Are you talking about the mysterious Pokemon at the end of episode 13"Mystery at the Lighthouse"? Well,I believe it’s a Dragonite that is bigger then normal.Sometimes Pokemon can be bigger then there regular size.But that is unexplained why are Pokemon like that.

After getting a life lesson from Bill and learning that there aremore than 150 known Pokémon species, the friends learn from Bill thatthere is only one Pokémon he is searching for, which he claims is thebiggest Pokémon ever. He says it is unique and that no one had everlaid eyes on it. One night, he says, he heard a strange noise comingacross the ocean from the Pokémon, but that was the last time he heardit.

So this Pokemon is big

As Bill is reminiscing, the same sound is suddenly heard, and a largefigure appears, rising from the ocean. It is revealed to be theoutline of a Dragonite. As it comes closer to the lighthouse, TeamRocket is shown scaling the cliff and, upon seeing the giantDragonite, they begin launching a barrage of missiles to try to catchit. This angers Dragonite, and it smashes the top of the lighthouseand begins to walk away. Bill calls out at it to stay, but to noavail.

You must be talking about a Ho-Oh
