C.L.A.S.H. is a comic book series published in France but realized by Italian artists Franco Frescura and Giorgio Trevisan for Editions Lug in 1969.
Headquartered in Aspen, Colorado, C.L.A.S.H. (the acronym stands for Consortium for Law-Enforcement Action for the Security of Humanity) hides behind the cover of a multinational insurance company, but in reality is a United Nations organization devoted to fighting threats to global peace, in particular from a worldwide criminal organization known as CRIMEN. Its weaponry includes the "Leviathan" (a flying fortress), Samael (an orbital space station), a fleet of ICBMs, and "paverine", a highly-potent psychotropic with extrasensory applications.
C.L.A.S.H.'s Director is William "Billy" Brown, who reports directly to the U.N.'s Secretary-General. Its top agents are Kazuhiko Song, a.k.a. "Mister Song", Sara Kissinger, a.k.a. "Miss Kiss", trainee Joanni Bourask, head of Psi Division Dr. Jesse Malone, and chief scientist Dr. Kalamazoo.
Originally entitled "Mister Song", the adventures of C.L.A.S.H. were originally published as a back-up feature in the six, digest-sized issues of Wampus magazine.
C.L.A.S.H. returned in 2001 as a supporting element in new adventures of Wampus, Homicron, Kit Kappa and the Strangers. It was eventually revealed that C.L.A.S.H. had been created in 1947 by the then-U.N. Secretary-General Trygve Lie of Norway, with the active support of U.S. President Harry S. Truman at the behest of the mysterious Tanka.
C.L.A.S.H. is now part of Hexagon Comics which has published a collection of its adventures translated into English.
