Delta Subject (Bioshock 2).

Subject Delta (symbol: Δ and known as the First Big Daddy or the Prototype Big Daddy). Delta was the first Big Daddy in the Alpha Series successfully bonded to a Little Sister. He has a delta symbol on his suit, which is the fourth letter of the Greek alphabet, signifying that Delta was the fourth counted test subject taken from Persephone for the Fontain Futuristics Alpha Series conversion.
For this figure I decided to add an "extra" by sculpting a micro figure of a Little Sister following the concept of the micro AI's in the Halo figures.
