Since its initial tease in Japanese theatre showings of the latest Pokémon movie, and subsequent marketing images with a better look, there's been huge interest in the 'green blob' Pokémon. Part of the allure is in the mystery, along with thoughts drifting to whether it'll play a prominent role in the overarching lore and, potentially, feature in future game releases.

After very little information some salvation is on the way. A trailer for a Mega Evolution special in the Pokémon XY anime series - which will apparently close off its own particular story arc - will feature the new 'mon; it seems to have a fairly prominent role in the tale.

We'll likely know more about its backstory soon, then, which is sure to get fans chatting when it happens. What are your current theories on 'the blob'?
