Weavile was seen quite often in Paul's appearances, helping Paul catch his Gliscor, sparring with Torterra and battling Ash's Staraptor. Weavile put up a good fight, displaying speed and some powerful attacks as well as enough defensive strength to endure the extremely effective Close Combat but in the end Staraptor managed to win despite its type disadvantage.

Weavile appears to be one of Paul's weakest Pokemon, as it has never been seen defeating an opponent, even when it has type advantage. However, it must have had many victories off screen, because Paul would have released it otherwise.
