Also known as: 大豊娘娘
A fan made character who represents (personifies), plays the role of a Mascot, or a Booth Babe for the fictional company 'Dafeng Core Industry' from the game Armored Core VI: Fires of Rubicon.
The name Dafeng Nyan-nyan derives from the company name 大丰 'Dafeng' and 娘娘 'Nyan-nyan' (pinyin: Niang-niang), the latter means 'Lady' or 'Highness' in Chinese, as Dafeng is a Chinese themed company.
As originally conceptualized by Twitter user Tohuyasan, the design of the character is based on the in-game company's design philosophy: "Stout tree, Slender branches", which is interpreted by artists as large/Huge Breasts Thick Thighs, with slender limbs.
The two Hanzi character used for the company name Dafeng can be literally translated/interpreted as big and bountiful, which may have also played a role in defining the character design of Dafeng Nyan-nyan.
