Boosts its Speed in sunshine.
Chlorophyll is a very common ability for grass type Pokémon. When a Pokémon with Chlorophyll is in sunny weather, its Speed stat is doubled!
This can make a significant difference in battle when the user already has a high Speed stat to push over the edge. If used on a lower speed Pokémon, well the effect might not be as noticeable but will still be helpful!
