Personally, I would want Bastila back, but since she's not an option :angry: :
1. Canderous - tough, mean, need a good fighter.
2. Carth - he can disappear. I don't need him around with his attitude.
3. Juhani - nothing special, she can go.
4. Jolee - funny, old man. He would be cool, but not as a companion.
5. Zaalbar - nothing special here either, he can go.
6. Mission - she should be 19 in KOTOR 2. Hmmmm, new love interest? :D
