Havel the Rock, Elliot Rodger, and George Zimmerman could take on everything else and win.
Now before you say "BUT MUH OMNIPOTENT BEINGS!!!", let me give you three irrefutable reasons why they could roflstomp anything and everything.
1) Can't stop the Rock
2) Can't flim-flam the Zim-Zam
3) Can't dodge the Rodge
Havel and Zimmerman would be invincible, while Rodge would just insta-kill everything.
NOTE: Shrek is the exception to this rule. He would destroy them easily.
