Isshu League Tournament

Ash's Leavanny participated in the Isshu League Higaki Tournament. It was matched up against Stephan's Sawk in the third match up of the third round battle. Iris noted that Ash Ketchum had decided to fight power with speed as Stephan's Sawk had a hard time landing hits against Ash's Leavanny. It wasn't until Stephan's Sawk was able to block one of Ash's Leavanny's X-Scissor attacks that it was actually able to start hitting. After taking some significant damage, Ash's Leavanny's ability Swarm was activated and thee power of its Bug type moves increased. Ash's Leavanny's String Shot gained a lot more strength and Stephan's Sawk was unable to break through with Bulk Up until after multiple X-Scissor attacks had weakened the string enough. Stephan's Sawk then with one large leap into the air, finished off Ash's Leavanny with a powerful Karate Chop.
