Can you edit the blue guy in the template in other software?

Can you use that blue guy in the template (fps) in zbrush to bring details and textures in it or do I need to make a character from scratch?
If you could edit that blue character, can you also use it in maya as well for new animations?

Yes, you can use it in 3d programs → just do a right click onto him → export → fbx → save

Ok thanks!
