It was hard to choose from the main four (Zidane, Garnet, Steiner and Vivi), but I went with Zidane, with Garnet a very close second. So close, her's and Zidane's spot could easily be changed around. Zidane was just a fun character, especially when compared to the super serious Cloud and Squall from the games before. He was very useful in battle, too. His Thievery ability is incredibly useful if you power it up. Garnet, on the other hand, she was a great character. Down to earth, beautiful, nice and just loveable, in my opinion. I felt she made the game what it was.
