Hey! Forgeworld released a kit of legs for that thing! I think it stood taller than an Imperial Knight, and looks GREAT. I'd love to see it in EC.

So much better as a Nurgle daemon engine.

All of them if possible! Starting with the Defiler, Forgefiend and Maulerfiend. When aircraft are included, Heldrake. Superheavy ones would have to wait for the appropiate expansion.

At the same time, Chaos Vehicles could unlock Daemonic Possession. On the TT, it reduces their aiming skills but makes them inmune to Crew Shaken/Crew Stunned: maybe this could translate on better traction and control under heavy fire. Or just have it as a cosmetic upgrade.

I like the bell above the head, reminds me of christmas time. (still, these are not legs, just imitations covering the tracks)

Years later when we have Titans, i'd love to see a Subjugator of Slaanesh and a Quester.

Forgefiends! Forgefiends!
Or Defilers, they're both pretty sick. I'd like to see a Helbrute, for the fun of it.

As Maky said. This.

Plague Hulks.
Blight Drones.
Defilers.
Blood Slaughterers.
Brass Scorpions.
Decimators.

Thanks for posting the image!

Oh yes, forgot about those!
