This is a heavily modified model of Eevee originally from Pokemon X/Y/OR/AS that I worked on (This isn't the same model from the other Eevee test animation earlier this year). Most of the modifications are to the face, as well as the textures. Though it normally wouldn't matter to have a much more detailed face to do a walk cycle test animation, you'll still get to see it get shown off a bit in the last 5 seconds.

This model was modified, rigged, and animated in Blender. Rendered in combination of Blender Cycles and Blender Render.
