Don't you know anything titus? Tatsamaru may be human but that is not a weakness. For one, Gray Fox's cyber technology is not perfect. You can see it in the game on several occasions. For one his stealth is broken, he screams. But then again, it might not be a problem with his new body at all. It very well maybe he doesn't want to live again. If he has a death wish, then most definately Tatsamaru would win.
