The Ootheca is large AC-sized missile that therefore cannot be launched by any normal-sized mech, including ACs. It is seen to be launched by the Argus and Stork, out of specially built holders. Multiple launchers can be loaded onto Argus Train cars. The Ootheca does not deal damage directly, indeed many of the times it is encountered it has already impacted the ground. Instead, it launches massive volleys of snake-like blue missiles that home in on their targets, leaving behind zigzagging blue streams.
