Soul Calibur poll of the week: favorite guest character

Guest characters have been a running tradition in the Soul Calibur series for a long time now, and since their introduction in Soul Calibur 2 have been a point of contention for many longtime fans of the series. Some have complained that they are too unbalanced for competitive play and clash with the aesthetics of the series' original characters. Other players however (like myself) were introduced to the Soul Calibur series after learning of the inclusion of third party characters in a Soul title, thus creating new fans and broadening the appeal of the series.

In this thread, I want to ask: who is your single favorite guest fighter in the Soul Calibur series overall? Please vote!  

NOTE: Guest fighters only available thru character creation like Devil Jin weren't included, and I didn't include Lloyd Ivering either since he appeared in a brawler spin-off and not a main series entry or fighting entry. Hope you guys understand.
