Looks really cool, can't wait to see it move and in action.
How I imagine his introduction after the animations are done:
same scene as in the video in the update
- music plays, the camera pans around him showing details etc.
- a close up on his face (the music fades a little bit), it lights up with LEDs and turns his head towards the camera
- a deep male robotic voice says "ready for action boss"
- then the camera pans out showing how his entire body turns towards the camera
- he raises his drill arm a little bit and starts to spin it
end of scene
after that the full demo of him in action can be shown - somewhere in a landscape, drilling, fighting some mobs etc.
