There are few hard facts known about Ravenous and his Seekers. It is believed that he originated in the Negative Zone and was recruited by Annihilus. It is unknown whether Annihilus had a hand in his creation. Those who have entered the Negative Zone have whispered of the Seekers for years. Ravenous has been singled out as their leader. He has been described as an unstoppable force of nature by those who have encountered him and survived.

Seeking to unlock the possibilities of biological application of the Power Cosmic, Annihilus assigned Ravenous and his Seekers the task of finding the famed Heralds of Galactus. He was to capture them alive for experimentation. The Annihilation Wave destroyed the Xandar Cluster, and Ravenous and his Seekers were sent to that region of space to find Air-Walker and Firelord. They were both former Heralds of Galactus, which were native to the planet Xandar.

Ravenous had control of dog like creatures called Currs. The Currs are the Seekers tracking devices. These Currs are attached to the Seekers by glowing umbilical cords. They have no eyes, but they use sensory like tentacles to find their way through the cosmos. Currs appear to come in packs of threes and are conduits of the Opposing Force, allowing them to track the Heralds through hyperspace with no apparent problems. Upon locating Air-Walker, Ravenous became disappointed that Air-Walker was a machine and terminated him in spite of the Silver Surfer interference.

The Seekers tracked the Silver Surfer to the Skrull controlled Tercera Prime Peripheral System of the Andromeda Galaxy; there they were defeated in a futile attempt to apprehend him. After their defeat, the Silver Surfer fled to the Obada’an Rim within the Badoon, Skrull Neutral Zone. He had been summoned there by his former master, Galactus. Sensing the magnitude of the Annihilation Wave, Galactus bestowed a massive gift of the Power Cosmic to his former Herald, thus increasing his power tremendously. The arrogant Ravenous engaged the Herald fiercely, but he was handed a humbling defeat by the newly unleashed power of the Silver Surfer. The Ex-Herald Terrax the Tamer, was not as fortunate as the Silver Surfer. He was tracked and captured by the Seekers on star-sleds.

Ravenous appeared with a group of cosmic warriors on the planet of Daedalus 5 which consisted of: Terrax the Tamer (who was under mind control), Paibok the Power Skrull, a giant Mad Thinker android, and the Infant Terrible. They were ordered to attack the United Front. This group was held to a stale mate by Nova and the others. Ravenous noticed Praxagora, a being from the Negative Zone, standing with the United Front. Not willing to concede the battle, he unleashed the Centurions. They were 100 super powered beings from the planets in the Negative Zone. The United Front fell to the overwhelming might of the new attackers. The Front retreated from the planet.
