Ok first: they need a Human category in the submission manager, so we don't keep having to put "other".

Secondly:

This is Jack, he is a trigger-happy cousin to everyone's favorite: "Steve?" (yes his name is Steve? with a question mark, look on the Minecraft Wiki).

He is approximately 28 years of age, having successfully campaigning in the following wars in chronological order:
The End War
Creep War I
The Chunk War
The Taiga Skirmish (really lasted a decade, blame BertieChap)
Golem War IV
Creep War II
The Nether War (also called Herobrine's Most Recent Assault)

As you can imagine, after 15 years of battle, he has become a little, ehh, "twitchy" when it comes to certain sounds or sights.
In other words, he has developed severe Post Traumatic Stress related to explosions and Creepers.

Always ever present, his trusty iron shovel is ready to assist him in bashing in some poor creeper's face. (Please note; Jack doesn't really mean this, he's just stuck in his Warzone flashbacks anytime he sees or even hears the word "Creeper")

I hope you like this skin, as it is the in-game version of Jack from my AMA blog on tumblr.
Go ahead and ask any of these guys whatever you wish. I also mostly made this for the blog's official map (set in the latest snapshots of course)

A helmeted version is possible if I still have ambition left and don't get sidetracked with another drawing or Minecraft.
