Nice Pokémon, but they look more like Dark-types to me for some reason...
And there isn't that much difference between them...but they are still good. I suppose there isn't much difference between Poochyena and Mightyena...
I like the idea of Psychic-type Remoraid and Octillery. I think Psychic-type Delta Species are somewhat better than other types, mainly because they're not as common. The only Delta Psychic-types I know of are Espeon (DS) and Omanyte/Omastar (HP).
