The Roachester using BugKamikaze on Harle.
BugKamikaze (小虫特攻 , Ko mushi tokkō, lit. Kamikaze of the Small Bugs?) is a Blue Enemy Tech used by the Roachester in Chrono Cross. This tech grants allows the Roachester to sacrifice its babies to inflict fairly heavy damage onto a single target in battle.
The camera will shift its focus to the Roachester's back, whereupon little white bugs are observed to flutter off. They then gather together, and proceed to, one by one, hurl themselves at the target, causing an explosion of blue light to knock said target onto the ground, sustaining damage.
The Kamikaze refers to suicide attacks made by military aviators from the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, designed to destroy as many warships as possible. Kamikaze pilots would attempt to crash their aircraft into enemy ships in what was called a "Body Attack" in planes often laden with explosives, bombs, torpedoes and full fuel tanks. (Information taken from Wikipedia.) In this case, the Roachester sacrifices its offspring in a desperate bid to kill its foes, and hence, the name of this tech is a befitting one.
