Raziel of the Soul Reaver series is an outstanding video game character for a few reasons. Most involve the fact that he is vastly different from mainstream protagonists in video games.
1) Anti-heros are awesome. Too many heroes play nice. As Raziel, common methods of dispatching opponents are impalement, burning them or hitting them so hard they explode. Afterwards you can eat their souls. All his actions are justified, at least to his mind. For instance, the aforementioned methods of killing are usually the only way to permanently put down opponents hindering his mission. Arguably, Raziel often does the wrong thing for the right reason.
2) Raziel is relentless. He seeks revenge for his murder hundreds of years after the fact. Also, he is one of the very few video game protagonists that cannot be killed despite efforts from the opposition. If you run out of energy while playing you are banished to the spectral realm, but are free to return to the physical world via certain spots. Intimidation is an enemy who looks like an ticked off Batman corpse that keeps coming for you no matter how many times you take him out.
3) He’s unique and complex – Raziel starts out as a human. Once killed by his future self, he is resurrected as a vampire. Afterwards he’s executed by Kain and becomes a wraith. In the finale he willingly imprisons his soul in the eponymous Soul Reaver sword so Kain (yes, the guy who executed him) can use it to defeat the final boss. All this he does while speaking in Shakespearean English. “Complex” is understating this guy’s resume.
4) Cool arsenal – This is not an exhaustive list: a symbiotic wraith blade, telekinesis, intangibility, limited ability to glide, and elemental powers. Many abilities are gained mega man style (absorbed from defeated bosses) granting a sense of growing more powerful as you play.
5) Epic story – The story is as deep as you will experience in any medium. Too complicated to summarize briefly, the plot involves multiple time paradoxes and Raziel being manipulated by those more cunning or powerful than himself. The saga begins and ends within three games: Soul Reaver, Soul Reaver 2 and Legacy of Kain: Defiance. It’s a treat to see a good character in video games allowed to bow out gracefully with a contained story rather than be milked for endless mediocre sequels.
