If your into slaughtering huge amounts of people then I recommend unlocking him. His storyline is very straight forward, hes bored so he goes straight into other peoples wars just for the fun of it. Hell 2 characters (I won't ruin the story by saying the names) even come back from the dead just to fight him His movements are not only fast, but incredibly powerful and after you get him to level 50 all of his stats are 1000. His special seems to give him a boost of roids and last one hell of a long time. I find his entire story to be humorous and well worth unlocking.
