Lehvak

Lehvak work in swarms, though they tend to operate best in smaller groups, hitting and running, and thus they are probably the most individually motivated of all the Bohrok, and more than capable of thinking and operating alone. The Lehvak are clever tacticians. They never strike in one place for long and it is hard to predict where they will turn up next. The only real way to stop them is to corner a group and surprise each one individually. Lehvak are the most dangerous of Bohrok because of their powerful acid, which can dissolve any substance. When they attacked Le-Koro, they replaced all but two of the Le-Matoran masks with Krana. The Le-Matoran then overpowered Toa Lewa.
