If you've ever seen an old-fashioned locomotive, you've seen a cow catcher before. In real life, cow catchers are usually attached to steam trains. These large metal structures at the front of the trains are generally used to deflect any debris or detritus that happens to end up stuck along the track while the train is in motion.

As far as Fortnite goes, yes, cow catchers essentially serve the same function that they do on actual trains. However, we here at Distractify do not endorse the use of cow catchers to deal heavy damage to your opponents in real life.
