Hm, I was talking to my friend who used to play Pokémon Crater with me on MSN and he sent me a link to a picture of Arceus, telling me this Pokémon was being called the God of all Pokémon. My first thought was me wondering whether or not he was joking and my second was me realising I wasn't impressed by the appearance of the so-called God. The third thing I thought was what happened to Mew? It was, after all, the Original One. The ancestor of all Pokémon. To this day, I still don't have an answer for that question.
Long story short; Arceus did not entertain me.
