Organic explosive
Organic explosives were explosive devices used by Triannons embedded within their bodies. It was activated by them inserting a metal pin in a form of a brooch into their arms.

In November of 2153, a number of Triannons came aboard  in the Delphic Expanse after sending out a distress call. A Triannon religious zealot named Pri'Nam D'Jamat took control of the ship in order to destroy an opposing faction he deemed heretics by having his people with the organic explosives surround the ship in vital areas, including the warp core. Captain Jonathan Archer was able to regain control of Enterprise thanks to Doctor Phlox creating an airborne agent which neutralized the explosives. ()
