User blog comment:Echo 1/Samus vs. John 117. Who'd win?/@comment-206.213.170.10-20101206182235

Well, considering that Master Chief is vulnerable to plasma weapons, Samus can use the Plasma Beam. Not to mention, the Chief's armor is made of titanium, so not only will his armor not protect him against the Plasma Beam, but the Power Bomb would just do fine to vaporize the Chief. Really, there are so much more characters out there besides Samus who can best the Chief.
