I think we should be ironic, since we're chaos. Make a suit similar to Tiberius', but smaller, lighter, and no flamethrower. Put wood in again, give it life, and imbue with chaos. Laskarus was a servant of a god of death, so what's more ironic than a suit of life and chaos? Chaos makes it faster, I hope, more agile, but no flamethrower. Instead, thorny vine-like things somewhat like Tiberius, but able to wrap around and pull, while on the other hand? A Needler. Think of an organic machinegun that fires large barbed thorns or quills. Life includes animals after all. Once Azula comes back, of course.
Seeds of Manna are a good idea, I think. And we could ask the souls in the afterlife whether or not they'd like to be 'alive' again. If they are, two trees can be imbued with their souls, given mobility, a few Needler, some Lasher Vines(the pulling vines), lots of Thorn Armor(big hard thorns), and some Dragon Maws(flamethrowers). Four 'legs', and eyes. Eyes could also function as a mouth, in that the sound for their speech comes from it. Turn any copper not used for temple into custom armor. Two hundred some skeletons and six hundred orcs? There should definitely be enough for all of it. With some iron left over. Don't know what we might do with that...
