Enter may have failed to defeat the Go-Busters, but he did have one last resort. During the final fight in the sub dimension, in a last ditch effort, he launched all the Metavirus cards, old and new, along with data replica's of some the Messiah cards into another dimension. Figuring the random dimension wouldn't have Enetron, he programmed the cards to convert whatever energy they could find into Enetron, as well as setting them to activate on their own when they collected enough energy, while programming the Messiah cards to seek out what they originally infected. What he didn't know... was that the dimension... contained something... far worse than humans. It contained... ponies.
