This is an LDD version of a jetsuit and laser cannon for minifigs that I came up with many years ago. I couldn't really call this a jetpack because he doesn't really wear it. He fits into it. It's more like a vehicle. The jetsuit is equipped with 4 primary and 4 directional thrusters. The two center thrusters are on hinges for even more aerial acrobatics. It has a heads up display that hangs just above his head. It's armed with 4 forward firing lasers, 2 sonic emitters, and 2 rear firing laser pulse grenades. The oversized laser cannon has both a laser and a pulse grenade launcher.
