The Heavy Ball (Japanese: ヘビーボール Heavy Ball) is a type of Poké Ball introduced in Generation II. It can be used to catch a wild Pokémon, being more likely to succeed the heavier the Pokémon is.
It is one of Kurt's signature Apricorn Poké Balls, and is made from Black Apricorns.

====Manual activation====
When used from the Bag in a encounter, it attempts to catch the wild Pokémon.
The Heavy Ball is more effective against heavier Pokémon and less effective against lighter Pokémon, varying based on several discrete weight groups. The modifiers used are listed below.
Modifier	Games 	Games 	Games
Modifier	 	 	
-20 	225.5 lbs. (102.3 kg) or less 	451.3 lbs. (204.7 kg) or less 	220.2 lbs. (99.9 kg) or less
±0 	225.8 lbs. (102.4 kg) – 451.3 lbs. (204.7 kg)	N/A 	220.5 lbs. (100.0 kg) – 440.7 lbs. (199.9 kg)
+20 	451.5 lbs. (204.8 kg) – 677.0 lbs. (307.1 kg)	451.5 lbs. (204.8 kg) – 677.0 lbs. (307.1 kg)	440.9 lbs. (200.0 kg) – 661.2 lbs. (299.9 kg)
+30 	677.3 lbs. (307.2 kg) – 902.8 lbs. (409.5 kg)	677.3 lbs. (307.2 kg) – 902.8 lbs. (409.5 kg)	661.4 lbs. (300.0 kg) or more
+40 	903.0 lbs. (409.6 kg) or more 	903.0 lbs. (409.6 kg) or more 	N/A
If the modified catch rate exceeds 255, it is instead set to 255.
If used on an Ultra Beast, the catch rate modifier is instead always set to 410/4096× (~0.1×). The catch rate used in the calculation is still modified as normal by the Heavy Ball, however.
In only, there is a glitch that causes the retrieved weights of Pokémon whose index numbers are divisible by 64 (, , and ) to become junk data that are, in turn, interpreted as massive weights, causing these particular Pokémon to receive the +40 capture modifier. In Gold and Silver, these Pokémon's weights are retrieved correctly, giving them a -20 catch modifier.https://github.com/pret/pokecrystal/blob/master/engine/items/item_effects.asm#L763https://www.dragonflycave.com/mechanics/gen-ii-capturing
In , the ±0 and -20 modifiers were supposed to work like Generation II's, but the -20's modifier instead checks if the catch rate is less than 1024, rather than the weight (internally, weights are stored as tenths of kilograms), which is always true, so when the ±0's "less than 204.8 kg" check is passed, -20's will always be as well.https://www.dragonflycave.com/mechanics/gen-iii-iv-capturing#capture-rate
In all games except , if using the Heavy Ball would cause the wild Pokémon's catch rate to become negative, it is instead set to 1. In Pokémon Sun and Moon, it is instead set to 0, making it impossible to successfully catch such a Pokémon with a Heavy Ball in those games.
If the player uses the Heavy Ball on a transformed wild Pokémon (either from or ), its weight after transformation is taken into account instead of its original weight.
The Heavy Ball cannot be used in situations in which Poké Balls cannot be used, such as in wild battles with two or more opponents currently present or against a trial Pokémon. If used in a Trainer battle, the opposing Trainer will bat the ball away, wasting the turn (as well as the ball prior to Generation IV).
====Held item====
 fails if the user is holding a Heavy Ball.
In only, Heavy Balls cannot be held. This is to prevent them being held by a Pokémon traded to , where the item does not exist.

==In the TCG==
The Heavy Ball is an in the Pokémon Trading Card Game introduced during the English Black & White Series (the Japanese BW Era). First released in the expansion, it was reprinted in the Japanese before being reprinted worldwide for the expanstion. This version was included in the Japanese compilation.
When a player uses a Heavy Ball, they are allowed to search their deck for a Pokémon with a Retreat Cost of 3 or more, reveal it, and put it into their hand. The user shuffles their deck afterward.
==Trivia==
* In Pokémon Sun and Moon only, a Heavy Ball will always fail to catch a Pokémon whose weight is less than 220.46 lbs (100.0 kg) and whose catch rate is less than or equal to 20. This is because the game will set the catch rate to 0 when the catch rate becomes negative due to the -20 modifier that is applied. The only catchable Pokémon that this affects are and the guardian deities.
* Starting in Generation VI, the Heavy Ball gained two extra blue protrusions on its back, mirroring the two featured on its front.
