Hundreds of years ago, there have been rumors of every legendary Pokemon going missing throughout the regions. A trainer who went by 'Echo' captured and befriended every legendary and now travels in disguise. Echo travels with her main Pokemon, Sceptile, who is shiny. Everyone attempted to catch the Treeko he evolved from, but none could. Echo was only a little girl when her father died. His ancestors passed all the Pokemon down through generations, making their way to Echo. Every trainer of these legends has named themselves Echo to remind the world that they will never die, nor give up. Each of Echo's legendary Pokemon has special places they go, organizing them on her belt and her pendant from region and time caught. Victini was on the pendant, along with Zeraora, Ho-Oh, Marshadow, and Sceptile. Though Sceptile never returns to his Pokeball, it has a special place. Sometime later, Echo was identified as Koffic Serulea. Without a place to hide, she is forced to the ultra wormhole, where she finds Ash and his friends. Seeing Nihilego being harmed, she rushes to save the ultra beast. Using her legends, she will soon be forced to move to a new hiding place, or so she thought.
