I'm afraid many will turn up their noses, anyway...
In the fifth edition Space Marines codex there are some options to make quite competitive army lists: I found that Vulkan of the Salamanders is the most funny and suitable to my way of playing so, since there are no restrictions about the use of special characters in other chapters different from their own, I chose to make Vulkan join my Ultramarines army.
I don't like at all the GW miniature of this Salamanders' hero and even if I liked it I wouldn't buy it because I didn't want to use a Salamander with my Ultramarines, even if it is possible to do that.
So I chose to make a conversion. His name is captain Cassius, my historic Ultramarine commander.
I started from an old metal Space Marine body (precisely mark 7 armour 6, from 1990 range) and then i added stuff in order to reflect Vulkan wargear. After all I like to stick to WYSIWYG rule. I think that this body has lots of personality, seemslike he's looking for enemies to slain.
The Spear of Vulkan, which is a master crafted Relic Blade, became a two handed sword taken from Grey Knights bits. GK weapons are amazing stuff, before them there were no two handed weapons for Space Marines, except some previously released metal stuff.
Gauntlet of the Forge is sort of heavy flamer built in an armour gauntlet so I converted it starting from GK forearm storm bolter. Quite easy.
Kesare's Mantle has been represented with the old Space Marine commander metal cloak. This is going to be painted in some fancy way.
Artificier armour is yet to be represented (as well as Digital Weapons). I'm thinking about some milliput sculpts.
I added some detail in order to show his "veteran" status like a Crux Terminator and some Purity Seals. I also used Space Marine captain sculpted shoulder pads and a Ultramarines banner icon.
What do you think? If you have any suggestion please let me know!
UPDATE: I just saw GW miniature. In comparison mine looks silly! I've got to load my version with more detail so I hope to post it back soon!
