Crawler

The Splicer model "Crawler" is specific to Spider Splicers in BioShock 2. As was the case with the Spider Splicers in the first game, this model shows the most physical deformities of any Splicer in Rapture. They also appear in Minerva's Den as scientists, mostly wearing glasses with their suit variation.

Appearance
Crawler is the most inhuman-looking Splicer in not only BioShock 2, but of both games. He has a bald, misshapen head, a bulging eye, long bony limbs, claw-like fingers, and four toes. His teeth are small and pointy, and spaced far apart in his gums. His clothes are tattered and worn-down, especially at the ends of the sleeves and shorts, likely due to the act of crawling across many surfaces. His physical behavior seems more animalistic as he hunches over when walking and crawl about on all fours at times, thus the nickname Crawler.

Personality
Crawler seems to suffer more, both mentally and physically, than any other type of Splicer. He suffers from insomnia, delusions and many other problems, probably caused by splicing. Because of this, it seems he has sought a myriad of treatments from Sofia Lamb, as he talks about many of them including the more dangerous Electroshock therapy. It could be inferred that he had to undergo hypnotism with her as well; he speaks normally and calmly while under the Hypnotize Plasmid as if talking to her, and he will also follow instructions that Delta hasn’t given them, implying that he’s been given the same instructions previously. Judging by some of his quotes, Crawler thinks that Delta and other enemies are responsible for the voices inside of his head, and that killing them is the only effective means of putting an end to the torture.

Behind the Scenes

 * At the September 2011 Sac Anime convetion, Yuri Lowenthal mentioned that the developers of BioShock 2 originally intended for the Crawler to have an Appalachian accent, but that direction didn't seem to work, and it took a good four hours of looking over the concept art and revising his voice until he developed a good sense of the character being more insane.
