The Fall of Albino Lugia

The Fall of Albino Lugia is the longest special/movie to date. Two ghosts arrive in the Lugia Lands one night, and they make their way to the top of Sky Mountain, where Albino Lugia is asleep. They wake up Albino Lugia in the process, and the ghosts suddenly possess him, taking complete control over him. The next morning, Albino Lugia is nowhere to be found and one of the most complex and difficult searches ever to happen occurs.

This is also the first special/movie to include the most amount of characters. The entire Lugia cast appeared, as well as the Eastern Lands Charizards, Mega Rayquaza, Mega Latios, and much more.
