Despite how cool
Light could be, if there's a new type, it should be entirely unique and stand out far from any other type - a type that would actually diversify the world of Pokemon, rather than being an "alternative" to any other type.
I think a really great type could be:
Sound
Pokemon that are highly attuned with vibrations and the connection between all things would be "Sound" Pokemon, a sort of cross between Electric and Psychic, conceptually. The stats are as follows:
Weak to: Psychic, Fire (both disrupt the molecular connection between all things)
Strong against: Rock, Ghost, Flying (Rocks can be shattered by vibration; Ghosts, as negative forms of energy, are overwhelmed by the "sound" vibration; and Flying is harmed by vibrations through the wind)
Resist: Dragon, Electricity (Dragon's roars and Electricity create vibrations, which do not effect
Sound much, as that is what it is based around).
Pokemon that could be edited to be
Sound:
- Whismur
- Loudred
- Exploud
- Voltorb
- Electrode
- Jigglypuff
- Wigglytuff
- Igglybuff
- Aipom
- Ambipom
- Chingling
- Chimecho
- Bronzor (change Psychic)
- Bronzong (change Psychic)
- Chatot (change Normal)
