White Splicer

From BioShock Wiki

This splicer model is painted or coated white. They are disguised as Cohen's plaster coated human statues.

These splicers can be creepy as they attack in silence, unlike the other splicers, which scream and talk to themselves constantly.

They are activated by using the Power to the People machine in the basment of Sinclair Spirits in Fort Frolic. Right after using the machine, a White Splicer spawns behind you. Apparently, due to its disappearance, it was the one in the chair by the stairwell. Nearly all the White Splicers found in the level will come to life (they actually just disappear), and they will then spawn constantly throughout the level.

Though they're any not more dangerous then any other Spider Splicers in theory, they are completely silent, love to come out of the shadows, and often appear almost out of nowhere, making them very frightening at times.
