Freom (Mk.II) from Spark the Electric Jester (1)!
His head is way to spiky to properly translate into Minecraft, but I tried my best!

Freom, also known as Unit 1, was originally a guardian robot, his purpose was to protect Clarity, a powerful AI that would eventually take over the world. Despite her goal, over time he found himself falling in love with the AI. Eventually she was able to build a body, and that's when their love truly bloomed. Eventually, Clarity's goal would be discovered by the formies. and she would be destroyed. Freom found himself now lonely, until one day when she sparked back to life on a monitor screen. He was happy, but he could tell that something was a little off about her now, so he build a "son" in the form of Unit 2. Unit 2 would be born with no memory of what he is, so that he would one day find his own destiny. Freom's goal with building Unit 1, later known as Fark, was hoping that Fark would one day destroy him and defeat Clarity.

Spark and his games were made by LakeFepard and are available through Steam. They are the best 3D Platformers I've ever played, and you should check them out!
