tagline=Lucario and Mew replaced by Dungeon of Mystery rescue teams
The Japanese intro for the Battle Frontier saga has unexpected updates made to it. }}
With the airing of [[bp:AG152|AG152]] in Japan, viewers were surprised to come across an unexpected update to the intro sequence.
* [[bp:Jessie's Dustox|Jessie's Dustox]] makes an appearance in the Team Rocket segment. However, there is no longer a blur of [[bp:Manyula(Pokémon)|Manyula]] rushing
through the screen.
* Replacing the scene of [[bp:Lucario(Pokémon)|Lucario]] resting on a tree limb and [[bp:Mew(Pokémon)|Mew]] flying by
, is a new scene based on the boxart of the games ''Pokémon: Dungeon of Mystery Red and Blue'', which went on sale on the same day this episode aired. While the Red version's boxart is closely depicted, the same cannot be said for the Blue version's boxart, with [[bp:Ash's Pikachu|Ash's Pikachu]] and [[bp:Ash's Corpish|Corpish]], and [[bp:May's Squirtle|May's Squirtle]] and [[bp:May's Munchlax|Munchlax]] appearing instead of the original characters (specially-equipped Pikachu, Squirtle, Totodile and Mudkip).
It is further speculated that the sequence will eventually be updated in honor of both the ''Pokémon Ranger'' game and movie.
Also deserving of note is that prior to the first scene of the episode, there was a countdown featuring altered clips from [[bp:Advance Adventure|Advance Adventure]] and a clip from [[bp:Pokémon Symphonic Medley|Pokémon Symphonic Medley]]. It is as of yet unknown what this is meant to mark.
