so, I'm a huge fan of Pokemon, and the fact that there's 17 types of pokemon bugs me.
so I've come up with the next type of pokemon: Light.
ATK:
2x: Dark, Ghost, ???
1/2x: Grass, Fire, ???
0x: ???
DEF:
2x: Dark, Rock, ???
1/2x: Ghost, Normal, ???
0x: Psychic, ???
yep!
Now, I can't think of all the strengths and weakness, I need some help with that, but I think this could work!
and, for Gen VI, the main Legendaries would be a Dark type and a Light type. The Dark one looks like the moon, and the Light one looks like the sun! have to think of a Trio that goes with that theme, but that can't be hard.
and yes, i know they used the sun
