The splitter is a variant strain of the baneling that appears in StarCraft II: Heart of the Swarm.[1]

Game UnitEdit

Splitter SC2-HotS Game1

The splitter

The splitter has a very minor aesthetic difference from the regular baneling, simply letting out a light green smoke from its abdomen.

The splitter splits into two smaller baneling spawns upon detonation, each baneling spawn does 5 damage/10 to structures and has 20hp and the same armor as the baneling.

In comparison to the hunter strain, the splitter strain has greater overall damage potential due to the baneling spawns, which add more damage output per baneling. Though they lack the closing ability of the hunter strain, this can be compensated via Kerrigan's Spawn Banelings ability, placing the splitters right in the middle of an enemy formation.

Heart of the SwarmEdit

The spawn of the splitter

It becomes available with the hunter after completing "Old Soldiers."[2]

During Kerrigan's resurgence, Abathur discovered the splitter strain in a number of mitoscarabs of the planet Nelyth. 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, as further splitting will result in acidic fluid of limited sentience.[2]

Co-op MissionsEdit

Zagara's banelings automatically upgrade to the splitter strain when she reaches Level 14.
