Lugia

Boasting the title as the Great Wall of the Pokemon world for four consecutive generations, Lugia's titanic defenses and exceptionally high Speed allow it to stall out a large portion of the Ubers metagame, ranging from the legendary Extreme Killer Arceus and Rayquaza to more obscure threats such as Venusaur. Unlike most walls, this flying beast is able to take both physical and special hits like a champ, sometimes even stalling out powerful STAB super effective hits with the help of Reflect or Light Screen. However, Lugia is not without flaws; it is not only total Spikes bait, but is also completely powerless against bulky foes. With newcomer Kyurem-W joining the metagame, Lugia might not enjoy its life as a wall just like it could in the past.
