not weird. Its bioshock

Welcome to Rapture home of the splicers.

So I have to fill you guys in to understand this being.
This is the bouncer big daddy.
Big daddy's are bonded to little sisters and will react aggressively to anything that stands between them.
The Big daddy Dwells in the underwater city known as Rapture this city used to be tranquil until the discovery of a sea slug which a chemical known as Adam can be harvested. This chemical causes instant mutation which creates splicers beings who are addicted to Adam. The little sisters are designed to harvest Adam from dead splicers. as the splicers abused more and more Adam they became more dangerous and hostile. This meant the little sister needed a bodyguard. scientists gained convicts or the criminally insane and were fused into the suit and buffed up. These people became bodyguards and bonded with little sister to protect them. This is not the first model of Big daddy.

If the big daddy has no little sister he will wonder aimlessly trying to find them.
