His name is Eternity’s Embrace and he was once a powerful unicorn wizard who tried to find the spell for eternal life, ended up blowing himself up when he tried and irony dictated he became part immortal robot as a result. What a twist.

He put all his faith in magic to give himself eternal life, and when it blew up literally in his face, he stopped trusting in magic and gave all faith to science instead. He's a sad, angry little man (pony).

He patented a technology to give non-pegasi wings through the use of aether matter.

Here's what his his magic looks like.
