Heralds of Galactus
Elemental converters are a series of devices that Galactus uses to convert a planet into energy for him to feed on.
Galactus has four machines that are built by his four heralds Terrax, Stardust, Air-Walker, and Firelord. The heralds travel to a planet, set up the devices, and activate them for feeding.
However, when they came to Earth, the various heroes of that planet defeated the heralds and destroyed the machines. Galactus reformed the machines but they were all pulled into the Negative Zone.
The machines were not named.
