As early playtesting went on using my Sin Eaters (way back in 1999) it looked like getting a second Dreadnought on the table would be fun. While Brother Rhinox was made more or less exclusively from the basic metal chaos Dreadnought kit, Tankorr was made from a metal Imperial Dreadnought, albeit an Imperial Dreadnought with loads of spiky death metal type junk stuck on. Examples above include the spiky panels on the main housing and the tombstone-for-a-face.
Tankorrs arms were made from spares from the kit that was used to make Rhinox. The left arm above had an Ork Choppa and two Necromunda Pit Slave weapon arms attached. I also added another pit slave chainsaw bit to the front of the body on that side for good measure.
In the above shot you can make out bits where some of the many spikes attached to the figure used to be attached, only to have broken off at various points over the years. The lesson here is simply not to bother sticking those things on in the first place. If Tankorr gets away with it it is simply because of the zombie-like, dilapidated look.
I like the combi-bolter mounted on Tankorrs shoulder for some reason that I cant put my finger on. I also like the silly zombie hands bursting out of the ground, “Thriller” style.
