- Fire-retardant foam is a substance from the cartoon portion of the Generation One continuity family.
Fire-retardant foam is a foam used to retard fires. It is also among the mightiest weapons known to Transformerkind.
When the Autobots were disabled by a Decepticon sneak attack, Spike prompted the Autobot computer Teletraan I to release fire-retardant foam. The foam landed on the Decepticons and immediately shorted out their circuitry. Recognizing this unbeatable foe, Megatron ordered an immediate retreat.
The Autobot Ironhide was also capable of releasing the substance, among other compounds, from a nozzle embedded in his wrist. That guy could shoot just about anything. Why he never used its almighty power to annihilate the Decepticons once and for all is not known.
Even across the generations, the legendary power of fire-retardant foam may be slightly diminished, but it is still to be feared and respected. The current incarnation of Optimus Prime still makes use of it as one of his weapons, and it has proven capable of debilitating even a mighty Decepticon or two. It has knocked out Starscream's jets in mid-flight and rendered Blackarachnia incapable of moving for several seconds while she cleared it out of her eyes.
