Fortunately I had the GW river troll set that came with 3 trolls.
At first I thought I would only use two of them, but then realised that I wanted to paint the Orc team troll in the team colours. I was also pretty sure that my Goblin team would have different team colours, which meant if I used the orc troll in the goblin team it wouldn't have the same team colours.
I could paint the troll in a neutral scheme, but since I had 3 trolls I decided to use all 3, one for the Orcs and two for the Goblins.
I will come back to the Goblin Trolls at a later date. After the Tigerz are completed.
I started by thinking how I wanted the troll to look. One idea I had was that the troll was imitating a troll slayer. I would give it a mohawk and fake beard. But I also wanted the troll to have armour to fit in with the rest of the look of the team, which didn't fit with the troll slayer idea. In the end I put the troll trollslayer idea to one side.
I found the river troll set from GW to be really good. Lots of parts to play with and good value for money. I understand it is no longer being made due to it not being AoS, so will be hard to find now.
I had brought a number of armour parts and bits from Bitzbox, a site that sells parts of sprues and bits of model sets. For the troll I had purchased an imperial guard orgyn breast plate and bits from an an Ork Deff Dread.
The Troll was given two fists with one raised above his head ready to smash down on anything in front of it. I had to cut a weapon away from one of the hands/fists. The breast plate was added on. It was the right size to cover the front of the troll and also the right shape, in that it looks a poor fit, which I think is in character for the model. I may try to add my own straps to it later.
While I didn't plan to at the start I ended up having the troll having armour only on it's left side. I quite like how that has turned out. I just wanted to find something for it's left leg/knee I will be happy with leaving it at that.
Looking through the sprues I had, the Stormboyz had rocket packs where the top cone of the rockets looked like knee pads to me. See below.
I cut away the pins from the inside that would have been used to attach it to the other half of the cone so I could glue to the troll's left knee.
Pictures below of the Troll.
I am happy with how it has turned out. It needs some minor cleaning up/ cutting away of excess plastic. The only other thing that I would have liked to do is add some strapping to the armour and pads, but not sure how to go about that. At the moment it means some fine detail work with putty and I would rather find a cheat, then attempt to model in putty.
