In Rondo of the Angel and Dragon, that piece of trash trapped in the cracks of time was essentially trapped in the cracks between dimensions. That gave it an extremely special power—both the power of time and the power of dimensions. It could create an infinite number of duplicates at once, making it nearly immortal. One died, and another appeared. Wasn't that somewhat like Zel Duma's ability to regenerate endlessly?
Zel Duma's endless regeneration was probably just a matter of stealing corresponding components from another dimension to replenish itself. Reviving the dead might also mean pulling an identical body over from another world, or perhaps establishing a special connection with other dimensions. As long as the Dimensional Connection System was not destroyed—or every Zel Duma across all dimensions was not destroyed at the same time—Zel Duma could be reborn endlessly.
