I think there's no more translated character names because of trademark issues... It's a pity in my opinion! When I was a kid, Spider-Man was still Hämähäkkimies in Finland...
Anyway, I just had to translate G4 Mane Six' names into Finnish and ended up laughing out loud
I think you'll find these strange enough! And all you Finnish pony people, can you think of better ones?
- Fluttershy: Ujo Lepatus
- Rainbow Dash: Sateenkaarivilaus
- Twilight Sparkle: Iltaruskon Kimallus
- Rarity: Harvinaisuus
- Pinkie Pie: Vaaleanpunainen Piiras
- Applejack: Omenaviina
(Oh dear, I've got too much time on my hands!)
