Mega Darts (also known as Sucker Darts) were at one time the most popular Nerfammunition, until they were entirely replaced by Micro Darts. Mega Darts are larger and more powerful than Micro Darts, but they have lesser reach.
Their popularity began to decline as more and more people began to purchase Micro Dart-compatible Nerf blasters. They were made of less dense foam than the current darts. A few variations were introduced of this type of dart, especially the Screamin' Mega Dart, which had a whistling head.
