This is Negative Pulse. He is the last living Droid Pony. He has a heart of steel that would take a very very special somepony to soften even a little. He seems to never smile and this is because of the battle bettween Celestia and the Droid Ponys. He never goes anywere near pony villiges or cities but loves animals and cares for them. He is 18 years old and is soon approcing his b-day.
