Definetly Samus. After all she is a strong female protagonist. Also she wore the power armor before it was cool. And yeah. Ive played so many Metroud games that she is my favourite nintendo character...or atleast in the top 3.
Then again... Other M kinda shot samus in the leg charactervise atleast... Lets...lets not get into that again.
Also didnt fox have a mediocreish adventure a few years ago? (Starfox Adventures)
