Reason: SwSh weight thresholds
Generation II to Sword and Shield
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.
|-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 used on an Ultra Beast, the catch rate modifier is instead always set to 0.1×.
In Pokémon Crystal only, there is a glitch that causes the retrieved weights of Kadabra, Tauros, and Sunflora 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, correctly giving them a -20 catch modifier.
In all games except Pokémon Sun and Moon, 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.
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 item.

In Teddiursa's Picnic, Silver received a Heavy Ball from Kurt, crafted from a Black Apricorn he had given to the man earlier. He used the Ball in the next round to catch a wild Ursaring that was attacking Gold and Maizie.

- Main article: Heavy Ball (Next Destinies 88)
The Heavy Ball is an Item card in the Pokémon Trading Card Game introduced during the English Black & White Series (the Japanese BW Era). First released in the Next Destinies expansion, it was reprinted in the Japanese Master Deck Build Box EX before being reprinted worldwide for the BREAKthrough expanstion. This version was included in the Japanese The Best of XY 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.
- 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 Beldum and the guardian deities.
