A 4-star Pokémon is a perfect 15/15/15: its Attack, Defense and HP IVs are all 15. For ordinary wild encounters, a 2020 analysis of 600,000 verified spawns reported odds of 1 in 4,096, or 0.0244%. Treat that as a historical baseline—not a guaranteed rate for every encounter type or event.
What does 4-star mean in Pokémon GO?
The game’s appraisal system rates a Pokémon’s Attack, Defense and HP. A 4-star result means all three values are 15, for a total of 45/45 IVs. Players often call a perfect-IV Pokémon a “hundo.” Pokémon GO’s inventory search supports appraisal searches from 0* through 4*; enter 4* in the search bar to find your perfect Pokémon. For an individual appraisal, open the Pokémon in storage, open its menu and tap Appraise. The Pokémon GO Help Center explains the appraisal process.
Appraisal is an assessment, not an upgrade: evolving or powering up does not improve IVs. Niantic notes that purifying a Shadow Pokémon does improve its appraisal. See the official appraisal guidance.
How rare are 4 stars exactly?
For ordinary wild spawns, Pokémon GO Hub reported a 1-in-4,096 chance of a perfect 15/15/15 Pokémon (0.0244%). Its November 16, 2020 analysis drew on 600,000 verified spawns, combining manual records and third-party tracker data, and treated the three IV values as uniformly distributed. That makes the figure a useful reported baseline, but it is secondary research from 2020—not an official, current odds statement from Niantic.

Why the encounter source changes the odds
Some encounter types impose a minimum IV for each stat. A higher floor removes low-value outcomes, making a perfect result more likely under the same uniform-roll assumption. Trainer Hub describes these standard floors, while cautioning that special events can differ:
| Encounter source | Reported minimum per IV | What that means for perfect-IV odds |
|---|---|---|
| Ordinary wild catch | 0 | The 1-in-4,096 figure above is the reported wild-spawn baseline. |
| Weather-boosted wild catch | 4 | Fewer possible values per stat than an ordinary wild catch; the exact odds are not stated in the cited guide. |
| Standard raid reward, egg hatch or research encounter | 10 | Under the cited uniform-roll model, six values (10–15) per stat yield 1 perfect combination among 6 × 6 × 6, or 1 in 216. This is a mathematical derivation, not an official or separately published odds figure. |
| Lucky trade | 12 | Fewer possible values per stat than the 10-floor pool; the exact odds are not stated in the cited guide. |
These floors and the event caveat come from Trainer Hub’s Pokémon GO IV guide. The 1-in-216 calculation assumes independent, uniform rolls among the six values from 10 through 15; do not extend it to every event or encounter without confirming that encounter’s rules. The available guidance does not establish a current event-by-event odds table.

Do perfect IVs make a Pokémon best for battle?
No. Four stars tell you the Pokémon has maximum IVs, not that it is the strongest choice in every battle. Species, moves, level and league rules also matter. In Great and Ultra League, where CP limits apply, a Pokémon with low Attack and higher Defense and HP can sometimes be a better fit than a perfect-IV version. Use appraisal to compare copies of the same species, but consider the Pokémon’s intended role before investing in it. Trainer Hub discusses these factors in its IV guide.
