If the opponent switches out the turn this move is used it&#39;s power is doubled. This effect does not work on opponent&#39;s leaving battle via the move <a href="http://pldh.net/dex/move/batonpass" class="linksred">Baton Pass</a>. If the opponent would use the move <a href="http://pldh.net/dex/move/uturn" class="linksred">U-Turn</a> and the user of Pursuit would go last then the user of U-Turn is dealt damage. If the user of Pursuit is faster than the U-Turn user then Pursuit will fail.
