Thanks everyone for the welcome!
True, but there IS more info that could make him multiversal or even beyond that.
Remember the episode in the Sinnoh Saga where Cyrus was going to use the lake trio to summon Dialga and Palkia? If you hear closely enough to what Cyrus says, he says something very interesting. I can even quote his exact words:
"Azelf, Mesprit and Uxie! Hear me now! Transfer your ancient powers to the Adamant and Lustrious orbs! And using the INFINITE Original Powers, connect Time and Space!"
Cyrus when saying this literally stated that the powers from The Original One (Arceus), are infinite!
And thats not the only thing im thinking about. If any of you watch the Kalos saga, do you remember the episode where Ash and his friends make a pit stop at Reflection Cave? In that episode, while they were exploring the cave, Ash and Pikachu got lost from everyone and while looking at one of the mirrors, another Ash pops up and snatches Pikachu, dissaperring into the mirrors. Soon after, Ash chases after the other Ash and after going through the mirror he stummbles upon a different alternate world. A world that's opposite of the world that Ash comes from. The evidence from this is that in this strange world, the other ash is a wimp and a weaak crybaby trainer while the ash WE know is a strong condfident trainer, Clemont studies magic and is very athletic unlike the real Clemont whos weak and invents machines, Serena is a hardcore serious battler whos even stronger than "ash" while the real Serena is kind and has a crush on our ash, Bonnie is a well respected child while our Bonnie is more jumpier, Pikachu loves to cause mischeft and is tough acting while our pikachu is the opposite, and the most striking evidence of all, Team Rocket in this strange world are heroes who help other people and pokemon! While our team rocket is......well you know already xD.
Also, while Ash was in this strange world, the alternate Clemont was explaining to him that Reflection Cave has a legend: that for every mirror the cave has inside it, is actually a portal to an alternate universe/world! Sounds like a big hint for multiverse XD
And one last thing. If anyone follows the Unova Saga, then you should know about a mythical pokemon known as Victini, the victory pokemon. This pokemon is capable of creating UNLIMITED energy within itself that it shares with others, granting them an absolute victory. Of course, Since Arceus created everything in pokemon that would mean he created Victini and gave it that capability. So wouldn't this mean Arceus also has infinite power?
Of course, this may only apply to Anime only pokemon or composite pokemon but i would still like to hear your imput on this possibility
