After the events of the last episode when Bianca leaves the group behind her, Cedric Juniper came out of the cave in bad shape and collapsed. After he feels better, Cedric officially introduces himself and explains what happened. Apparently he found some ruins and needed help to investigate. Ash and Iris were more than excited to help when they found out the temple had a link to the legendary Pokémon Zekrom by the hero as so as his heart becomes one with the Pokémon. As they make their way through various trap sets as Cedric explains his rules, they've got themselves into trouble when they see one Sigilyph blinded with anger when Cedric took the Golden Dark Stone and encountered a lot of Cofagrigus ambushing out of hiding. Will our heroes survive the ordeal?
Though in a fantasy, This is Zekrom and Reshiram's second appearance in the anime series with the first being at the beginning of BW001: In The Shadow of Zekrom!
This is the second instance where Ash and his friends "Blast Off". Although they fall back to earth.
The soundtrack title theme of Zoroark; Master of Illusions can be heard the second time when Ash and co. were about to fall to their death as they made their hearts become one with the Pokemon. First was BW064: Crisis at Chargestone Cave!
Almost every Pokémon Ash and co. have seen up to this point has been featured in flashbacks.
The Sunglasses Krokorok doesn't appear until the end of the episode.
There were three cave entrances each with the head of a Darumaka, a Krokorok and a Golett.
The Darumaka head breathed fire.
The Krokorok head slammed shut.
The Golett head was the real entrance.
Like the movie called "The Great Escape", there were three tunnels that are similar to the ones they've picked. The tunnels in the film that are similar are "Tom," "Dick," and"Harry". And tunnel named Harry was the real escape route.
The opening soundtrack of Zoroark: Master of Illusions was used the second time since 2 episodes earlier.
Stan Hart (the original Voice Actor of Professor Oak) returns in this episode to voice Cedric Juniper.
