Ultimates are Pet Simulator 99's charge-and-release power moves: equip one, let your pets' damage and your taps fill the meter, then fire it for a burst that no ordinary farming matches. They unlock at Rebirth 4, level up through use, and range from workhorse damage surges to exclusive-tier showpieces like the UFO strike.

How ultimates work
One ultimate equips at a time. It charges from two inputs, pet damage and your own taps on breakables, and using it grants XP that levels the ultimate into higher tiers with stronger effects. Rebirth 7 permanently speeds charging by 30 percent and boosts XP gain by 20 percent, which quietly makes it one of the best rebirth perks for ultimate users.
Choosing an ultimate
- For pure farming, damage surges (Pet Surge, TNT Surge, Lightning Storm) convert charge directly into cleared areas.
- Loot-oriented picks like Chest Spell and Hidden Treasure trade damage for drops, better when your pets already one-shot everything.
- The exclusive tier is mostly flex with strong numbers: if you own Black Hole or UFO, they carry both jobs.
Swap ultimates to match the task rather than leveling one blindly: XP invested stays with each ultimate.
FAQ
How do you unlock ultimates in Pet Simulator 99?
Reach Rebirth 4. That rebirth adds the Ultimates button, and from there you can equip one ultimate at a time and start charging it through pet damage and taps.
How do ultimates level up?
Using them. Each activation grants XP toward higher tiers that strengthen the effect, and Rebirth 7 permanently adds 30 percent charge speed and 20 percent XP gain.
Which ultimate is best for farming?
The damage surges. Pet Surge is the safe default, while TNT Surge and Lightning Storm clear dense breakable areas faster. Loot ultimates like Chest Spell pull ahead once your pets already break everything instantly.
