Lugia is a Pokeball Pokemon and, as Shadow Lugia, a boss for Smash Bros. Clash. As a boss, his battle theme is the Weather Trio's theme from Pokemon Ruby, Sapphire, and Emerald. As a Pokeball/Assist, he roars loudly and unleashes the attack Dragon Pulse much like he did in Melee and Brawl. When Lugia makes a roaring sound, it sounds like a mix of Nefarian's roar and a T-Rex's. Like the Shadow Hunter enemy, Shadow Lugia was spawned through corruption, thanks to the monsters of the night covering the dragon's entire body, transforming him into Shadow Lugia.
