2 of the space marines have power fists and pistols. The other one is equipped with a pistol and chainsaw sword.
Lysander comes with a power fist, his hammer, and a shield.
The Chief comes with 2 grenades, a BR, and a pistol.
Who wins?
I think Lysander would eat the Chief. If you know anything about 40K you should know this.

Not even a contest, the SPESS MEHRENS would Shrek Master Chief inside out and around the block. Chief would have to shove the Grenades inside of a Space Marine's armour to even have a chance of hurting them. One blow from Lysander's hammer would pulp Chief, Mjolnir or not. The powerfist would probably do the job as well. That's not to say what kind of havoc a boltgun would do to Chief. It's so onesided that it's almost cringeworthy lol.
