The Love Ball (Japanese: ラブラブボールLovey-Dovey 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 against a Pokémon of the opposite gender to the Trainer's Pokémon.
When used from the Bag in a wild encounter, it attempts to catch the wild Pokémon. Starting in Pokémon HeartGold and SoulSilver, if the wild Pokémon is the same species as but the opposite gender to the player's active Pokémon, it has an 8× catch rate modifier; otherwise, it has a 1× modifier. If used on an Ultra Beast, the catch rate modifier is instead always set to 0.1×.
In Pokémon Gold, Silver, and Crystal, while it is intended to be more effective against Pokémon of the opposite gender, due to a glitch it has an 8× catch rate modifier against Pokémon of both the same species and gender as the player's active Pokémon, having a 1× modifier otherwise.
The Love 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 Trouble's Brewing, it was shown that each of the Kimono Sisters kept their Pokémon in an Apricorn Poké Ball. Although Koume's Flareon's Poké Ball was not shown, the pattern on her kimono indicates that it would be a Love Ball.
