Yeah, skin color changed with wookieepedia description, perhaps it was when Wizards bought the licensing and did their normal "Let's F**k with everything" thing. The original in WEG 2nd Ed RPG was described as black, cover in scales of keratin, though the drawing wasn't as good. No mention of other colors and my personal preference is black so I'm going with that.
Hands will be 4 fingers and thumb, maybe gloved, may try some kind of covering...we'll see. Also need a tail. Feet are normal enough for boots. Height is listed as 1.9-2.2 meters tall (roughly 6'2" to 7'2". They are strong as a wookiee and very resistant to damage from both physical and energy weapons. They could probably qualify for medium armor naked. lol. My barabel RPG character was a tank and very difficult to even slow down, stopping him really never happened and that was without running rampant over game balance. They are just really tough critters.
One of the toughest parts will be making a bucket that will fit over the mask. It'll have to be a scratch build as even an HBF mod will be too small. It'll be like wearing 2 helms, so his bucket will only be for some photo ops.
His weapons will be the same I use now, pair of SE-14r's and a T-21, very similar to what he had in my RPG.
