It had to happen eventually, what with all the other Halo art I've seen. I finaly took the plunge and drew my Wolf Character Lohfrum in MJOLNER armor, slightly modified to fit his form. When I came to his tail, I was stumped. I wanted his tail to be protected, but I wanted the protection to look like it was part of the original suit. All of a sudden I came up with the segmented armor and bladed sections. This way, not only is his tail protected, he can also use it as a melee weapon, keeping his hand free for weapon use.
As for the name: I figureed that he was obviously the squad leader, and he IS a wolf after all......hence Alpha Chief.
