[quote name='elprincipe']Back on topic, I agree with those who correctly state that none of these characters (excepting Snake now) are in games with blood anyway, so it wouldn't make any sense.[/quote]Without any hesitation, I automatically disagreed with you and remembered LoZ: OoT, where Ganondorf spits out blood at the end. Sure, it was later changed to green, but it was initially red and blood. Also, Twilight Princess is T for Teen due to animated violence and blood.
So, strike Link out of the bloodless games category.
I'm sure there may be a couple of them that had some blood. Like Samus, for example, in the Metroid Prime series.
And honestly, I wasn't trying to be spiteful or prove anyone wrong. That immediately came to mind when I read your post.
