#4 – Terminator
This cybernetic organism, played masterfully by former champion bodybuilder Schwarzenegger, is actually a bad guy in the first of the three instalments in which he starred. However, it is Terminator 2 where our all-action hero truly shines as he manages to defeat a superior model, the T-1000, which is capable of taking the shape and appearance of anything it touches, always putting itself back together no matter what. Even after taking a right royal kicking, out hero still manages to hit his foe with a grenade launcher, destroying it as it falls into a vat of molten steel. A truly hard specimen.
