Big Sisters

The Big Sisters are post-pubescent Little Sisters that have become unstable in Rapture's environment. Ten years after the events of BioShock, they are charged with maintaining the ecological balance in Rapture. Their extreme level of powers, far beyond normal Plasmid users, can be attributed to their bodies adapting the ADAM created in their bodies as children while they were still developing. Thus they have a much more natural affinity for the powers that ADAM creates.

The Big Sisters wear diving suits reminiscent of those of the Big Daddies, but their suits have a distinct aesthetic since each is assembled from scavenged items rather than manufactured. These suits were designed by Gilbert Alexander, as heard in an Audio Diary. A Big Sister helmet consists of a large sphere with two portholes. Despite their limited amount of armor, Big Sisters can withstand the pressure required to venture out of Rapture and into the ocean. Big Sisters are formidable beings that are known for their agility and Plasmid prowess. They wield large, wrist-mounted needles on their left arms, which are used primarily for melee attacks and extracting ADAM in a manner similar to a Little Sister's extracting needle and allows the Big Sister to regenerate health in combat from Splicers. Big Sisters are the only creatures in Rapture known to be able to damage the exterior glass windows of the city, something that shooting bullets, grenades, a drill or any other weapon have failed to do.

The Big Sisters' designs are geared towards accommodating Little Sisters; they have a cage-like basket that is adorned with ribbons, which is used to safely carry Little Sisters on their backs, and childish doodles can be seen on their oxygen tanks.

Attacks

Big Sisters have been observed to perform six different attacks:

Stab: A Big Sister's basic attack. When at melee range, she will jab her ADAM syringe into the player, dealing a high amount of damage.
Charge: When at a distance from the player, a Big Sister will run towards Delta at a high speed, dealing minor damage and minor knockback, as well as temporarily disorienting the player.
Fire Barrage: Occasionally, a Big Sister will fire three large exploding fireballs in quick succession, dealing high damage.
Telekinetic Pummel: Occasionally, a Big Sister will use an advanced form of Telekinesis to lift every nearby object around them, pull them towards her and fire them at the player, with the amount of damage depending on the size of the object. If the object is large enough, it will push the player back, temporarily disorienting them.
Drain: When low on health, Big Sisters will run towards a wandering Splicer, impale them with their ADAM syringe and drain their health. This gradually recharges the Big Sister's health, but leaves her vulnerable. Attacking her while she is draining a Splicer will cause her to drop her victim, killing the latter in the process.
Teleport: Big Sisters possess a unique version of the Teleportation Plasmid used by Houdini Splicers. The energy ripple seen when they disappear is purple as opposed to red, and they can teleport much farther. They are seen using this ability in a handful of scripted situations throughout the game, and they may also use it to reach the player from a distance during battle.
