I would like to make a valid, or as some would prefer it, important, point regarding!
Thanks to the Metroid game Metroid: Other M, we can now acknowledge the fact that Samus, despite her emotional and very touchy background story, is a calm and social person, who could never be a tsundere, if so her life depended on it.
Therefore, it's rather pointless to either portray, or fantasize about, her being a dere-type female.
Samus won't be a woman, who would use her female/personal pride as an excuse to become/act abusive.
Samus is a stoic, 6'3" feet tall woman with the bodybuilder figure of an average female athlete, on a weight of 90kg/198lbs, and has a sense of honor, which allows her to combine her military training and background with her nature as a bounty hunter, to be a Steve Rogers-esque patriot.
