If Pokémon Talked: Generation II
Terraptous for Ledyba/Ledian (Male)
Ledyba is a Bug/Flying type Pokémon. It's a very timid and gentle Pokémon. It also hates the cold weather. When the weather gets cold, a group of Ledyba will huddle each other up to keep warm. A shy but kind of energetic high pitched voice would suit this Pokémon.
Ledian is Ledyba's evolution. Its star pattern on it's back has been improved. The spots on its back will grow larger or shrink into a slightly smaller size depending on how many stars are out in the sky. Even if evolved, it's still not so good at fighting. The voice for this Pokémon, I would expect the voice to be more energetic, and more enthusiastic. Also it still has a high pitched voice, but matured up a bit.
Ledyba: I don't think I can do this without my swarm. But I guess I'll try. It's not gonna be easy though.
Ledian: This is the perfect night. This night has brought good luck to me. Just look at those stars, and how bright they shine. I hope good luck will be brought to everyone else in rough times like this.
