Liberty Prime vs. Metal Gear REX
Liberty Prime from Fallout 3 fights REX from Metal Gear Solid. Apparently, Prime was stolen from the Pentagon and sent to Shadow Moses but at the same time, Liquid thinks REX would look good in communist red. Liberty Prime is put in the same hanger with REX and when accidentally activated, it sees Metal Gear REX as an enemy. Noticing that Prime is about to attack, REX is now also prepared to attack.
