargantuan Key and Lucky Titanic Key followed on August 29. The pets are real; how you obtain each one has not been documented by BIG Games or the wiki, so we are not going to invent a method. Our Pet Simulator 99 update log tracks this event as it is written up.

Trade-only Gargantuans worth knowing

The Gargantuan Capybara (July 18, 2026) came from the Obsidian Forever Pack. The Gargantuan Rose Wolf (July 25, 2026) was the Coin Boss jackpot after reaching Rebirth 6 in the Pets vs. Coins event, which closed August 8 — our July 2026 update breakdown covers that stretch. The Gargantuan Leprechaun Fox went to players finishing 1st–100th in the St. Patrick’s 2026 Max Level Raid Race, and the Gargantuan Glass Squid was the 0.01% chase pull from the now-retired Exclusive Glass Egg. All four hit exactly as hard as any other Gargantuan — you just have to buy them on the trading market.

The Fiesta Gargantuans — Gargantuan Sombrero Cat and Gargantuan Stealth Dragon, both added August 8, 2026 — are also trade-only now that the Piñata Maze event has ended. Their in-game icons exist on the wiki but no page records how they were awarded, so we no longer state a route for either.

A Tier — Titanic Pets (3x Your Best Pets)

Titanics are the workhorse endgame class: 3x your best pets, ridable, available in far greater numbers than Gargantuans, and shown with four power question marks. The current Lucky Block event added at least nine of them — Titanic Lucky Block Hydra Noob, Lucky Peacock, Lucky Block Tiger, Lucky Surprise Cat, Royal Cloud Cat and Cardboard Floppa on August 22, then Lucky Chest Mimic, Lucky Bearserker and Lucky Surprise Dragon on August 29. As with the Gargantuans, the drop routes are not yet documented.

Verified trade-only classics: Titanic Glass Blobfish (0.1% from the retired Exclusive Glass Egg), Titanic Leprechaun Kitsune (St. Patrick’s Forever Pack, removed), Titanic Tokusatsu Wolf (0.2% from the Tokusatsu Egg), and Titanic Jolly Cat — which has never been hatchable in Pet Sim 99 at all. It exists here only as a transfer from Pet Simulator X, which is why its price stays so high.

B Tier — Huge Pets Worth Chasing

Huges always out-damage your best stat pet and stay relevant through the whole run, which makes them the right target while you are still building. The Lucky Block event is generous with them: Huge Cardboard Shark, Cardboard Blobfish, Royal Cloud Corgi, Lucky Surprise Unicorn, Lucky Stacked Capybara, Lucky Stacked Bunny, Lucky Stacked Elephant and Lucky Surprise Ducky arrived August 22, with Huge Lucky Stacked Agony, Lucky Sticky Slime, Lucky Block Demon, Lucky Surprise Axolotl and Lucky Sticky Hedgehog following on August 29.

From the retired Exclusive Glass Egg, the Huge Glass Dominus (0.39%) and Huge Glass Crocodile (1.5%) remain solid trade pickups, and the Tokusatsu Egg gives Huge Tokusatsu Sabertooth at 3% and Huge Tokusatsu Crab at 0.78%. Huge Horseshoe Capybara and Huge Lucki Wolf both came out of the St. Patrick’s Forever Pack and are trade-only. Watch the naming here: Huge Lucki Dominus is not a St. Patrick’s pack pet at all — the wiki records it as a transfer that could only be obtained from the Lucky Egg in Pet Simulator X. If you are working out which of these to prioritise, our Pet Simulator 99 beginner guide walks through the early progression order, and the best pets top 10 covers the picks in more depth.

C Tier — Small Exclusives and Filler

Small Exclusive pets are capped at 85%, 90% or 95% of your best stat pet, so they cannot compete — they exist for collection value and trading. The Cosmic Axolotl is the textbook example: a Companion I pet permanently locked at 85%, from an Exclusive Cosmic Egg that is long off-sale. Glass Kraken (35% from the Glass Egg) is the same story cheaper. Secret pets, which appear extremely rarely after Rebirth 5 and look like items rather than animals, function identically to a 95% Exclusive.

Keep one equipped only while you are short on Huges; the moment you own a Huge, it comes off the bar. We track whether the game has any working Pet Simulator 99 codes to speed up hatching on a separate page.

Pet Simulator 99 in Numbers

Live from the Roblox API on September 4, 2026 for universe 3317771874 (place 8737899170, by BIG Games Pets), plus our own six-hourly player sampling:

The player count is genuinely bimodal right now: the game held the mid-90,000s through the end of August and has settled into the high-40,000s to mid-70,000s since September 1, which is the normal decay of a two-week event heading into its final days.

How We Ranked These Pets

Tier placement is class-first, because the game’s own maths is: Gargantuan > Titanic (3x) > Huge > Small Exclusive (85–95%). Within a class we rank by obtainability, since damage inside a class is identical.

Pet names, drop rates, class multipliers and level curves come from the Pet Simulator Wiki (class pages last revised July 26, 2026; the Exclusive Egg and Raffle pages August 14, 2026). Event dates and the live roster come from Roblox’s own virtual-events listing for the game and from dated wiki asset uploads. BIG Games has never published a numeric multiplier for Gargantuan pets or their variants, so we do not quote one — any site giving you an exact Gargantuan figure is guessing.

On this pass we corrected the previous version, which was written during the Fiesta event and had gone stale. We removed the claim that Fiesta pets are still obtainable (the Piñata Maze event ended August 22, 2026), dropped a set of Fiesta mechanics figures we could no longer source, replaced an unlabelled live player snapshot with a dated median and range, and fixed Huge Lucki Dominus, which we had described as a St. Patrick’s pack pet when it is a Pet Simulator X transfer.
