In Bloons Monkey City, it is a permanent upgrade that replaces the Temple of the Monkey God when the player acquires a Special Item called the Dark Temple Idol. In BTD5 Mobile and BMC Mobile, it is an ability that can be activated for ten seconds each time. It also shoots two beams at a time instead of one. This tower can utterly destroy anything if affected by MIB Call to Arms and Overclock at the same time.
