Pokemon, that is to say cartoon and playing card game, would be in itself non-demonic only at first glance. I myself am surprised how many people still play them considering it is a dying fad.
Let's go over what we do know about them...
1. Pokemon was created by Wizards of the Coast. The same creators of D&D/MAGIC the Gathering, which in most christian sects is known to be totally demonic and also addictive for adults.
Nope. Pokemon is published and owned by the video game company Nintendo and was created by Satoshi Tajiri in 1996. The Pokemon Trading Card Game was first published in North America by Wizards of the Coast in 1999. However, with the release of Pokemon Ruby and Sapphire Game Boy Advance video games, The Pokemon Company took back the card game from Wizards of the Coast and started publishing the cards themselves.
2. The name stands for Pocket Monsters.
3. The objective is to "collect them all" to become the most powerful "trainer" which caused mass addiction and craze on it's initial release.
4. Massive use of Wiccan Elementals in the battles. (Earth, Wind, Fire, Ice, etc.)
The idea of elements comes from classical Greece, millenia before Wicca, which was created in the 20th century. Moreover, Wicca has nothing to do with elementals. Wicca involves five elements, not elementals: air, fire, water, earth, and aether, and they are seen as symbolic.
5. Cartoons are filled with "cursing",
I doubt there is cursing on a Saturday morning cartoon.
"spell casting" and other non-average-fiction tones.
Pokemon is not an innocent childs game. Nor are the characters in themselves demonic, rather, the combination of innocent cartoon and game merges with the occult to produce the deception and dangerous demonic influence. It is a predecessor to other RPG and card games which will spiral the user deeper and deeper in his interest of the supernatural.
Classic slippery slope.
Of course these powers are not of God, so they can only have one other source...
Fiction! (Sorry to disappoint you. Pokemon are not real.)
