I have been thinking about rules on how to add an avatar of yourself into 40K. Usually a gamer is represented by the HQ unit on the board, but what happens when your HQ is a named character? I am using Vulkan He'stan as my HQ, and sadly I'm a poor substitute for Vulkan. I decided to make an avatar of myself using some spare bits, and some special order bits from MaxMini, Anvil Industry, and Forgeworld. I am running an Ultramarines army, and I wanted to keep with the Roman style that is seen in the Ultramarines miniature range.
I decided to make my avatar a gladiator with two swords. His helmet had to be easily identifiable as a myrmillo. I wanted to get an over armored right arm, and an under armored left arm, but I wasn't able to find anything like that online, so I just got different shoulder pads instead. Looking back I should have looked at the Dark Eldar range. I also needed a range weapon for him, so I made sure to use the gauntlet bolter of the Blood Angels Sanguinary Guard. Once I had all my parts together, I started assembly. I reposed the miniature using some metal pins, and green stuff. The base is made of cork, dipped in sand.
As far as rules are concerned, I was thinking of having my avatar being worth 1 victory point. The point is earned if he is captured, not killed. You capture him using the Relic rules. The catch is he can only be capture if his squad is destroyed, and he is killed (knocked unconscious). I would only use the avatar house rule if my opponent also had an avatar, this way the possible points earned in a game will not suffer.
I was also think of making a vehicle pilot avatar. A vehicle would be worth 5 victory points. To earn the point you will first have to destroy the vehicle. An objective marker would be placed where the vehicle was destroyed. Then you use the objective rules to capture the downed pilot.
