Splitter

Splitter are a variant strain of the baneling that appears in Heart of the Swarm.

Overview
During Kerrigan's resurgence, Abathur discovered the Splitter strain in a feral Mitoscarab. After acquiring the essence of the Mitoscarab, the Splitter was formed. The unique decentralized nervous system of the Mitoscarab was emulated by the Splitter. Upon death the Splitter would split into two smaller Baneling Spawns. However this process can only occur once, further splitting will result in acidic fluid of limited sentience.
