I got to thinking about the Final Fantasy Characters that I used only when I had to. It's my list, so I don't need to justify it.

1. Edward (Spoony Bard) - FF IV

2. Locke - FF VI

3. Gau - FF VI

4. Cait Sith - FF VII

5. Irvine - FF VII

6. Eiko - FF IX

7. Freya - FF IX

8. Kimhari - FF X

9. Wakka - FF X

10. Fran - FF XII

11. Vaan - FF XII

12. Hope - FF XIII

There are other lame characters in the series, but I was just going for the playables.
