Sound and Light Types

zutaradragon Introducing 2 new Pokemon types! Anyone who's been following along knows that this dex allows 3 types, and some pokemon will be gaining these types tacked on to their original types in this region! (for instance Chattot, the Jigglypuff, Whismer and Nuibat families will gain sound) Some pokemon attacks will also be reclassified (Sing and Echoing Voice would be made sound for obvious reasons as would Flash be made a light move. Just as some examples) Update: (thank you, HoopsandHipHop, for doing the weakness resistance thing and also for bringing up things I already said about the types) ~Sound Type~ Strong against Flying (because air is how sound moves) Strong against Ghost (because you're manipulating the air with sound to expose them. Also because using sound to find ghosts is pretty common) Weak to Ice (Sound does travel was well in cold air) Weak to Electric (Technology manipulates sound however it wants) Resisted by Ground (Because sound doesn't travel well through it) Resisted by Steal (Because sound doesn't travel well through it) Still need to work on Light Type though I feel like Light and Dark should be equally matched, as 1 can not exist without the other (And it seems to have been decided that if this region had games they would be called Light and Dark). Perhaps it should be good against Ghost types but I have no idea what it would be weak against...help...please...
