In episode 151, Jesse uses this card during his Duel against Jaden Yuki while the former was possessed by Yubel. He Special Summons this card from his hand as he had all seven Crystal Beasts on his field and/or in his Graveyard. This card then attacks and destroys "Elemental HERO Neos". In the next episode, this card attacks directly, but Jaden activates "The Flute of Summoning Kuriboh" to Special Summon "Winged Kuriboh". A replay then occurs and Jesse uses this card to attack and destroy "Winged Kuriboh". Jaden then learns from the Crystal Beasts that Jesse's soul is trapped within this card and advised him to destroy "Advanced Dark" before getting rid of this card. On Jesse's next turn, this card attacks and destroys Jaden's "Elemental HERO Storm Neos", Jaden then activates the second effect of "Instant Neo Space" to Special Summon "Elemental HERO Neos" from his Deck. Later Jaden activates "Super Polymerization" to fuse this card with "Neos" in order to Fusion Summon "Rainbow Neos". This action frees Jesse's soul and purifies this card back into "Rainbow Dragon".
In the second above-mentioned episode, this card appears within Jaden's thoughts when he notes that he could use "Grand Mole" to attack "Rainbow Dark Dragon" and return to its hand, but he then realizes that will leave him wide open for a direct attack by Jesse's two remaining monsters, and he will lose if those attacks succeed.
In episode 163, this card is seen in a flashback Zane has when he reminiscences on the last greatest Duel he ever had and washing up on Duel Academy after he lost to Jesse.
In episode 180, this card is shown in a series of flashbacks Jaden has when he notes to himself that a Duel isn't fun for everyone and that he knows that there is a serious responsibility in a Duel. In order to prepare for that, Jaden had to become more like an adult, but there is something that must not be forgotten.
In the Japanese version, this card's attack name is "Rainbow Reflection" and in the dub it's "Dark Rainbow Refraction".
