Mr. Incredible attempting to stop the train from falling off the track.
During the glory days of Supers, Bomb Voyage, during a bank robbery at night, sticks a bomb on Incrediboy's cape. Mr. Incredible attempts to take the bomb off his cape, but he and the bomb fall onto a train bridge, destroying the bridge. Mr. Incredible tries to stop the train from falling off the track, but he could only stop it after the front carriage teetered over the ground below. Dozens of passengers were injured as a result of the accident.
Mr. Incredible was later sued by the injured passengers, costing the government millions. Combined with public outcry, the government was forced to ban Supers permanently.
