Pokeball Progression

Pokeball progression data is being added for Black 2 & White 2

Pokeball progression is currently verified for Red & Blue and FireRed & LeafGreen. Other games will be added as we verify mart inventories and pickup locations against authoritative sources.

How to Catch Pokemon

In Black 2 & White 2, every wild Pokemon has a hidden number called its catch rate, somewhere between 3 and 255. The higher that number, the more likely the Pokeball is to stay closed when you throw it. Common Pokemon like Patrat sit at 255. The Tao trio Kyurem hits the floor at 3, which is why high-stakes legendary catches still take so many tries here.

Three things change your odds the most: how low the wild Pokemon's HP is, what status condition you put it in, and which Pokeball you throw. Drop HP first, apply Sleep or Freeze for a 2.5x bonus (Paralysis, Burn, or Poison gives a smaller 1.5x boost if Sleep is not an option), then throw the situational ball. Generation V is where the Sleep multiplier jumped from 2x to 2.5x, and Quick Ball ramped from 4x to 5x at the same time. The same opener pays more here than it did in Gen IV.

How to Increase Your Catch Chance

Multipliers compound. The standard sequence is weaken HP, apply Sleep, throw the situational ball. With the Gen V status math, the cumulative gain over a no-prep Ultra Ball throw is bigger than any earlier generation.

1Weaken HP with False Swipe. Knock the wild Pokemon to 1 HP without knocking it out. False Swipe caps damage at exactly 1 HP when the hit would otherwise faint the target. For Ghost-types (immune to Normal moves), use Night Shade instead and watch the HP bar.

The damage of Night Shade is equal to the user's level.
How to get it. Level-up move on Ghost-types. Damage equals the user's level. That gives you predictable chip damage against Ghost-type wild encounters where False Swipe fails.

2Put the target to Sleep for a 2.5x catch bonus. Sleep is now the strongest status multiplier in the catch formula at 2.5x, beating the 2x value it held in Gen III and IV. Four primary sleep moves, ordered by accuracy:

Spore puts the target to sleep.
How to get it. Level-up move on Foongus and Amoonguss. Smeargle is a Hidden Grotto find in BW2. 100% accuracy makes Spore the gold standard once you can access it.

Sleep Powder puts the target to sleep, if it hits.
How to get it. Level-up move on the Petilil/Lilligant and Cottonee/Whimsicott lines. The two lines split between Black and White versions in BW, so you may need to trade or wait for the National Dex post-game to access both. Cannot be learned via TM.

3Throw the right ball. The right ball depends on the situation, not on rarity. Walk through the questions below in priority order. Stop at the first YES.

Walk through these questions in order and stop at the first YES — that is your ball. If none of the questions apply, throw an Ultra Ball.

1
Is it turn 1, before any other action?
YESQuick Ball5x bonus
Throws on the first turn of battle only. After turn 1 the bonus disappears.
2
Have you already caught one of this Pokemon (registered in your dex)?
YESRepeat Ball3x bonus
Triggers on species you have already added to your Pokedex as caught.
3
Is the wild Pokemon a Water-type or Bug-type?
YESNet Ball3x bonus
Active against Water-type or Bug-type targets, secondary types count too.
4
Are you battling while surfing or fishing?
YESDive Ball3.5x bonus
Triggers when the encounter is on water tiles or via a fishing rod.
5
Is the in-game clock at night, or are you inside a cave?
YESDusk Ball3.5x bonus
Active during nighttime hours and inside dark interior areas.
6
Has the battle dragged on for many turns?
YESTimer Ball~4x bonus
Multiplier climbs each turn and reaches its 4x cap near turn 30. At turn 10 the bonus is only around 2x, so this is a long-stall tool rather than an early-fight pick.
If no question above applied
DEFAULTThrow the strongest plain ball in your bag
Ultra Ball2x bonus
Great Ball1.5x bonus
Poke Ball1x (no bonus)
Use the strongest tier you have. Ultra Ball is best, Great Ball is mid-tier, Poke Ball is the basic fallback when nothing else is available.

Skipping any step costs you catch odds. The full sequence is weaken HP, apply Sleep, then throw the situational ball. Gen V is the first generation where critical capture exists, so a fully prepped throw can sometimes succeed on a single shake check.

Generation V introduces critical capture: when your Pokedex completion is high enough, the ball runs just one shake check instead of three, and that check is much more likely to succeed. The chance scales with how many species you have caught (not just seen). Filling out the dex pays off in future catch attempts. This was the headline catch-mechanic addition in Black and White.

Black 2 and White 2 expand the regional dex significantly compared to the original BW. More sleep-move users are available without National Dex unlock, including Breloom in a Hidden Grotto for Spore access. Hidden Grottoes also reintroduce Pokemon like Drowzee for early Hypnosis access, which BW1 gated behind National Dex. Critical capture carries forward unchanged from BW.
