Big Sisters are Rapture's fiercest predators. Despite being covered in armor they possess deadly agility and can strike from anywhere. Charged with protecting Little Sisters, Big Sisters keep an eye on all of the ADAM in Rapture and punish anyone that disrupts the balance. Able to throw objects telekinetic-ally, leap off walls for powerful melee blows, throw fireballs, execute devastating charge attacks and even extract ADAM directly from living Splicers, Big Sisters are the worst nightmare of anyone unlucky enough to draw their ire.
Big Sister is of similarly massive 7"-plus proportion and detail. She has a removable backpack with a cage basket just the right size for capturing a Little Sister and ball joints at the neck, shoulders, elbows, wrists, hips, knees ankles and ab crunch.
