Called Effy, this great sculpt by Elyssa Ketchersid was created using ZBrush, Maya, Blender, Substance 3D Painter, and Marmoset Toolbag.
The character is a 3D interpretation of a design by Sergi Brosa, Senior and Principal Concept Artist at Gearbox Software, which explains the familiar aesthetic. Effy is part of his original sci-fi character series, Fury Beats. Check out more 3D renders of Effy below and on ArtStation, along with the 2D concept:
