Supercharger, or "Bongo," can move a team fight just by existing. However, killing it is easier than a Symmetra teleporter. That being said, protect Bongo by planning out its placement. If you're holding a choke, place it directly behind the corner so the enemy team can't destroy it. If you're in the open, throw a shield directly in front of it. Once that breaks, body block it with Fortify.
