Crimson fog


 * ''The "crimson fog" is an unnamed weapon in the Beast Wars portion of the Generation 1 continuity family]]

Megatron's "crimson fog" is a transmitter, possibly a variant of the Predacon shell program that causes a gradual buildup of irritation in Transformers that magnifies disharmony, eventually resulting in in hostile behavior up to and including attempted murder.

The weapon is launched as a parachute-arrested gravity package from a floating platform, and can be programmed to home in on a transmitter during the descent.


 * ''The weapon is not named. Megatron's internal monologue refers to it by the flowery term "crimson fog."

Fiction
Megatron sends Quickstrike (then awaiting trial) to plant the "crimson fog" in a strategic location near the Ark, hoping the Maximals will destroy one another. Though initially successful, the experience of beating on his fellow Maximals awakens recent unpleasant memories for Optimus Primal, who is able to break free of its control.
