What is the perfect PvP IV?

There is no universal perfect spread. The best IVs depend on the Pokémon and league.

Are 100% IV Pokémon good in Great League?

They can be, but many Pokémon fit more total stats under 1,500 CP with lower Attack.

What IVs are best for Ultra League?

Many Pokémon benefit from lower Attack and higher Defense and HP, but Pokémon that struggle to reach 2,500 CP may prefer higher IVs.

What IVs are best for Master League?

Generally, the higher the better. 15/15/15 is normally the ideal.

Should I replace a Rank #50 Pokémon with Rank #1?

Not automatically. Check how much the stats actually change and whether those differences affect relevant matchups.

What Are the Best IVs for PvP?

There is no single best IV spread for every Pokémon in Pokémon GO PvP.

You will often hear that you want something close to 0 Attack / 15 Defense / 15 HP. That is a useful rule of thumb for some Great League and Ultra League Pokémon. It is not a rule to follow blindly.

The best IVs depend on the Pokémon, the league, the CP limit and what you actually want that Pokémon to do.

The Short Answer

Great League1,500 CP: Lower Attack, higher Defense and HP is often good.
Ultra League2,500 CP: Often similar — but some Pokémon need higher IVs to reach the cap.
Master LeagueNo cap: High IVs preferred. 15/15/15 is the obvious ideal.

That gets you most of the way there. The details are where it gets interesting.

Best IVs for Great League

Great League caps at 1,500 CP. Attack raises CP more than Defense and HP, so a lower Attack IV can let some Pokémon power up to a higher level before crossing the limit. More levels, more bulk.

That's why good Great League spreads often look something like:

0 / 15 / 151 / 14 / 152 / 15 / 13

These show the general shape, not universal targets. For one Pokémon, 0/15/15 may be excellent. For another, Rank #1 is something else entirely. Check the individual Pokémon before you spend Stardust and Candy.

Best IVs for Ultra League

Ultra League caps at 2,500 CP. Same mechanics, so lower Attack with higher Defense and HP is often useful.

But there are more exceptions. Some Pokémon need very high levels just to approach 2,500 CP. If a Pokémon struggles to reach the cap, giving up Attack buys you nothing. Higher IVs can actually be better there.

Low Attack is common in PvP. It is not automatically better.

Best IVs for Master League

Simpler. Standard Master League has no CP cap, so you aren't squeezing extra levels under 1,500 or 2,500. You want the strongest version you can build — which makes 15/15/15 the normal ideal.

A slightly imperfect Pokémon can still do fine. There's just no CP advantage to lowering Attack on purpose.

Is 0/15/15 the Best PvP IV?

Sometimes. Sometimes it's nowhere near Rank #1.

The idea caught on because it neatly shows the typical Great/Ultra League pattern: low Attack, lots of Defense and HP. But every Pokémon has different base stats, and those change how its IVs interact with the CP formula and the cap. Two Pokémon can have completely different optimal spreads in the same league.

Use 0/15/15 as a clue. Not as an answer.

Is Rank #1 the Best IV Spread?

Rank #1 normally means the highest stat product under the calculator’s settings. That makes it a great benchmark. It doesn’t mean every lower spread is worse in every battle.

Version A

Lower Attack, more bulk, Rank #1 stat product

May

survive longer
absorb more Fast Move damage
reach another Charged Move

Version B

Slightly higher Attack, slightly less bulk

May

win CMP
reach a damage breakpoint
behave differently in a mirror

Neither one wins everywhere. It depends on what you're facing.

Should You Choose Bulk or Attack?

For most players, high stat product is a very good starting point. Bulk helps in a lot of matchups — more Defense and HP can keep a Pokémon alive longer and sometimes get one more Charged Move out.

Attack-weighted builds are more situational. They matter for:

Charged Move Priority
damage breakpoints
mirror matches
specific meta matchups

The better choice depends on why you are building the Pokémon.

How Good Is Good Enough?

Say you already have a Rank #24 — or a Rank #87 — of a strong Great League Pokémon. Do you really need Rank #1?

The rank gap often looks much bigger than the actual difference in battle. Before pouring Stardust, Candy or weeks of trading into a tiny upgrade, ask: does the better spread change anything important?

For most beginners and intermediate players, a very good Pokémon now beats waiting forever for theoretical perfection.

What Matters More Than Perfect PvP IVs?

Plenty. Whether the Pokémon is actually strong in the meta, its moves, and how your team fits together. Then the battle skills: matchup knowledge, shield management, switching and energy management — including counting Fast Moves.

So, What Should You Keep?

For Great League and Ultra League, low Attack with high Defense and HP is a useful starting point. For Master League, look for high overall IVs.

But don’t transfer a Pokémon just because its IVs don’t look “PvP-shaped”. And don’t assume 0/15/15 is automatically good. The exact answer is different for every Pokémon.
