Master Chief (Halo Series)
While there are certainly reasons for Master Chief’s overwhelming superiority to his peers and enemies in the Halo series, it’s hard not to call someone designed to be a one-man army anything other than overpowered.
The last remnant of an experimental unit of soldiers, the Chief is host to cybernetic and biological enhancements which allow him to outclass most any other adversary he could meet on the battlefield.
He can regenerate wounds in seconds, wield massive weaponry from across cultures and races on the fly, and beat down enemies twice his size in one blow.
Likewise, he has the help of Cortana, an immensely powerful AI, through most of the series, allowing him to bypass almost any technological barrier or hurdle the enemies that were placed in front of him.
All of that’s just what players can do themselves, too.
Throughout the Halo series, the Chief has also been shown to be capable of plenty of other absurd feats, including surviving a free-fall from space back down to Earth.
It’s little wonder that enemies like the Grunts flee from him on sight, and raises the question of why more don’t do the same.
