I actually made that post with the trillion in mind. This is Pokemon, not real life. Do you remember when Pikachu fried Brock's Geodude with a thundershock? Or when he deafeated both Pryce's Piloswine and I forget who's Rhydon with thunderbolt just because he "aimed" it? Just because real life says electricity doesn't affect ground, doesn't mean GF says it doesn't.
The anime has nothing to do with the games. If it did, there would be a move called Thunder Armor and Grotle would be able to heal itself by eating its own Energy Balls.
It's not only real life that says electricity can't affect ground - it's the games too. Talk about not making sense...does it make sense that a Level 100 Raikou using Thunder on a Level 1 Trapinch after 6 Calm Minds can't do a single point of damage to it, just because Trapinch is a creature that lives in the ground? No, but those are the parameters that have been set. Like I said, I would love if Tera Voltage let you hit Ground types with Electric moves, but there's no real reason to believe it would. If I invented an ability called "More Powerful Earthquakes" (yeah, it's a terrible name, just bear with me here) would something about that name imply that it would let a Pokemon hit Flying types with Ground moves? No. They'd still just be able to Fly above the Earthquake, no matter how strong it is.
Yeah , sure , Mew is the ancestor of all pokemon , then came Mewtwo who was a robot rival and claimed he was so pr0 and the father of all pokemon too , then came Arcues claiming he was the creator of all pokemon....
I think you're mixing up the anime and games. Mewtwo never claims to be the father of all Pokemon in the games. If he does so in the anime, we know he's just lying, since we see him being cloned. Animated villains tend to brag a lot. You can't take everything they say seriously.
I think Arceus created the world and most of the legendary Pokemon (Palkia, Dialga, Groudon, Kyogre, Darkrai, etc.) but Mew is the ancestor of all the normal Pokemon. It makes sense, since Mew can learn almost every move, including Transform. The Pokemon mythos isn't exactly set in stone though, so like you said, anything could happen. I'm just interested to see how Reshiram and Zekrom fit into things...are they above Arceus in the Poke-pantheon, or below him?
