Diamondhead is an Alien Force character that is making, or has made a big impact on the animated series Ben 10. He is a emerald green being that comes from the planet Petropia. I remember specifically when Ben first used Diamondhead, it was so cool. He needed to use an alien that could take on Vilgax's giant robot. It was episode “And Then There Were 10”. Remember when I said that his color was the color of an emerald? That's because his body is made from an unbelievably durable crystal that is both organic, and makes him almost invulnerable to anything. What's cool about Diamondhead is his ability to omit crystal like weapons from any part of his body at will. If an enemy where to use a laser of some sorts on him, it would be completely useless because since his body is like a jewel, things of that nature will just reflect right of him and bounce back to the one that triggered the weapon. Like all glass or jewel like objects, if they shatter, they break right? Well with Diamondhead, it's the same thing. His body can shatter if exposed to a very strong sonic vibration. I know this seems fine because aliens of his race can regenerate limbs, but the problem with that theory is, if the damage is significant enough, there is no recovery. His color reminds me of kryptonite from the Superman stories. I think this is going to be a very popular lesson because when you learn “how to draw Diamondhead", you will also be teaching yourself the skill to drawing Ben 10 aliens as well. Have fun guys, and expect to see more tutorials on the way today. Peace out!
