Uzzah defiled the Ark by touching it with unclean hands, and died. One of the Bible's most prominent heroes (David) was very upset with God for that reason. I would say Uzzah belongs on your other thread.
The Ark of the Covenant was captured by the Philistines. If you haven't read the story, you should read it. It caused a plague to spread throughout the land, and it got so bad that they literally brought it back. So when the Ark is active, even if the EC wins, he dies.
12-Fingered Giant probably fits well into the category of "we wanted someone to negate big FBTNB chains." Not much is known of him, except that he was a giant with six-fingers on each hand, and six toes on each foot, he was killed by Jonathan (not the prince, the 6/6 purple guy from Unlimited) and he taunted Israel.
The ones I can think of that don't fit well are:
Authority of Christ--Jesus never killed anyone, and the story talks about his authority over the weather.
The Garden Tomb--Obviously the characters were chosen for a Biblical reason, but the SA was merely chosen to combat splash defenses.
We all know how that worked out...
