Then star wars universe. Barely. Yuuzhan Vong "tech" would decimate forerunner fleets with Black Holes. Turbolasers outpower anything the UNSC and Covenant have, star destroyers are the same size as Covie ships, in a few standout cases they are bigger. Lightsabers would clash with a Covie energy sword, but that's a "blade" wielded by an enemy who can see the future and has honed his body to react to that power. Force Choke, force lightning, the ability to rip a covie super-carrier out of space and slam it into the ground with one's mind. The force is basically the "i win" button of the Star Wars universe. Spartan II's are the only things that could feasibly move fast enough to counter a jedi, but again the jedi would see it coming. Spartans also can not move faster than the speed of light, and if Expanded universe is canon then what we SEE in the films is the after image of light. Lasers travel at a certain universal constant, something along the lines of 299,792,458 metres per second. That's pretty fast, much faster than the fastest bullet or fastest plasma shot. Given Star Wars' universe has the Yuuzhan Vong, which are decidedly overpowered in every respect, Jedi, and Turbolasers which more than outdo the power output of the biggest mac gun and plasma accelerators of the UNSC and Covenant; the answer is obvious with any amount of math. The chief would probably still somehow survive because how else would Microsoft and 343i make any money off of him, but that's it.
