Snake-eyes is much more then a ninja. When he was 18, before he even became a ninja, he joined the army and every thing about him became classified... everything about him is classified even in top secret folders that are classified on there own rights. That's how bad ass Snake-eyes is.
The lowest member of COBRA have 2x human perception, duribility, strength and reflexes and Snake-eyes takes on platoons of them at once with out getting hit and while he does it they are shouting "HE IS TOO FAST! I CAN'T HIT HIM!" The Fred series guards are much better then the previously mention and Snake-eyes has been right in front of them with out any over and dodged their machine gun fire while running straight towards them (he was the only target by the way) and sliced their guns in pieces with one slice of a dagger! A DAGGER! The most impressive thing comic Blade as ever done was cut this one vampire like 4 times and let him slide apart... not that impressive when compared with Snake-eyes high end feats.
