idea: grey attacks are meant to be associated with ghost SOULs.

firstly, only ghosts use grey attacks: napstablook and mettaton.

second, all attacks seem to have an associated SOUL - grey attacks have no associated soul and ghost SOULs have no associated attacks.

so it's possible ghost SOULs are grey, since you never see them.

note that mettaton EX's core is not his SOUL.
