Another vote for the Ghost... he is just so simple and only want company... and ... what a nice company!... Besides, he is a good help killing one enemy for sure in battle... i always wanted to take a ghost with the group for the entire game xD...

Vicks and Wegde: just a pair of cowards letting a girl going in front putting her in danger just to be safe themselves... Cowards... ¬¬'
Banon: Nice, he had a good thought against the Empire... but... let's be frank... he sucks in battle!... the only thing he can do well is healing, but mn... u don't need healing all the time, sometimes u need a hand with fighting... ¬¬' ...And it's worst!... he also need u to be taking care of him... lol... he is too grown up, he already could be in age for taking care of himself! ...he was a waste of time for me in battle...
General Leo: Too cliché for me... The good boy with a great charge at job, with all the money and all the things that could make him happy... anyone can be good and the greatest 'benevolent' in that case!... ¬¬'

=P
My opinnion... i like the ghost...
