10 Deadliest Comic Book Events

10. Civil War

Civil War may be one of Marvel's most loved storylines, but it came with a heavy toll. Let's face it, any story that starts with the death of 600+ people is pretty unlikely to back off on the causalities as the fight hots up.

The story starts when The New Warriors are trying to take down a group of villains. Unfortunately for them, they were woefully unprepared. Things go well at first and the group manage to get the upper hand, but in one moment everything changed.

Nitro, determined not to be taken down by some D-list heroes, unleashes his full power and causes an explosion that takes out an entire neighbourhood.

The resulting story has been told hundreds of times and features some of the most tragic superhero deaths we have ever seen. While the death of Captain America and Bill Foster took the headlines, the fight to prevent further collateral damage may have caused even more than the original incident.

Take into account the various government and S.H.I.E.L.D agents who lost their lives while part of the "Cape Killer" squadron, plus prisoners taken out when Speedball regained his powers, plus the fact The Punisher was involved... The list just grows and grows.
