I like COSMIC better than SPACE. I'd go with either SOUND or SONIC.
I'd also go for a MYSTERY type. Not weak or strong to ANYTHING. But have multiple many more variations of abilities that alter type advantages in various ways.
Maybe an ELEMENT`AL type. Any Pokemon that are either non-physical or only part physical would be at least part ELEMENTAL type. --- GAMERTAG: Casperstar X "For those of you wondering whether the above made sense, you've just answered your own question."
