Karl is the Ultimate Figure Skater. 

His voice is on the deeper side, and it is quite smooth. He has a little bit of a Swedish accent, he may mispronounce words or his accent might make a few of them hard to understand. However, he can have a British or American accent.

Karl has a very complex personality. He has his outside persona when he's performing and out in public. And then there's his inside persona, like around family and friends.

His outside persona is very bright and bubbly, he tries to be as nice as possible to people. He tends to have a really big sweet spot for kids though and is therefore really nice to them. He can get annoyed but it's only on rare occasions, for example when people are being extremely rude to him or his friends or when he sees someone else being mistreated

His inside persona is more calm and relaxed. He bit of a hermit and doesn't go outside or socialise a lot, but he is still a nice guy, he just doesn't have as much energy. He still has a huge soft spot for kids, especially his younger brother.
