If Pokémon Talked: Generation II
KittyLuv090 for Mareep/Flaaffy (Female)
Mareep is an Electric-type Pokémon. These Pokémon store electricity in their woolly coats. Touching the wool can cause a painful shock. It also seems a bit of a pacifist. A high pitched voice with occasional sheep-like vocals would be a good fit for this Pokémon.
Flaaffy is the evolved form of Mareep. It has also lost half of its fur, because it has stored too much electricity. However, its bare, rubbery skin protects it from the powerful electricity left in its wool. Since its the evolved form, and it seems that it has more spirit for battle, a slightly lower voice for the Pokémon would be a good fit. It now only has a rare amount of the sheep-like vocals.
Mareep: My woolly coat makes me all fluffy and warm! But be careful not to stroke it. You can get shocked badly.
Flaaffy: Well, since I'm rubbery, whatever gives me a static shock bounces right off me.
You can still got shocked if you stroke the fluffy part of my head. Just because I have less wool, doesn't mean I develop less electric shock!
Oh, I forgot to let you know at the start, that I have decided to cast you for a lot of roles you've auditioned for here! :)
