Abathur is a unique zerg creature, created from numerous zerg species. He is the zerg evolution master, serving as the Swarm’s DNA library, and resides in the evolution pit.
Abathur was created by the Overmind as a “brood of one”, spun from many species. While it was the Overmind that was the will of the zerg’s drive to perfect, it was Abathur who was the instrument of its will.
By the Overmind’s instruction he designed the Queen of Blades by wrapping her in a chrysalis, though not without injuring her in the process.
Abathur is well-mannered and is constantly connecting DNA, experimenting on strains and studying the Swarm’s enemies. He does this by eating (parts of) creatures and gaining access to their genetic code. It is a process that he enjoys—even though protoss essence is incompatible with the zerg, that doesn’t stop him from trying anyway. Exactly how Abathur manipulates genetic codes isn’t fully understood by Dominion scientists. They have suspect that the central intelligence (Abathur himself) behind these manipulations must exhibit nearly quantum-level “big-data” processing abilities, far beyond terran capabilities.
He dislikes being in space for extended periods due to the lack of bio-matter.
Abathur accepts that true perfection is impossible for the zerg to achieve. However, it makes sense on the tactical level for him for the zerg to continue chasing perfection regardless. He also believes it is “purpose” which makes the zerg what they are. He states that without an overriding will, they are no more than beasts, much like he was after the death of the Overmind. To this end, he is grateful that the Swarm has a purpose, even if it is to fulfill Kerrigan’s vendetta. As much as a hive creature can, Abathur sees himself as being personally responsible for the continuation of the zerg. He undertakes each experiment as though the survival of the species depends on it alone, and tolerates no evolutionary backstep.
Abathur is unimpressed with terran essence and DNA, along with their “primitive structures” and minimal biological adaptability. He considers them to be a doomed species due to their lack of genetic diversity and proliferation of recessive traits in their gene pool, and was glad when Kerrigan stated that they’d no longer experiment on them. Similarly, he holds the primal zerg in low regard, noting that though some displayed favorable traits, they were sloppy and inefficient. He thought even less of them when he discovered they quickly replicated some strains from the Swarm, prompting him to implore Kerrigan to wipe them all out. An amused Kerrigan noted that Abathur sounded upset, indicating he may hold some level of pride or possessiveness towards his “work.” Despite his view on terrans he is fascinated by Alexei Stukov, whose modifications are on a level Abathur himself is unable to achieve, and considers Stukov second only to Kerrigan.
Abathur seems to be obsessed with efficiency. His goal is not to make the zerg perfect, since perfection is impossible; instead, he tries to make them as efficient as possible. Outside of that, he points out to Kerrigan that killing a creature before consuming its biomass, while it would be less painful for the creature, is inefficient, since the creature’s death is imminent. He considers himself to be the most useful part of the Swarm.
Abathur has an odd speech pattern, often leaving out conjoining words and ignoring pronouns. In a way, he speaks in the most efficient manner possible, befitting his approach towards genetics.
