Leviamon is a pretty powerful digimon and his attacks will definitely deal some serious damage to his opponents. Wailord is skilled in his own right as well, but he lacks maneuverability and won’t be able to dodge very easily. Wailord has a lot of great abilities which will eat away at Leviamon’s health, but Wailord’s defense will not hold out as long. Leviamon wins.
