Check out my other Respect Thread dealing with Spawn.
Jim Downing was a scientist who was hired by Wynn to create the perfect soldier. He performed many tests on humans to find a way for Wynn to battle the forces of Heaven and Hell. He created beings like Overtkill, Tremor, and many more. Funded by the Mafia that Simmons took down so long ago, this man along with Wynn was close to unlocking the secret. However Hell came to collect on Wynn's promise, Simmons. Simmons was suppose to be the final subject for the experiment, only for Hell to come for Simmons themselves. So Downing instead did the final procedure on himself. In a coma forever, until finally waking up with Simmons death. When he awoke he was given the power of a crazy Angel that attempted to kill God, as well Simmons own K-7 Leetha suit. this combined turned him into the quoted "Ultimate weapon in the Universe".
It takes more than Necro Energy to be a Hell Spawn. You have to have the suit as well of a Spawn. These suits are specially made in the 4th Level of Hell for the Malbolgia's 8th Level Hellspawn. These suit allow Hellspawn to save Necro energy, and perform varying abilities. Simmons suit was specially made from him.
K7-Leetha comes from the 7th House of K. Leetha has a psy link to Spawn himself.
Leetha suits are stated to eat souls for power, and to grow. Something that came to ahead in later Spawn comics with Downing.
