Charge towards them firing your bolter and mowing them down with a chainsword.
Retreat to a Bunker and call a Drop Pod assault.
Charge into them with Rhino tanks.
Send in some good old Terminators.
Refuel and load up the ammo
Bless them with Holy water
Perform healing magic on them
Chuck meat at them and give animal sacrifices
I don't need no vehicle
The Holy Ghost
No animals can match me
I don't hate anyone in particular
Punch him a few times
Put a curse on him
Viciously torture him with sharp things
'Accidentally' push him off something tall
Tell him to say sorry
Run him over in a bike or land speeder
Ice Cold in Alex
The Sound of Music
A vehicle garage
A nice house just outside London
