The mighty Leviathan carries in its sacks of Vestibuls, the makings of the ultimate swarm. If left unchecked, the Leviathan can turn the tide of the battle almost instantly for its team. Besides its ability to create mass armies of zerg ready to do your bidding, it carries with it some of the most powerful debuffs that no other Ship Commander possess. Not even the might of the Mothership can withstand its Microbial Infestation. Not even the Shield of the Viper can protect itself against its Bio-Plasmic Discharge. Yet with all its power, its low armor and lack of escape mechanism makes it squishy prey for ganks and those with AOE attacks.
